1,首先添加兩個windows窗體項目,一個做爲服務端server,一個做爲客戶端Client
2,而後添加服務端代碼,添加命名空間,界面上添加TextBox控件
using System.Net;
using System.Net.Sockets;
3,FormLoad方法添加代碼
private void Form1_Load(object sender, EventArgs e)
{
IPEndPoint epServer = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 7878);//IP地址和端口號
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//定義socket
socket.Bind(epServer);//綁定
socket.Listen(10);//監聽
socket.BeginAccept(new AsyncCallback(RecVing), socket);//異步接收,回調方法爲RecVing
}
4,添加回調方法代碼
private void RecVing(IAsyncResult rec_socket)
{
string cmdstr = "";
Socket sc = (Socket)rec_socket.AsyncState;
Socket socket = sc.EndAccept(rec_socket);
byte[] bytes = new byte[1024];
int i = socket.Receive(bytes);
cmdstr = Encoding.UTF8.GetString(bytes, 0, i);
showstrs(cmdstr);
sc.BeginAccept(new AsyncCallback(RecVing), sc);
}
5,添加showstrs方法,
定義委託private delegate void shixudong_invoke(string invokefun);
private void showstrs(string recv_strs)
{
if (recv_strs.Length != 0)
{
if (this.InvokeRequired)
{
shixudong_invoke invoke = new shixudong_invoke(showstrs);
this.Invoke(invoke, (object)recv_strs);
}
else
{
textBox1.Text = recv_strs;
}
}
}
6,到此爲止,服務端已經添加完畢
7,客戶端代碼,首先跟服務端同樣,添加命名空間,在界面上添加button事件
private void button1_Click(object sender, EventArgs e)
{
IPEndPoint IPEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 7878);//IP,端口號
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.BeginConnect(IPEndPoint, new AsyncCallback(Sending), socket);//回調方法Sending
}
8,添加回調方法,代碼以下
private void Sending(IAsyncResult rec_socket)
{
Socket socket = (Socket)rec_socket.AsyncState;
try託福答案
{
if (socket.Connected)
{
byte[] msgBuff = Encoding.UTF8.GetBytes(textBox1.Text);
socket.Send(msgBuff);
//socket.Accept();
}
else
{
Console.WriteLine("Error!", "Error!");
}
}
catch
{
Console.WriteLine("Error!", "Error!");
}
}
9,到此爲止,客戶端代碼已經完成,調試的時候先啓動服務端,而後啓動客戶端windows
