C# 实现拨号重连

先断开网络连接

 /// <summary>
 /// 断开网络连接
 /// </summary>
 public static void Logout()
         {
             ReadOnlyCollection<RasConnection> conList = RasConnection.GetActiveConnections();
             foreach (RasConnection con in conList)
             {
                 con.HangUp();
             }
         }

重新拨号

 /// <summary>
 /// 开始拨号
 /// </summary>
 /// <returns>返回拨号进程的返回值</returns>
         public static int Connect()
         {
             //联网参数
             string intername = Common.DESEncrypt.DesDecrypt(Common.MethodClass.GetConfigValue("intername").ToString());
             string interpwd = Common.DESEncrypt.DesDecrypt(Common.MethodClass.GetConfigValue("interpwd").ToString());

             ProcessWindowStyle _windowstyle = ProcessWindowStyle.Hidden;
             Process pro = new Process();
             pro.StartInfo.FileName = "rasdial.exe";

 //intername宽带用户名，interpwd宽度密码
             pro.StartInfo.Arguments = "宽带连接" + " " + intername + " " + interpwd;
             pro.StartInfo.WindowStyle = _windowstyle;
             pro.Start();
             pro.WaitForExit();
             return pro.ExitCode;
         }

调用

  public void buttonItem2_Click(object sender, EventArgs e)
         {
             Logout();
             if (Connect() == )
             {
                 //拨号成功
             }
             else
             {
                 //拨号失败
             }
         }
