這篇文章主要介紹“Lumisoft.NET組件與.NET API實(shí)現(xiàn)郵件發(fā)送功能的對(duì)比分析”，在日常操作中，相信很多人在Lumisoft.NET組件與.NET API實(shí)現(xiàn)郵件發(fā)送功能的對(duì)比分析問(wèn)題上存在疑惑，小編查閱了各式資料，整理出簡(jiǎn)單好用的操作方法，希望對(duì)大家解答”Lumisoft.NET組件與.NET API實(shí)現(xiàn)郵件發(fā)送功能的對(duì)比分析”的疑惑有所幫助！接下來(lái)，請(qǐng)跟著小編一起來(lái)學(xué)習(xí)吧！
1、.NET的郵件發(fā)送功能實(shí)現(xiàn)
.NET本身封裝了一個(gè)SmtpClient類以及相關(guān)的郵件對(duì)象類，這樣利用這些類庫(kù)，也可以方便實(shí)現(xiàn)郵件的發(fā)送功能的了。
如添加發(fā)送人地址，抄送地址，以及暗送地址（多個(gè)地址用逗號(hào)分開(kāi)）代碼如下。
復(fù)制代碼 代碼如下:
string toEmails = mailInfo.ToEmail;
string bcc = "";
mailInfo.RecipientBCC.ForEach(obj => bcc += string.Format("{0},", obj));
bcc = bcc.Trim(',');
string cc = "";
mailInfo.RecipientCC.ForEach(obj => cc += string.Format("{0},", obj));
cc = cc.Trim(',');
MailMessage mail = new MailMessage(settingInfo.MailFrom, toEmails);
if (!string.IsNullOrEmpty(bcc))
{
mail.Bcc.Add(bcc);
}
if (!string.IsNullOrEmpty(cc))
{
mail.CC.Add(cc);
}
.NET的附件和嵌入式資源由對(duì)象Attachment和LinkedResource進(jìn)行管理，他們的利用代碼如下所示：
復(fù)制代碼 代碼如下:
//附件
foreach (string fileName in mailInfo.Attachments)
{
mail.Attachments.Add(new Attachment(fileName));
}
//嵌入資源
AlternateView view = AlternateView.CreateAlternateViewFromString(mailInfo.Body, Encoding.UTF8, MediaTypeNames.Text.Html);
foreach (LinkedAttachementInfo link in mailInfo.EmbedObjects)
{
LinkedResource resource = new LinkedResource(link.Stream, link.MimeType);
resource.ContentId = link.ContentId;
view.LinkedResources.Add(resource);
}
mail.AlternateViews.Add(view);
發(fā)送郵件的其他部分代碼如下所示
復(fù)制代碼 代碼如下:
mail.IsBodyHtml = mailInfo.IsBodyHtml;
mail.BodyEncoding = Encoding.UTF8;
mail.Subject = mailInfo.Subject;
mail.SubjectEncoding = Encoding.UTF8;
//發(fā)送賬戶設(shè)置信息
SmtpClient client = new SmtpClient();
client.Host = settingInfo.SmtpServer;
client.Port = settingInfo.SmptPort;
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Credentials = new NetworkCredential(settingInfo.SmtpUser, settingInfo.SmtpPass);
bool success = false;
try
{
client.Send(mail);
success = true;
}
catch (Exception ex)
{
LogTextHelper.Error(ex);
//throw;
}
上面利用.net的SmtpClient發(fā)送郵件操作的完整代碼如下:
復(fù)制代碼 代碼如下:
///
/// 發(fā)送外部郵件（系統(tǒng)配置，系統(tǒng)郵件）
///
/// 發(fā)送郵件信息
///
public CommonResult Send(MailInfo mailInfo)
{
CommonResult result = new CommonResult();
try
{
AppConfig config = new AppConfig();
string MailDomain = config.AppConfigGet("MailDomain");
string MailUsername = config.AppConfigGet("MailUsername");
string MailPassword = config.AppConfigGet("MailPassword");
string MailPort = config.AppConfigGet("MailPort");
string MailFrom = config.AppConfigGet("MailFrom");
int port = 25;
int.TryParse(MailPort, out port);
SmtpSettingInfo settingInfo = new SmtpSettingInfo(MailDomain, port,
MailUsername, MailPassword, MailFrom);
result.Success = PrivateSendEmail(mailInfo, settingInfo);
}
catch (Exception ex)
{
result.ErrorMessage = ex.Message;
throw;
}
return result;
}
///
/// 通用發(fā)送郵件操作
///
private static bool PrivateSendEmail(MailInfo mailInfo, SmtpSettingInfo settingInfo)
{
string toEmails = mailInfo.ToEmail;
string bcc = "";
mailInfo.RecipientBCC.ForEach(obj => bcc += string.Format("{0},", obj));
bcc = bcc.Trim(',');
string cc = "";
mailInfo.RecipientCC.ForEach(obj => cc += string.Format("{0},", obj));
cc = cc.Trim(',');
MailMessage mail = new MailMessage(settingInfo.MailFrom, toEmails);
if (!string.IsNullOrEmpty(bcc))
{
