android客户端与c#服务器端的通信

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();

}
