Asp.net Socket客户端(远程发送和接收数据)

下面是"Asp.net Socket客户端(远程发送和接收数据)"的完整攻略：

1. 概述

Socket是实现网络通信的基本技术之一，它是支持TCP/IP协议的通信方式。现在越来越多的应用采用Socket技术来实现异步通信。在Asp.net开发中，我们可以利用Socket技术来实现异步客户端通信。

2. Socket客户端实现步骤

2.1 创建Socket

private Socket clientSocket;
clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

2.2 连接远程服务器

IPAddress ip = IPAddress.Parse("127.0.0.1"); //设置ip地址
IPEndPoint endpoint = new IPEndPoint(ip, 8888); //设置端口号
clientSocket.Connect(endpoint); //连接服务器

2.3 发送数据

byte[] data = Encoding.UTF8.GetBytes("Hello World！");
clientSocket.Send(data);

2.4 接收数据

byte[] data = new byte[1024];
int length = clientSocket.Receive(data);
string message = Encoding.UTF8.GetString(data, 0, length);

2.5 关闭Socket

clientSocket.Close(); //关闭Socket

3. 示例说明

3.1 示例1：实现与远程服务器的通信

private void Connect()
{
    //创建Socket
    clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    //设置ip地址和端口号
    IPAddress ip = IPAddress.Parse("127.0.0.1");
    IPEndPoint endpoint = new IPEndPoint(ip, 8888);
    //连接服务器
    try
    {
        clientSocket.Connect(endpoint);
    }
    catch(Exception e)
    {
        Console.WriteLine("连接服务器失败：" + e.Message);
        return;
    }
    Console.WriteLine("连接服务器成功！");
    //发送数据
    byte[] data = Encoding.UTF8.GetBytes("Hello World！");
    clientSocket.Send(data);
    Console.WriteLine("发送数据成功！");
    //接收数据
    data = new byte[1024];
    int length = clientSocket.Receive(data);
    string message = Encoding.UTF8.GetString(data, 0, length);
    Console.WriteLine("接收数据成功：" + message);
    //关闭Socket
    clientSocket.Close();
}

3.2 示例2：实现与多个远程服务器的通信

private void Connect()
{
    //创建Socket
    clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    //设置ip地址和端口号
    string[] ips = { "127.0.0.1", "192.168.1.100" };
    int[] ports = { 8888, 9999 };
    //连接多个服务器
    for(int i=0; i<ips.Length; i++)
    {
        try
        {
            IPAddress ip = IPAddress.Parse(ips[i]);
            IPEndPoint endpoint = new IPEndPoint(ip, ports[i]);
            clientSocket.Connect(endpoint);
            Console.WriteLine("连接服务器" + (i+1) + "成功！");
            //发送数据
            byte[] data = Encoding.UTF8.GetBytes("Hello World！");
            clientSocket.Send(data);
            Console.WriteLine("发送数据成功！");
            //接收数据
            data = new byte[1024];
            int length = clientSocket.Receive(data);
            string message = Encoding.UTF8.GetString(data, 0, length);
            Console.WriteLine("接收数据成功：" + message);
        }
        catch (Exception e)
        {
            Console.WriteLine("连接服务器" + (i + 1) + "失败：" + e.Message);
            continue;
        }
    }
    //关闭Socket
    clientSocket.Close();
}
