gmail的smtp采用了ssl连接:
     Outgoing Mail (SMTP) Server - requires TLS: smtp.gmail.com (use authentication)
     Use Authentication: Yes
     Use STARTTLS: Yes (some clients call this SSL)
     Port: 465 or 587

知道了gmail的发信细节,用System.Net.Mail,就是下面这段代码就可以了
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Mail;

namespace GMailSend
{
    
class Program
    
{
        
static void Main(string[] args)
        
{
            
try
            
{
                Program prg 
= new Program();
                prg.Host 
= "smtp.gmail.com";
                prg.SmtpUsername 
= "zhangshanyou@gmail.com";
                prg.SmtpPassword 
= "xxxxxxxx";
                prg.Port 
= 587;
                prg.Send(
"zhangshanyou@gmail.com","33235911@qq.com",  "test""test"nullnull);
            }

            
catch (Exception ex)
            
{
                Console.WriteLine(ex.Message);

            }

            Console.Read();
        }


        
private string _host;

        
public string Host
        
{
            
get return _host; }
            
set { _host = value; }
        }

        
private int _port;

        
public int Port
        
{
            
get return _port; }
            
set { _port = value; }
        }

        
private string _smtpUsername;

        
public string SmtpUsername
        
{
            
get return _smtpUsername; }
            
set { _smtpUsername = value; }
        }

        
private string _smtpPassword;

        
public string SmtpPassword
        
{
            
get return _smtpPassword; }
            
set { _smtpPassword = value; }
        }


        
public void Send(string from, string to, string subject, string body, string[] cc, string[] bcc)
        
{
            
// Create mail message
            MailMessage message = new MailMessage(from, to, subject, body);
            message.BodyEncoding 
= Encoding.GetEncoding(936);

            
if (cc != null && cc.Length > 0)
            
{
                
foreach (string ccAddress in cc)
                
{
                    message.CC.Add(
new MailAddress(ccAddress));
                }

            }

            
if (bcc != null && bcc.Length > 0)
            
{
                
foreach (string bccAddress in bcc)
                
{
                    message.Bcc.Add(
new MailAddress(bccAddress));
                }

            }


            
// Send email
            SmtpClient client = new SmtpClient(this._host, this._port);
            
if (!String.IsNullOrEmpty(this._smtpUsername) && !String.IsNullOrEmpty(this._smtpPassword))
            
{
                client.Credentials 
= new NetworkCredential(this._smtpUsername, this._smtpPassword);
            }

            client.EnableSsl 
= true;

            client.Send(message);
            
        }


    }

}

public void Send(string from, string to, string subject, string body, string[] cc, string[] bcc)
{
// Create mail message
MailMessage message = new MailMessage(from, to, subject, body);
message.BodyEncoding = Encoding.GetEncoding(936);

if (cc != null && cc.Length > 0)

foreach (string ccAddress in cc)

message.CC.Add(new MailAddress(ccAddress));
}
}
if (bcc != null && bcc.Length > 0)
{
foreach (string bccAddress in bcc)
{
message.Bcc.Add(new MailAddress(bccAddress));
}
}

//能解释一下这段代码吗?
谢谢
