<div>
添加引用
using System.Net;
using System.Net.Mail;
public bool SendEmail(string s_body, out string msg)
{
msg = string.Empty;
System.Web.HttpContext context = System.Web.HttpContext.Current;
bool _ret = false;
string s_from = "";//邮件发送人
string pwd = "";//邮件发送人密码
string s_to = "<a>cdcsystem@126.com";//</a>邮件接收人
//s_body = context.Server.HtmlEncode(s_body);
int i = s_from.IndexOf("@");
string username = s_from.Substring(0, i);
//构建MailMessage对象
MailAddress from = new MailAddress(s_from);
MailAddress to = new MailAddress(s_to);
MailMessage mailobj = new MailMessage(from, to);
//完善MailMessage对象
mailobj.Subject = "CDC使用情况";
mailobj.Body = s_body;
mailobj.IsBodyHtml = true;
mailobj.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312");
mailobj.Priority = MailPriority.High;
//构建SmtpClient对象
SmtpClient smtp = new SmtpClient("smtp.126.com");
// smtp.Host = "smtp.163.com";
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential(username, pwd);
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
try
{
smtp.Send(mailobj);
_ret = true;
}
catch(Exception ex)
{
_ret = false;
msg = ex.Message;
}
return _ret;
}

使用方法
string msg = string.Empty;
if (SendEmail("测试",out msg))
{
MessageBox.Show("发送成功");
}
else
{
MessageBox.Show(msg,"发送失败");
}
</div>
