服务端代码：

// pipe_server.cpp : 定义控制台应用程序的入口点。// #include "stdafx.h"#include <stdio.h>#include <windows.h>#include <ctime> int main(int argc, _TCHAR* argv[]){ srand(time(NULL)); char buf[256] = ""; DWORD rlen = 0; HANDLE hPipe = CreateNamedPipe( TEXT("\\\\.\\Pipe\\mypipe"), //管道名 PIPE_ACCESS_DUPLEX, //管道类型 PIPE_TYPE_MESSAGE|PIPE_READMODE_MESSAGE|PIPE_WAIT, //管道参数 PIPE_UNLIMITED_INSTANCES, //管道能创建的最大实例数量 0, //输出缓冲区长度 0表示默认 0, //输入缓冲区长度 0表示默认 NMPWAIT_WAIT_FOREVER, //超时时间 NULL); //指定一个SECURITY_ATTRIBUTES结构,或者传递零值 if (INVALID_HANDLE_VALUE == hPipe) { printf("Create Pipe Error(%d)\n",GetLastError()); } else { printf("Waiting For Client Connection...\n"); if(!ConnectNamedPipe(hPipe, NULL)) //阻塞等待客户端连接。 { printf("Connection failed!\n"); } else { printf("Connection Success!\n"); } while (true) { if(!ReadFile(hPipe,buf,256,&rlen,NULL)) //接受客户端发送过来的内容 { printf("Read Data From Pipe Failed!\n"); break; } else { printf("From Client: data = %s, size = %d\n", buf, rlen); char wbuf[256] = ""; sprintf(wbuf, "%s%d", wbuf, rand()%1000); DWORD wlen = 0; WriteFile(hPipe, wbuf, sizeof(wbuf), &wlen, 0); //向客户端发送内容 printf("To Client: data = %s, size = %d\n", wbuf, wlen); Sleep(1000); } } FlushFileBuffers(hPipe); DisconnectNamedPipe(hPipe); CloseHandle(hPipe);//关闭管道 } system("pause"); return 0;}

客户端代码：
