用C++建立客户端Socket，怎么用C#建立服务器端Socket进行通信，C++发数据，C#收数据。请给出示例代码。

#include <winsock2.h>
#include <stdio.h>
#include <stdlib.h>#pragma comment(lib, "Ws2_32.lib")#define DEFAULT_BUFLEN 4096
#define DEFAULT_PORT 8000int main(int argc, char* argv[])
{if(argc == 1){printf("Please Input the Address of Input File!\n");return 0;} //Buffersint recvbuflen = DEFAULT_BUFLEN;char sendbuf[DEFAULT_BUFLEN];char recvbuf[DEFAULT_BUFLEN] = "";//FILE FILE* file = fopen("C:/1.txt", "rb");if(file == NULL){printf("Failed to open Input File!\n");return 0 ;}while(1){//SOCKET//----------------------// Declare and initialize variables.int iResult;WSADATA wsaData;// Initialize WinsockiResult = WSAStartup(MAKEWORD(1,1), &wsaData);if (iResult != NO_ERROR){printf("WSAStartup failed with error: %d\n", iResult);return 1;}SOCKET ConnectSocket;struct sockaddr_in clientService; // Create a SOCKET for connecting to serverConnectSocket = socket(AF_INET, SOCK_STREAM, 0)  ;if (ConnectSocket == INVALID_SOCKET){printf("socket failed with error: %ld\n", WSAGetLastError());WSACleanup();continue;}//----------------------// The sockaddr_in structure specifies the address family,// IP address, and port of the server to be connected to.clientService.sin_family = AF_INET;clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );clientService.sin_port = htons( DEFAULT_PORT );//----------------------// Connect to server.iResult = connect( ConnectSocket, (SOCKADDR*) &clientService, sizeof(clientService) ) ; if (iResult == SOCKET_ERROR) {printf( "connect failed with error: %d\n", WSAGetLastError() );closesocket(ConnectSocket);WSACleanup();continue;}while(1){fread(sendbuf, DEFAULT_BUFLEN,  sizeof(char), file);if(feof(file)){printf("Reading to the end of input file, seek to the beginning of File!\n");fseek(file, 0, SEEK_SET);}//----------------------// Send an initial bufferiResult = send( ConnectSocket, sendbuf, DEFAULT_BUFLEN, 0 );if (iResult == SOCKET_ERROR) {printf("send() failed with error: %d\n", WSAGetLastError());closesocket(ConnectSocket);WSACleanup();break;}else{printf("Send package size = %d \n", iResult);}}if (iResult == SOCKET_ERROR) {continue;}// shutdown the connection since no more data will be sentiResult = shutdown(ConnectSocket, SD_SEND);if (iResult == SOCKET_ERROR) {printf("shutdown failed with error: %d\n", WSAGetLastError());closesocket(ConnectSocket);WSACleanup();return 1;}// cleanupclosesocket(ConnectSocket);WSACleanup();}return 0 ;}

TcpListener进行监听就可以了。
using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text;class MyTcpListener
{public static void Main(){ TcpListener server=null;   try{// Set the TcpListener on port 13000.Int32 port = 8000;IPAddress localAddr = IPAddress.Parse("127.0.0.1");// TcpListener server = new TcpListener(port);server = new TcpListener(localAddr, port);// Start listening for client requests.server.Start();// Buffer for reading dataByte[] bytes = new Byte[4096];String data = null;// Enter the listening loop.while(true) {Console.Write("Waiting for a connection... ");// Perform a blocking call to accept requests.// You could also user server.AcceptSocket() here.TcpClient client = server.AcceptTcpClient();            Console.WriteLine("Connected!");data = null;// Get a stream object for reading and writingNetworkStream stream = client.GetStream();int i;// Loop to receive all the data sent by the client.while((i = stream.Read(bytes, 0, bytes.Length))!=0) {   // Translate data bytes to a ASCII string.data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);Console.WriteLine("Received: {0}", data);// Process the data sent by the client.data = data.ToUpper();byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);// Send back a response.stream.Write(msg, 0, msg.Length);Console.WriteLine("Sent: {0}", data);            }// Shutdown and end connectionclient.Close();}}catch(SocketException e){Console.WriteLine("SocketException: {0}", e);}finally{// Stop listening for new clients.server.Stop();}Console.WriteLine("\nHit enter to continue...");Console.Read();}
}当然，官方的这个示例是单线程的，一次只能处理一个客户端，你可以将accept到的client扔到一个独立的线程，这样就可以多客户端并发处理了。
