使用System.Net.Mail通过gmail发送电子邮件

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

                Program prg 
= new Program();
                prg.Host 
= "smtp.gmail.com";
                prg.SmtpUsername 
= "[email protected]";
                prg.SmtpPassword 
= "xxxxxxxx";
                prg.Port 
= 587;
                prg.Send(
"[email protected]","[email protected]",  "test""test"nullnull);
            }

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

            }

            Console.Read();
        }


        
private string _host;

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

public int Port

set { _port = value; }
        }

        }

public string 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

            client.Send(message);
            
        }


    }

}