mail.Bcc.Add(bcc);
}
if (!string.IsNullOrEmpty(cc))
{
mail.CC.Add(cc);
}
//附件
foreach (string fileName in mailInfo.Attachments)
{
mail.Attachments.Add(new Attachment(fileName));
}
//嵌入資源
AlternateView view = AlternateView.CreateAlternateViewFromString(mailInfo.Body, Encoding.UTF8, MediaTypeNames.Text.Html);
foreach (LinkedAttachementInfo link in mailInfo.EmbedObjects)
{
LinkedResource resource = new LinkedResource(link.Stream, link.MimeType);
resource.ContentId = link.ContentId;
view.LinkedResources.Add(resource);
}
mail.AlternateViews.Add(view);
mail.IsBodyHtml = mailInfo.IsBodyHtml;
mail.BodyEncoding = Encoding.UTF8;
mail.Subject = mailInfo.Subject;
mail.SubjectEncoding = Encoding.UTF8;
//發(fā)送賬戶設(shè)置信息
SmtpClient client = new SmtpClient();
client.Host = settingInfo.SmtpServer;
client.Port = settingInfo.SmptPort;
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Credentials = new NetworkCredential(settingInfo.SmtpUser, settingInfo.SmtpPass);
bool success = false;
try
{
client.Send(mail);
success = true;
}
catch (Exception ex)
{
LogTextHelper.Error(ex);
//throw;
}
string message = string.Format("發(fā)送給【{0}】的郵件“{1}”，{2}，時(shí)間：{3}",
mailInfo.ToEmail[0], mailInfo.Subject, success ? "發(fā)送成功" : "發(fā)送失敗", DateTime.Now);
LogTextHelper.Info(message);
return success;
}
2、基于Lumisoft.NET組件的郵件發(fā)送功能實(shí)現(xiàn)
基于Lumisoft.NET組件的郵件發(fā)送，也是一種很常用的，因?yàn)檫@個(gè)開(kāi)源組件非常強(qiáng)大，經(jīng)常可以在一些程序中被使用。
這個(gè)發(fā)送郵件的功能主要是利用SMTP_Client類來(lái)實(shí)現(xiàn)的，如下代碼所示。注意其中的Authenticate函數(shù)已經(jīng)被舍棄，可以使用Auth方法進(jìn)行驗(yàn)證。但是函數(shù)參數(shù)有所不同，根據(jù)驗(yàn)證對(duì)象，使用不同的驗(yàn)證方式，一般選擇AUTH_SASL_Client_Plain對(duì)象即可。
復(fù)制代碼 代碼如下:
public bool Send()
{
bool sended = false;
using (SMTP_Client client = new SMTP_Client())
{
client.Connect(smtpServer, smtpPort, smtpUseSsl);
client.EhloHelo(smtpServer);
var authhh = new AUTH_SASL_Client_Plain(username, password);
client.Auth(authhh);
//client.Authenticate(username, password);
//string text = client.GreetingText;
client.MailFrom(from, -1);
foreach (string address in toList.Keys)
{
client.RcptTo(address);
}
//采用Mail_Message類型的Stream
Mail_Message m = Create_PlainText_Html_Attachment_Image(toList, ccList, from, fromDisplay, subject, body, attachments);
using (MemoryStream stream = new MemoryStream())
{
m.ToStream(stream, new MIME_Encoding_EncodedWord(MIME_EncodedWordEncoding.Q, Encoding.UTF8), Encoding.UTF8);
stream.Position = 0;
client.SendMessage(stream);
sended = true;
}
if (m != null)
{
m.Dispose();
}
client.Disconnect();
}
return sended;
}
構(gòu)造用于SMTP發(fā)送的數(shù)據(jù)，可以使用Mail_Message 對(duì)象，也可以使用Mime對(duì)象，雖然讀都可以實(shí)現(xiàn)發(fā)送功能，不過(guò)Mime對(duì)象是舍棄的對(duì)象了。
構(gòu)造Mail_Message對(duì)象后，創(chuàng)建用于發(fā)送的格式要轉(zhuǎn)換為Stream對(duì)象。轉(zhuǎn)換為發(fā)送的Stream操作如下所示。
復(fù)制代碼 代碼如下:
using (MemoryStream stream = new MemoryStream())
{
m.ToStream(stream, new MIME_Encoding_EncodedWord(MIME_EncodedWordEncoding.Q, Encoding.UTF8), Encoding.UTF8);
stream.Position = 0;
client.SendMessage(stream);
sended = true;
}
構(gòu)造Mail_Message格式的郵件操作如下所示。
復(fù)制代碼 代碼如下:
private Mail_Message Create_PlainText_Html_Attachment_Image(Dictionary
string subject, string body, Dictionary
{
Mail_Message msg = new Mail_Message();
msg.MimeVersion = "1.0";
msg.MessageID = MIME_Utils.CreateMessageID();
msg.Date = DateTime.Now;
msg.Subject = subject;
msg.From = new Mail_t_MailboxList();
