菜鸟求助:C# TcpClient.Connect (IPAddress, Int32) 大问题

Question

TcpClient.Connect (IPAddress, Int32) 
偶然出现,总是连接成功.... 不管如何改动IPAddress(包括不存在的)
  catch (SocketException e) 捕捉不到.....
为什么如此?

Answer 1

你把整个try都取消在调试一下.或者把整个代码都发出来.这样也才好帮你解决.

Answer 2

代码很简单的,重启了本机还是这个问题....好莫名其妙哦 
public bool Connect()
        {
            try
            {
                if (tcpClient == null)
                {
                    tcpClient = new TcpClient();
                    tcpClient.Connect(IPAddress.Parse(proxyAddress), proxyPort);
                }                if (tcpClient.Connected)
                {
                    return true;
                }
                else
                {
                    Close();
                }
            }
            catch (SocketException e)
            {
                Close();
            }
            catch (Exception e)
            {
                Close();
            }
            return false;
        }

TcpClient tcpClient = new TcpClient();
   Try{
   tcpClient.Connect("www.a.net",4088);
   }
   catch(Exception e){
   MessageBox.Show("连接错误:"+e.Message);
   }
   try{
   NetworkStream stream=tcpClient.GetStream();
   }
   catch(Exception e)
   {
   MessageBox.Show("TcpClient错误："+e.Message);
   }
