1.引入Sockets
using System.Net.Sockets;
2.定义TcpClient
private TcpClient tcpClient; // TcpClient实例
private NetworkStream stream; // 网络流，用于与服务器通信
3.连接网口
tcpClient = new TcpClient(); // TcpClient实例
{
try
{
tcpClient.Connect("IP地址", "端口号");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
4.发送数据
byte[] b = Encoding.ASCII.GetBytes(liens);
stream = tcpClient.GetStream();
BinaryWriter writer = new BinaryWriter(stream);//写入流
writer.Write(b, 0, b.Length);
5.关闭连接
tcpClient.Close();
