.netl发送邮件

.net1.1中，web应该可以使用System.Web.Mail发送邮件。.net2.0后.net framework中添加了一个System.Net.Mail的命名空间，用于发送邮件。
使用System.Web.Mail发送邮件
public class SendMail
{
public static void Send(string mailFrom, string maiFromlAccount,string mailFromPwd, string mailSmtpServer, IList<string> mailTo, IList<string> mailCC, IList<string> mailBCC, string mailTitle, string mailContent, IList<MailAttachment> mailAttachments,System.Text.Encoding encoding,MailFormat format)
{
MailMessage message = new MailMessage();
//定义SMTP邮件服务器需要身份认证
message.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
//认证的用户名
message.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", maiFromlAccount);
//认证密码
message.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", mailFromPwd);
string sMailTo = "";
foreach (string s in mailTo)
{
sMailTo += s + ";";
}
if (sMailTo == "")
{
throw new Exception("接收邮件不可以为空");
}
sMailTo = sMailTo.TrimEnd(';');
if (mailFrom.Trim() == "")
{
throw new Exception("发送邮件不可以为空");
}
message.From = mailFrom;
message.To = sMailTo;
if (mailCC.Count > 0)
{
string sMailCC = "";
foreach (string s in mailCC)
{
sMailCC += s + ";";
}
sMailCC = sMailCC.TrimEnd(';');
message.Cc = sMailCC;
}
if (mailBCC.Count > 0)
{
string sMailBCC = "";
foreach (string s in mailBCC)
{
sMailBCC += s + ";";
}
sMailBCC = sMailBCC.TrimEnd(';');
message.Bcc = sMailBCC;
}
message.Subject = mailTitle;
message.Body = mailContent;
message.BodyEncoding = encoding; //邮件编码
message.BodyFormat = format; //内容格式 html还是text
message.Priority = MailPriority.High; //设置发送的优先集
//附件
foreach (MailAttachment att in mailAttachments)
{
message.Attachments.Add(att);
}
SmtpMail.SmtpServer = mailSmtpServer;
SmtpMail.Send(message);
}

public static void SendText(string mailFrom, string maiFromlAccount, string mailFromPwd, string mailSmtpServer, IList<string> mailTo, IList<string> mailCC, IList<string> mailBCC, string mailTitle, string mailContent)
{
List<MailAttachment> attList = new List<MailAttachment>();
Send(mailFrom, maiFromlAccount, mailFromPwd, mailSmtpServer, mailTo, mailCC, mailBCC, mailTitle, mailContent, attList, Encoding.UTF8, MailFormat.Text);
}

public static void SendHTML(string mailFrom, string maiFromlAccount, string mailFromPwd, string mailSmtpServer, IList<string> mailTo, IList<string> mailCC, IList<string> mailBCC, string mailTitle, string mailContent)
{
List<MailAttachment> attList = new List<MailAttachment>();
Send(mailFrom, maiFromlAccount, mailFromPwd, mailSmtpServer, mailTo, mailCC, mailBCC, mailTitle, mailContent, attList, Encoding.UTF8, MailFormat.Html);
}
}

使用System.Net.Mail发送邮件
public class NetSendMail
{
public static void MailSend(string mailFrom, string maiFromlAccount, string mailFromPwd, string mailSmtpServer, IList<string> mailTo, IList<string> mailCC, IList<string> mailBCC, string mailTitle, string mailContent, IList<string> mailAttachments, System.Text.Encoding encoding, bool isBodyHtml)
{
MailMessage message = new MailMessage();
if (mailFrom.Trim() == "")
{
throw new Exception("发送邮件不可以为空");
}
message.From = new MailAddress(mailFrom);
if (mailTo.Count <= 0)
{
throw new Exception("接收邮件不可以为空");
}
foreach (string s in mailTo)
{
message.To.Add(new MailAddress(s));
}
if (mailCC.Count > 0)
{
foreach (string s in mailCC)
{
message.CC.Add(new MailAddress(s));
}
}
if (mailBCC.Count > 0)
{
foreach (string s in mailBCC)
{
message.Bcc.Add(new MailAddress(s));
}
}
message.Subject = mailTitle;
message.Body = mailContent;
message.BodyEncoding = encoding; //邮件编码
message.IsBodyHtml = isBodyHtml; //内容格式是否是html
message.Priority = MailPriority.High; //设置发送的优先集
//附件
foreach (string att in mailAttachments)
{
message.Attachments.Add(new Attachment(att));
}
SmtpClient smtpClient = new SmtpClient();
smtpClient.Host = mailSmtpServer;
smtpClient.Credentials = new NetworkCredential(maiFromlAccount, mailFromPwd);
smtpClient.Timeout = 1000;
smtpClient.EnableSsl = false; //不使用ssl连接
smtpClient.Send(message);
}

public static void MailSendText(string mailFrom, string maiFromlAccount, string mailFromPwd, string mailSmtpServer, IList<string> mailTo, IList<string> mailCC, IList<string> mailBCC, string mailTitle, string mailContent)
{
List<string> attList = new List<string>();
MailSend(mailFrom, maiFromlAccount, mailFromPwd, mailSmtpServer, mailTo, mailCC, mailBCC, mailTitle, mailContent, attList, Encoding.UTF8, false);
}

public static void MailSendHTML(string mailFrom, string maiFromlAccount, string mailFromPwd, string mailSmtpServer, IList<string> mailTo, IList<string> mailCC, IList<string> mailBCC, string mailTitle, string mailContent)
{
List<string> attList = new List<string>();
MailSend(mailFrom, maiFromlAccount, mailFromPwd, mailSmtpServer, mailTo, mailCC, mailBCC, mailTitle, mailContent, attList, Encoding.UTF8, true);
}