msg.From.Add(new Mail_t_Mailbox(mailFromDisplay, mailFrom));
msg.To = new Mail_t_AddressList();
foreach (string address in tomails.Keys)
{
string displayName = tomails[address];
msg.To.Add(new Mail_t_Mailbox(displayName, address));
}
msg.Cc = new Mail_t_AddressList();
foreach (string address in ccmails.Keys)
{
string displayName = ccmails[address];
msg.Cc.Add(new Mail_t_Mailbox(displayName, address));
}
//設(shè)置回執(zhí)通知
if (!string.IsNullOrEmpty(notifyEmail) && ValidateUtil.IsEmail(notifyEmail))
{
msg.DispositionNotificationTo.Add(new Mail_t_Mailbox(notifyEmail, notifyEmail));
}

MIME_h_ContentType contentType_multipartMixed = new MIME_h_ContentType(MIME_MediaTypes.Multipart.mixed);
contentType_multipartMixed.Param_Boundary = Guid.NewGuid().ToString().Replace('-', '.');
MIME_b_MultipartMixed multipartMixed = new MIME_b_MultipartMixed(contentType_multipartMixed);
msg.Body = multipartMixed;
//--- multipart/alternative -----------------------------
MIME_Entity entity_multipartAlternative = new MIME_Entity();
MIME_h_ContentType contentType_multipartAlternative = new MIME_h_ContentType(MIME_MediaTypes.Multipart.alternative);

MIME_b_MultipartAlternative multipartAlternative = new MIME_b_MultipartAlternative(contentType_multipartAlternative);
entity_multipartAlternative.Body = multipartAlternative;
multipartMixed.BodyParts.Add(entity_multipartAlternative);
//--- text/plain ----------------------------------------
MIME_Entity entity_text_plain = new MIME_Entity();
MIME_b_Text text_plain = new MIME_b_Text(MIME_MediaTypes.Text.plain);
entity_text_plain.Body = text_plain;
//普通文本郵件內(nèi)容，如果對(duì)方的收件客戶端不支持HTML，這是必需的
string plainTextBody = "如果你郵件客戶端不支持HTML格式，或者你切換到“普通文本”視圖，將看到此內(nèi)容";
if (!string.IsNullOrEmpty(plaintTextTips))
{
plainTextBody = plaintTextTips;
}
text_plain.SetText(MIME_TransferEncodings.QuotedPrintable, Encoding.UTF8, plainTextBody);
multipartAlternative.BodyParts.Add(entity_text_plain);
//--- text/html -----------------------------------------
string htmlText = body;//"這是一份測(cè)試郵件，![](\"cid:test.jpg\")

MIME_Entity entity_text_html = new MIME_Entity();
MIME_b_Text text_html = new MIME_b_Text(MIME_MediaTypes.Text.html);
entity_text_html.Body = text_html;
text_html.SetText(MIME_TransferEncodings.QuotedPrintable, Encoding.UTF8, htmlText);
multipartAlternative.BodyParts.Add(entity_text_html);

WebClient client = new WebClient();
foreach (string attach in attachments.Keys)

}
}
catch (Exception ex)
{
LogTextHelper.Error(ex);
}
}
#endregion
return msg;
}
而構(gòu)造Mime格式的操作如下所示。
復(fù)制代碼 代碼如下:
private Mime Create_Html_Attachment_Image(string mailTo, string mailFrom, string mailFromDisplay,
string subject, string body, List
string replyEmail = "")
{
Mime m = new Mime();
MimeEntity mainEntity = m.MainEntity;
mainEntity.From = new AddressList();
mainEntity.From.Add(new MailboxAddress(mailFromDisplay, mailFrom));
mainEntity.To = new AddressList();
mainEntity.To.Add(new MailboxAddress(mailTo, mailTo));
mainEntity.Subject = subject;
mainEntity.ContentType = MediaType_enum.Multipart_mixed;
//設(shè)置回執(zhí)通知
if (!string.IsNullOrEmpty(notifyEmail) && ValidateUtil.IsEmail(notifyEmail))
{
mainEntity.DSN = notifyEmail;
}
//設(shè)置統(tǒng)一回復(fù)地址
if (!string.IsNullOrEmpty(replyEmail) && ValidateUtil.IsEmail(replyEmail))
{
mainEntity.ReplyTo = new AddressList();
