求救!关于StreamReader

private void thStart(object obj)
        {
            Console.WriteLine("建立分支点对点连接...");
            NetworkStream NS = (NetworkStream)obj;
            SR = new StreamReader(NS);
            SW = new StreamWriter(NS);
            while (true)
            {
                if (NS.DataAvailable)
                {
                    Console.WriteLine("开始接受客户端命令...");
                    byte[] stream = new byte[256];
                    NS.Read(stream, 0, stream.Length);
                    Console.WriteLine(System.Text.Encoding.UTF8.GetString(stream));
                    SW.WriteLine("登陆成功拉");
                    SW.Flush();
                    string order = SR.ReadLine();
                    Console.WriteLine("命令：{0}", order);
                    string[] spliter = order.Split(',');
                    switch (spliter[0])
                    {
                        //用户登录
                        case "Login":
                            Console.WriteLine("用户试图登陆");
                            SW.Write("Login,1");
                            break;
                        //读取用户列表
                        case "ReadUserList":
                            string tempStr = "ReadUserList,";
                            for (int i = 0; i < UserListTable.Count; i++)
                            {
                                tempStr += UserListTable[i];
                            }
                            SW.Write(tempStr);
                            break;
                    }
                }
            }
        }

为什么我的string order = SR.ReadLine();
读取不到数据？而且程序卡到这不能继续执行~~ --------------------编程问答-------------------- 怎么没人回答呢?555555555555555 --------------------编程问答-------------------- 没有人知道吗?? --------------------编程问答-------------------- 真的没人知道吗?

void StreamFile(Socket clientSocket)
{
  NetworkStream networkStream =
    new NetworkStream(clientSocket);
  System.IO.StreamWriter streamWriter =
    new System.IO.StreamWriter(networkStream);
  System.IO.StreamReader streamReader =
    new System.IO.StreamReader(@"C:\a.txt");

  do {
   strStream = streamReader.ReadLine();
   if(strStream != null )
   {
    streamWriter.WriteLine(strStream);
    streamWriter.Flush();
   }
  } while (strStream != null);
  streamReader.Close();
  networkStream.Close();
  streamWriter.Close();
}

//Client1 Code
using System.Net.Sockets;

    }
   }
  } while (strOut != null );
} catch() {}

纯属顶贴 --------------------编程问答-------------------- 汗，刚才回复了，怎么就不见了，谁给俺删了！
NS.Read(stream, 0, stream.Length);
改为BeginRead 和 EndRead试试
------------
纯属试试
--------------------编程问答-------------------- 有可能是你的socket收发数据没成功 --------------------编程问答-------------------- SR.ReadLine();
是要读入一行才能返回，也就是发来的数据中要有换行标记，就是说发送的数据结尾要有'\n' 要是不行试一下 '\r\n'.

补充：.NET技术 ,  C#
