C#：如何通过SocketAsyncEventArgs发送非托管内存？

using System;
using System.Net.Sockets;

public class SocketExample
{
    private Socket socket;
    private SocketAsyncEventArgs sendEventArgs;

    public SocketExample()
    {
        socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        sendEventArgs = new SocketAsyncEventArgs();
        sendEventArgs.Completed += SendCompleted;
    }

    public void SendUnmanagedMemory(IntPtr unmanagedMemory, int offset, int count)
    {
        sendEventArgs.SetBuffer(unmanagedMemory, offset, count);
        socket.SendAsync(sendEventArgs);
    }

    private void SendCompleted(object sender, SocketAsyncEventArgs e)
    {
        // 处理发送完成的逻辑
    }
}