mainEntity.ReplyTo.Add(new MailboxAddress(replyEmail, replyEmail));
}
MimeEntity textEntity = mainEntity.ChildEntities.Add();
textEntity.ContentType = MediaType_enum.Text_html;
textEntity.ContentTransferEncoding = ContentTransferEncoding_enum.QuotedPrintable;
textEntity.DataText = body;
//附件
foreach (string attach in attachments)
{
MimeEntity attachmentEntity = mainEntity.ChildEntities.Add();
attachmentEntity.ContentType = MediaType_enum.Application_octet_stream;
attachmentEntity.ContentDisposition = ContentDisposition_enum.Attachment;
attachmentEntity.ContentTransferEncoding = ContentTransferEncoding_enum.Base64;
FileInfo file = new FileInfo(attach);
attachmentEntity.ContentDisposition_FileName = file.Name;
attachmentEntity.DataFromFile(attach);
}
//嵌入圖片
foreach (string key in embedImages.Keys)
{
MimeEntity attachmentEntity = mainEntity.ChildEntities.Add();
attachmentEntity.ContentType = MediaType_enum.Application_octet_stream;
attachmentEntity.ContentDisposition = ContentDisposition_enum.Inline;
attachmentEntity.ContentTransferEncoding = ContentTransferEncoding_enum.Base64;
string imageFile = embedImages[key];
FileInfo file = new FileInfo(imageFile);
attachmentEntity.ContentDisposition_FileName = file.Name;
//string displayName = Path.GetFileNameWithoutExtension(fileName);
attachmentEntity.ContentID = key;//BytesTools.BytesToHex(Encoding.Default.GetBytes(fileName));
attachmentEntity.DataFromFile(imageFile);
}
return m;
}
綜合以上兩者的發(fā)送功能，都可以實(shí)現(xiàn)郵件的發(fā)送操作，如下界面是發(fā)送郵件界面。
3、LumiSoft.NET存儲(chǔ)eml郵件文件以及發(fā)送eml文件操作
除了上面的發(fā)送普通郵件，Lumisoft還支持吧郵件序列號(hào)存儲(chǔ)到文件(.eml郵件文件)里面，然后也可以通過(guò)把文件讀取到流里面，進(jìn)行發(fā)送，對(duì)于某種場(chǎng)合，可以把郵件存儲(chǔ)到eml文件是一個(gè)很好的操作。
存儲(chǔ)EML文件的相關(guān)操作如下所示。
復(fù)制代碼 代碼如下:
private void btnCreateFile_Click(object sender, EventArgs e)
{
string attachFile = Path.Combine(Application.StartupPath, "Attachment/Hotel2.png");
List
attachments.Add(attachFile);
string subject = "測(cè)試郵件";
string body = "這是一份測(cè)試郵件，來(lái)自LumiSoft.Net";
string bodyEmbedy = "這是一份測(cè)試郵件，來(lái)自LumiSoft.Net";
Dictionary
embedList.Add("test.jpg", "C:\\test.jpg");
//存儲(chǔ)為Eml文件
string path = Path.Combine(Application.StartupPath, "Eml");
DirectoryUtil.AssertDirExist(path);
string emlFile = string.Format("{0}/{1}.eml", path, DateTime.Now.ToFileTime());
Mime m = Create_Html_Attachment_Image(to, from, from, subject, bodyEmbedy, attachments, embedList);
m.ToFile(emlFile);
MessageUtil.ShowTips("OK");
}
發(fā)送EML文件操作如下所示。
復(fù)制代碼 代碼如下:
private void btnSendFile_Click(object sender, EventArgs e)
{
using (SMTP_Client client = new SMTP_Client())
{
int smtpPort = smtpUseSsl ? WellKnownPorts.SMTP_SSL : WellKnownPorts.SMTP;
client.Connect(smtpServer, smtpPort, smtpUseSsl);
client.EhloHelo(smtpServer);
//var authhh = new AUTH_SASL_Client_Plain(username, password);
//client.Auth(authhh);
client.Authenticate(username, password);
//string text = client.GreetingText;
client.MailFrom(from, -1);
client.RcptTo(to);
string path = Path.Combine(Application.StartupPath, "Eml");
string emlFile = Directory.GetFiles(path)[0];
var msg = Mail_Message.ParseFromFile(emlFile);
MemoryStream stream = new MemoryStream();
msg.ToStream(stream, new MIME_Encoding_EncodedWord(MIME_EncodedWordEncoding.Q, Encoding.UTF8), Encoding.UTF8);
stream.Position = 0;
client.SendMessage(stream);
client.Disconnect();
}
MessageUtil.ShowTips("OK");
}
