您能否在System.Net.Sockets中设置接收呼叫，使其行为类似于设置了MSG_PUSH_IMMEDIATE标志的winsocket2 WSARecv

using System;
using System.Net;
using System.Net.Sockets;
using System.Threading;

class Program
{
    private static Socket socket;
    private static byte[] buffer = new byte[1024];

    static void Main(string[] args)
    {
        socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        socket.Bind(new IPEndPoint(IPAddress.Any, 1234));
        socket.Listen(10);

        // 开始异步接收
        socket.BeginAccept(new AsyncCallback(AcceptCallback), null);

        Console.WriteLine("等待客户端连接...");
        Thread.Sleep(Timeout.Infinite);
    }

    private static void AcceptCallback(IAsyncResult result)
    {
        // 客户端连接成功，开始异步接收数据
        Socket clientSocket = socket.EndAccept(result);
        clientSocket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), clientSocket);

        Console.WriteLine("客户端已连接，开始接收数据...");
    }

    private static void ReceiveCallback(IAsyncResult result)
    {
        Socket clientSocket = (Socket)result.AsyncState;
        int bytesRead = clientSocket.EndReceive(result);

        // 处理接收到的数据
        if (bytesRead > 0)
        {
            byte[] receivedData = new byte[bytesRead];
            Buffer.BlockCopy(buffer, 0, receivedData, 0, bytesRead);

            Console.WriteLine("接收到数据：{0}", Encoding.Default.GetString(receivedData));

            // 继续异步接收
            clientSocket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), clientSocket);
        }
    }
}
