C# Socket Server
1.建立C# SocketServer
1 private void ServerStart()
2 {
3 //创建IPEndPoint
4 IPEndPoint ipep = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 1234);
5 //创建Socket实例
6 server_Socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
7 //绑定Socket与IPEndPoint
8 server_Socket.Bind(ipep);
9 //设置Socket收听模式
10 server_Socket.Listen(10);
11
12 while (true)
13 {
14 try
15 {
16 //接受Andorid信息
17 client_Socket = server_Socket.Accept();
18 client_Thread = new Thread(new ThreadStart(ReceiveAndroidData));
19 client_Thread.Start();
20 }
21 catch (Exception ex)
22 {
23 MessageBox.Show("start error: " + ex.Message);
24 }
25
26 }
27 }
2.开启一个Theard，执行
1 server_Thread = new Thread(new ThreadStart(ServerStart));
2 server_Thread.Start();
3.介绍方法
private void ReceiveAndroidData()
{
bool keepalive = true;
Socket socketclient = client_Socket;
Byte[] buffer = new Byte[1024];
//根据收听到的客户端套接字向客户端发送信息
IPEndPoint clientep = (IPEndPoint)socketclient.RemoteEndPoint;
lstServer.Items.Add("Andorid Client：" + clientep.Address + "："+clientep.Port);
string str = "connect server----- ";
byte[] data = new byte[1024];
data = Encoding.ASCII.GetBytes(str);
socketclient.Send(data, data.Length, SocketFlags.None);
while (keepalive)
{
//在套接字上接收客户端发送的信息
int buffer_lenght = 0;
try
{
buffer_lenght = socketclient.Available;
socketclient.Receive(buffer, 0, buffer_lenght, SocketFlags.None);
if (buffer_lenght == 0)
continue;
}
catch (Exception ex)
{
MessageBox.Show("receive error:" + ex.Message);
return;
}
clientep = (IPEndPoint)socketclient.RemoteEndPoint;
string strAndroid_CMD = System.Text.Encoding.ASCII.GetString(buffer).Substring(0, buffer_lenght);
//对根据strAndroid_CMD到数据库中查询值
Android Client：
1. OnCreate方法中执行
try {
Socket socket = new Socket("10.0.2.2", 1234);
PrintWriter out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(socket.getOutputStream())), true);
out.println(cameraid);
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
代码很就简单
==================================
需要注意的是：
1.添加internet访问权限：<uses-permission android:name="android.permission.INTERNET" />。
2.127.0.0.1 IP被模拟器占用了，而本身PC的IP为10.0.2.2，如果本机测试的时候需要注意这一点。
