的TcpListener（端口）遇到错误C＃FILESHARING

Question

我尽量让在TCP/IP文件共享的客户端可以发送或上传文件到服务器

但是当文件发送到服务器，服务器不接收任何文件

这是我的代码

FileSharingClient.cs

    { 
     private static string shortFileName = ""; 
     private static string fileName = ""; 
     public Form1() 
     { 
      InitializeComponent(); 
     } 

     private void btnBrowse_Click(object sender, EventArgs e) 
     { 
      OpenFileDialog dlg = new OpenFileDialog(); 
      dlg.Title = "File Sharing Client"; 
      dlg.ShowDialog(); 
      txtFile.Text = dlg.FileName; 
      fileName = dlg.FileName; 
      shortFileName = dlg.SafeFileName; 
     }

      string fileName = txtFile.Text; 
      Task.Factory.StartNew(() => SendFile(ipAddress,port,fileName,shortFileName));

     }

        TcpClient clientSocket = new TcpClient(remoteHostIP, remoteHostPort); 
        NetworkStream networkStream = clientSocket.GetStream(); 
        networkStream.Write(clientData, 0, clientData.GetLength(0)); 
        networkStream.Close(); 
       } 
      } 
      catch 
      { 

      } 
     }

     } 
    }

          int fileNameLen = BitConverter.ToInt32(dataByte, 0); 
          fileName = Encoding.ASCII.GetString(dataByte, 4, fileNameLen); 
          Stream fileStream = File.OpenWrite(folderPath + fileName); 
          fileStream.Write(dataByte, 4+fileNameLen,(1024-(4+fileNameLen)));

       } 

      } 
      catch 
      { 

      } 
     } 
    } 
} 

在这条线（FileSharingServer）

TcpListener tcpListener = new TcpListener(port); 

和我在我的FileSharingServer一个错误消息，这是

Warning 1 'System.Net.Sockets.TcpListener.TcpListener(int)' is obsolete: '"This method has been deprecated. Please use TcpListener(IPAddress localaddr, int port) instead. http://go.microsoft.com/fwlink/?linkid=14202"' 

任何人都可以修复它？ 感谢

你需要指定IP地址和端口上侦听：

TcpListener tcpListener = new TcpListener(System.Net.IPAddress.Any, port);
