C++ NamedPipeClientStream發送數據

Question

我想通過管道將數據從C++ DLL文件發送到C＃pip服務器。服務器已經編程，並且使用C＃客戶端可以正常獲取數據。

我簡單的C＃的客戶端代碼：

 System.IO.Pipes.NamedPipeClientStream pipeClient = new System.IO.Pipes.NamedPipeClientStream(".", "testpipe", System.IO.Pipes.PipeDirection.InOut, System.IO.Pipes.PipeOptions.None); 

     if (pipeClient.IsConnected != true) { pipeClient.Connect(); } 

     StreamReader sr = new StreamReader(pipeClient); 
     StreamWriter sw = new StreamWriter(pipeClient); 

      try 
      { 
       sw.WriteLine("Test Message"); 
       sw.Flush(); 
       pipeClient.Close(); 
      } 
      catch (Exception ex) { throw ex; } 
     } 

不過，我不來用C實現這一客戶端++。我需要哪些頭文件？ 你能給我一個簡單的例子嗎？謝謝！編輯： 感謝您的回覆！ 爲了測試它，我創建一個C++程序和編譯現在以下：

 #include "stdafx.h" 


int _tmain(int argc, _TCHAR* argv[]) 
{ 
HANDLE pipe = CreateFile(
    L"testpipe", 
    GENERIC_READ, // only need read access 
    FILE_SHARE_READ | FILE_SHARE_WRITE, 
    NULL, 
    OPEN_EXISTING, 
    FILE_ATTRIBUTE_NORMAL, 
    NULL 
); 

if (pipe == INVALID_HANDLE_VALUE) { 
    // look up error code here using GetLastError() 
    DWORD err = GetLastError(); 
    system("pause"); 
    return 1; 
} 


// The read operation will block until there is data to read 
wchar_t buffer[128]; 
DWORD numBytesRead = 0; 
BOOL result = ReadFile(
    pipe, 
    buffer, // the data from the pipe will be put here 
    127 * sizeof(wchar_t), // number of bytes allocated 
    &numBytesRead, // this will store number of bytes actually read 
    NULL // not using overlapped IO 
); 

if (result) { 
    buffer[numBytesRead/sizeof(wchar_t)] = '?'; // null terminate the string 
    // wcout << "Number of bytes read: " << numBytesRead << endl; 
    // wcout << "Message: " << buffer << endl; 
} else { 
    // wcout << "Failed to read data from the pipe." << endl; 
} 

// Close our pipe handle 
CloseHandle(pipe); 


system("pause"); 
return 0; 

return 0; 
} 

然而，當我運行它，所述（管== INVALID_HANDLE_VALUE）爲真。 調試顯示DWORD err = GetLastError（）;值爲2，儘管服務器正在運行。 有沒有人有想法？

你可以在網上找到很多例子。搜索命名管道示例C++。 例如：http://www.avid-insight.co.uk/2012/03/introduction-to-win32-named-pipes-cpp/
