Question

我有一个简单的多线程C＃服务器和客户端。当只连接一个客户端时，我可以很好地与它进行交互，但是当连接两个或更多客户端时，我似乎正在使用最后一个NetworkStream。我希望能够做的是提供一个输入命令，指定要读取和写入的流。因此，例如，第一个客户端是“客户端1”，第二个客户端是“客户端2”。我只需在命令文本框中键入“Client 2”，它就会获得第二个客户端的流。

问题是，我不知道如何将文本分配给客户端。以下是服务器的相关代码：

    private void ClientThread(Object client)
    {
        NetworkStream networkStream = ((TcpClient)client).GetStream();
        Dictionary<int, NetworkStream> myClients = new Dictionary<int, NetworkStream>(); // This didn't work.
        myClients.Add(counter, ((TcpClient)client).GetStream()); // Wouldn't write.
counter = counter + 1;
        streamReader = new StreamReader(networkStream);
        streamWriter = new StreamWriter(networkStream);
        strInput = new StringBuilder();          
        while (true)
        {
            try
            {
                strInput.Append(streamReader.ReadLine());
                strInput.Append("\r\n");
            }
            catch (Exception error)
            {
                break;
            }
            Application.DoEvents();
            DisplayMessage(strInput.ToString());
            strInput.Remove(0, strInput.Length);
        }
    }

    private void textBox2_KeyDown(object sender, KeyEventArgs e)
    {
        try
        {
            if (e.KeyCode == Keys.Enter)
            {                 
                //ListView.SelectedListViewItemCollection stuff = listView1.SelectedItems;
                //ip is displayed in listView1, if I could also bind the stream for the ip 
                //to it and select it, that would be cool.
                {
                    strInput.Append(textBox2.Text.ToString());
                    streamWriter.WriteLine(strInput);
                    streamWriter.Flush();
                    strInput.Remove(0, strInput.Length);
                    if (textBox2.Text == "cls") textBox1.Text = "";
                    textBox2.Text = "";
                }
            }
        }
        catch (Exception error) { }
    }

那么，我该怎么做呢？

Answer 1

NetworkStream networkStream = myClients[2];
using(streamWriter = new StreamWriter(networkStream))
{
    streamWriter.WriteLine("hello client 2"); // send something to Client 2
}

networkStream = myClients[4];
using(streamWriter = new StreamWriter(networkStream))
{
    streamWriter.WriteLine("hello client 4"); // send something to Client 4
}

您显然将所有客户端流存储到字典中。只需将该流加载到StreamWriter并发送您的数据即可。制作字典myClients类字段，然后像上面一样获取当前活动的流。

多个客户端的问题并获取特定的流
