Stream Socket通常用于传输一些比较长的数据,如文件。但这里为了使演示变得更容易理解,我传输了一段字符。
首先,我们用WinForm做一个服务器端。界面不复杂,目的是侦听连接,收到传入的客户端连接后,向客户端发送一条字符串消息。

处理的逻辑代码如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO;
using System.Net;
using System.Net.Sockets;
namespace TestServerApp
{
public partial class Form1 : Form
{
TcpListener m_Listener = null;//用于监听链接
TcpClient m_Client = null;//传入的客户端
public Form1()
{
InitializeComponent();
this.btnStart.Enabled = true;
this.btnStop.Enabled = false;
}
/// <summary>
/// 向客户端发送字符串
/// </summary>
private void SendMessage(TcpClient client)
{
using (var stream = client.GetStream())
{
byte[] buffer = Encoding.UTF8.GetBytes("奔,不停地奔,奔向传说中的荒原;飞,不停地飞,飞向天空的那一端。");
uint len = (uint)buffer.Length;
// 先发送长度
stream.Write(BitConverter.GetBytes(len), 0, sizeof(uint));
// 再发送数据
stream.Write(buffer, 0, buffer.Length);
}
}
private async void btnStart_Click(object sender, EventArgs e)
{
if (this.m_Listener == null)
{
this.m_Listener = new TcpListener(IPAddress.Parse(this.txtAddr.Text), Convert.ToInt32(this.udPort.Value));
}
this.m_Listener.Start();
this.lblMsg.Text = "监听已开始。";
this.btnStart.Enabled = false;
this.btnStop.Enabled = true;
try
{
m_Client = await m_Listener.AcceptTcpClientAsync();
SendMessage(m_Client);
}
catch (SocketException se)
{
this.lblMsg.Text = se.Message;
}
catch (Exception ex)
{
this.lblMsg.Text = ex.Message;
}
}
private void btnStop_Click(object sender, EventArgs e)
{
if (m_Listener != null)
{
m_Listener.Stop();
this.lblMsg.Text = "监听已停止。";
}
this.btnStart.Enabled = true;
this.btnStop.Enabled = false;
}
}
}
接着是Win8 App客户端。
因为我们要使用网络连接,在创建项目后,把开清单文件,切换到【功能】选项卡,把和网络连接有关的选项勾上。

打开主页MainPage的XAML代码编辑器(设计视图),简单布局一下界面。
