【问题描述】:
为了习惯使用客户端服务器通信的套接字,这里是我的代码。
//server partl
try
{
IPAddress ipAd = IPAddress.Parse("127.0.0.1"); //use local m/c IP address, and use the same in the client
/* Initializes the Listener */
TcpListener myList = new TcpListener(ipAd, 8020);
/* Start Listeneting at the specified port */
myList.Start();
Socket s = myList.AcceptSocket();
Console.WriteLine("Connection accepted from " + s.RemoteEndPoint);
byte[] b = new byte[100];
int k = s.Receive(b);
//Console.WriteLine("Recieved...");
//Writes to label1
for (int i = 0; i < k; i++)
label1.Text = b[i].ToString();
//ASCII endoing to use ACK.
ASCIIEncoding asen = new ASCIIEncoding();
s.Send(asen.GetBytes("The string was recieved by the server."));
Console.WriteLine("\nSent Acknowledgement");
/* clean up */
s.Close();
myList.Stop();
}
catch (Exception ex)
{
Console.WriteLine("Error..... " + ex.StackTrace);
}
//Client part
try
{
TcpClient tcpclnt = new TcpClient();
Console.WriteLine("Connecting.....");
tcpclnt.Connect("127.0.0.1", 8020); // use the ipaddress as in the server program
Console.WriteLine("Connected");
Console.Write("Enter the string to be transmitted : ");
//gets the text from textbox
String str = textBox1.Text;
Stream stm = tcpclnt.GetStream();
ASCIIEncoding asen = new ASCIIEncoding();
byte[] ba = asen.GetBytes(str);
Console.WriteLine("Transmitting.....");
stm.Write(ba, 0, ba.Length);
byte[] bb = new byte[100];
int k = stm.Read(bb, 0, 100);
for (int i = 0; i < k; i++)
Console.Write(Convert.ToChar(bb[i]));
tcpclnt.Close();
}
catch (Exception ex)
{
Console.WriteLine("Error..... " + ex.StackTrace);
}
}
我正在使用一种表单在本地主机上进行通信并编写一个 .cs 文件,并希望将文本(来自文本框)从客户端标记部分显示到服务器标记部分的标签。
知道为什么它不显示输出吗?套接字新手!!!

也许它没有显示任何内容,因为您正在丢弃所有错误。
