下面用到的邮件账号和密码都不是真实的，需要测试就换成自己的邮件账号。
需要引用：
1 using System.Net.M
2 using System.T
3 using System.N
程序代码：
MailMessage myMail = new MailMessage(); //创建邮件实例对象
myMail.From = new MailAddress(""); //发送者，要和邮件服务器的验证信息对应，不能随便更改
myMail.To.Add(new MailAddress("")); //接收者
myMail.Subject = "C#发送Email"; //邮件标题
myMail.SubjectEncoding = Encoding.UTF8; //标题编码
myMail.Body = "this is a test email!"; //邮件内容
myMail.BodyEncoding = Encoding.UTF8; //邮件内容编码
myMail.IsBodyHtml = true;
//邮件内容是否支持html
SmtpClient smtp = new SmtpClient(); //创建smtp实例对象
smtp.Host = ""; //邮件服务器SMTP
smtp.Port = 25;
//邮件服务器端口
smtp.Credentials = new NetworkCredential("", "123456"); //邮件服务器验证信息
smtp.Send(myMail); //发送邮件
使用Gmail邮箱发送邮件示例
MailMessage myMail = new MailMessage();
myMail.From = new MailAddress("");
myMail.To.Add(new MailAddress(""));
myMail.Subject = "C#发送Email";
myMail.SubjectEncoding = Encoding.UTF8;
myMail.Body = "this is a test email from gmail!&a href='.cn'&sina&/a&";
myMail.BodyEncoding = Encoding.UTF8;
myMail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "";
smtp.Port = 587; //Gmail的smtp端口
smtp.Credentials = new NetworkCredential("", "123456");
smtp.EnableSsl = true; //Gmail要求SSL连接
smtp.DeliveryMethod = SmtpDeliveryMethod.N //Gmail的发送方式是通过网络的方式，需要指定
smtp.Send(myMail);
使用QQ邮箱发送邮件示例
MailMessage myMail = new MailMessage();
myMail.From = new MailAddress("");
myMail.To.Add(new MailAddress(""));
myMail.Subject = "C#发送Email";
myMail.SubjectEncoding = Encoding.UTF8;
myMail.Body = "this is a test email from QQ!";
myMail.BodyEncoding = Encoding.UTF8;
myMail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "";
smtp.Credentials = new NetworkCredential("", "123456");
smtp.Send(myMail);
