C# 从TCP客户端获取响应

我创建了这个TCP客户端，但在获取响应时遇到问题。它停在第47行

var line = sr.ReadLine();

但有时它会将响应放在日志框中，并再次停留在第24行

 void log(string x)
        {
            richTextBox1.Text += x + Environment.NewLine;
        }

以下是代码：

如何修复它？

您必须首先从TcpClient获取网络流。然后开始读它

使用以下代码

TcpClient tcpClient = new TcpClient ();

// Uses the GetStream public method to return the NetworkStream.
NetworkStream netStream = tcpClient.GetStream ();

if (netStream.CanRead)
    {
        // Reads NetworkStream into a byte buffer. 
        byte[] bytes = new byte[tcpClient.ReceiveBufferSize];

        // Read can return anything from 0 to numBytesToRead.  
        // This method blocks until at least one byte is read.
        netStream.Read (bytes, 0, (int)tcpClient.ReceiveBufferSize);

        // Returns the data received from the host to the console. 
        string returndata = Encoding.UTF8.GetString (bytes);

        Console.WriteLine ("This is what the host returned to you: " + returndata);

    }

您想确切地修复什么？它“粘住”在

ReadLine（）

，因为该操作会阻塞，直到遇到新行，而新行可能尚未发送或接收。
