In C#, you can specify the client to send information using the Send method of the Socket object. Here is a simple example code:

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

class Program
{
    static void Main()
    {
        // 创建一个Socket对象
        Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

        // 连接到服务器
        socket.Connect("127.0.0.1", 8888);

        // 发送消息给服务器
        string message = "Hello, server!";
        byte[] data = Encoding.ASCII.GetBytes(message);
        socket.Send(data);

        // 关闭Socket连接
        socket.Shutdown(SocketShutdown.Both);
        socket.Close();
    }
}

In the example above, a Socket object is first created and connected to the server’s IP address and port number. Then, the message to be sent is converted to a byte array and sent to the server using the Send method. Finally, the Socket connection is closed.
