关于.net发送EMAIL的总结

①导入相应的包：

   using System.Web.Mail;  
   using System.Net.Mail;  
   using System.Net;  

 ②建立发送Email的方法：

    /// <summary>  
    ///  发送EMail  
    /// </summary>  
    /// <param name="title">标题</param>  
    /// <param name="body">内容</param>  
    /// <param name="toAdress">发送到哪</param>  
    /// <param name="fromAdress">从哪发送</param>  
    /// <param name="userName">用户名</param>  
    /// <param name="userPwd">密码</param>  
   /// <param name="smtpHost">smtp服务器</param>  
   private void sendMail(string title, string body, string toAdress, string fromAdress,   
                                                  string userName, string userPwd, string smtpHost)  
   {  
       try  
       {  
           MailAddress to = new MailAddress(toAdress);  
           MailAddress from = new MailAddress(fromAdress);  
           System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(from, to);  
           message.Subject = title; message.Body = body;  
           SmtpClient smtp = new SmtpClient();  
           smtp.UseDefaultCredentials = true;  
           smtp.Port = 25;  
           smtp.Credentials = new NetworkCredential(userName, userPwd);  
           smtp.DeliveryMethod = SmtpDeliveryMethod.Network;  
           smtp.Host = smtpHost;   
           message.To.Add(toAdress);  
           smtp.Send(message);  
       }  
       catch (Exception ex) {  
          Response.Write(ex.Message);  
      }  
   }  

 ③测试发送Email：

    sendMail("標題", "內容", "[e-mail]", "[e-mail]", "test", "123456", "smtp.126.com");
