Windows Phone 7 网络编程之使用Socket（芒果更新）
芒果更新的Windows Phone 7.1版本的API提供了Socket编程的接口，这给Windows Phone 7的网络开发又添加了一把利器，对于Windows Phone 7上的聊天软件开发是一件非常happy的事情。下面用一个小例子来演示一下Windows Phone 7上的Socket编程。用Windows Phone 7上的客户端程序作为Socket客户端，Windows控制台程序作为服务器端，ip取你电脑本机的ip，端口号用8888，实现了Windows Phone 7客户端向服务器端发送消息和接收消息的功能。
先来看看演示的效果
（1） Windows Phone 7客户端客户端的实现。

using System.Linq;

using System.Threading;
namespace SocketServer
{
static class Program
{
private static AutoResetEvent _flipFlop = new AutoResetEvent(false);
static void Main(string[] args)
{
//创建socket，使用的是TCP协议，如果用UDP协议，则要用SocketType.Dgram类型的Socket
Socket listener = new Socket(AddressFamily.InterNetwork,
SocketType.Stream,
ProtocolType.Tcp);
//创建终结点EndPoint 取当前主机的ip
IPHostEntry ipHostInfo = Dns.Resolve(Dns.GetHostName());
//把ip和端口转化为IPEndpoint实例,端口号取8888
IPEndPoint localEP = new IPEndPoint(ipHostInfo.AddressList.First(), 8888);
Console.WriteLine("本地的IP地址和端口是 : {0}", localEP);
try
{
//绑定EndPoint对像（8888端口和ip地址）
listener.Bind(localEP);
//开始监听
listener.Listen(10);
//一直循环接收客户端的消息
while (true)
{
Console.WriteLine("等待Windows Phone客户端的连接...");
//开始接收下一个连接
listener.BeginAccept(AcceptCallback, listener);
//开始线程等待
_flipFlop.WaitOne();
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
/// <summary>
/// 接收返回事件处理
/// </summary>
/// <param name="ar"></param>
private static void AcceptCallback(IAsyncResult ar)
{
Socket listener = (Socket)ar.AsyncState;
Socket socket = listener.EndAccept(ar);
Console.WriteLine("连接到Windows Phone客户端。");
_flipFlop.Set();
//开始接收，传递StateObject对象过去
var state = new StateObject();
state.Socket = socket;
socket.BeginReceive(state.Buffer,
0,
StateObject.BufferSize,
0,
ReceiveCallback,
state);
}
private static void ReceiveCallback(IAsyncResult ar)
{
StateObject state = (StateObject)ar.AsyncState;
Socket socket = state.Socket;
// 读取客户端socket发送过来的数据
int read = socket.EndReceive(ar);
// 如果成功读取了客户端socket发送过来的数据
if (read > 0)
{
//获取客户端的消息，转化为字符串格式
string chunk = Encoding.UTF8.GetString(state.Buffer, 0, read);
state.StringBuilder.Append(chunk);
if (state.StringBuilder.Length > 0)
{
string result = state.StringBuilder.ToString();
Console.WriteLine("收到客户端传过来的消息: {0}", result);
//发送数据信息给客户端
Send(socket, result);
}
}
}
/// <summary>

/// </summary>
/// <param name="handler"></param>
/// <param name="data"></param>
private static void Send(Socket handler, String data)
{
//将消息内容转化为发送的byte[]格式
byte[] byteData = Encoding.UTF8.GetBytes(data);
//发送消息到Windows Phone客户端
handler.BeginSend(byteData, 0, byteData.Length, 0,
new AsyncCallback(SendCallback), handler);
}
private static void SendCallback(IAsyncResult ar)
{
try
{
Socket handler = (Socket)ar.AsyncState;
// 完成发送消息到Windows Phone客户端
int bytesSent = handler.EndSend(ar);
if (bytesSent > 0)
{
Console.WriteLine("发送成功！");
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
public class StateObject
{
public Socket Socket;
public StringBuilder StringBuilder = new StringBuilder();
public const int BufferSize = 10;
public byte[] Buffer = new byte[BufferSize];
public int TotalSize;
}
}
ok了。。。晚安！
