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();
}
