命名管道C＃服務器C++ .dll客戶端不能正常工作？

Question

所以我試圖使用命名管道在C＃服務器和我將注入的C++ .dll客戶端之間進行通信。 我的命名管道在與C++控制檯應用程序一起使用時工作正常，但是當我在.dll中使用相同的方法時，服務器和客戶端連接正常，但是當我嘗試使用NamedPipeServerStream.Write（）時，我的C＃應用​​程序凍結。如果這很重要，它們都是x64。

任何想法爲什麼？

C＃服務器

Thread ServerThread; 
    private static NamedPipeServerStream _server; 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     ServerThread = new Thread(ServerThreadSub); 

     ServerThread.Start(); 
    } 

    void ServerThreadSub() 
    { 
     while (true) 
     { 
      _server = new NamedPipeServerStream("ConsolePipe", PipeDirection.Out, 1, PipeTransmissionMode.Message); 
      _server.WaitForConnection(); 
      do 
      { 
      } while (_server.IsConnected); 
      _server.Close(); 
     } 
    } 

    private void text_CurrentCommand_KeyDown(object sender, KeyEventArgs e) 
    { 
     if (e.KeyCode == Keys.Return) 
     { 
      if (text_CurrentCommand.Text != "") 
      { 
       if (_server.IsConnected) 
       { 
        try 
        { 
         byte[] buff = Encoding.UTF8.GetBytes(text_CurrentCommand.Text); 
         _server.Write(buff, 0, buff.Length); //Freezes here 
        } 
        catch 
        { 
         Log("Client Disconnected, Command Not Processed."); 
        } 
       } 
       else 
       { 
        Log("Command Not Processed. Client Not Connected."); 
       } 
      } 
      e.SuppressKeyPress = true; 
     } 
    } 

C++客戶

#define PIPE_NAME L"\\\\.\\pipe\\ConsolePipe" 
#define BUFF_SIZE 1024 

HANDLE hPipe; 

DWORD WINAPI Main(LPVOID threadArgs) 
{ 
    while (true) 
    { 
     do 
     { 
      Sleep(1000); 
      hPipe = CreateFile(PIPE_NAME, GENERIC_READ, 0, nullptr, OPEN_EXISTING, 0, nullptr); 
      if (hPipe == NULL || hPipe == INVALID_HANDLE_VALUE) DeleteFile(PIPE_NAME); 
     } while (hPipe == NULL || hPipe == INVALID_HANDLE_VALUE); 

     DWORD mode = PIPE_READMODE_MESSAGE; 

     SetNamedPipeHandleState(hPipe, &mode, nullptr, nullptr); 

     bool success = false; 
     DWORD read; 

     while (true) 
     { 
      char chBuff[BUFF_SIZE]; 
      success = ReadFile(hPipe, chBuff, (DWORD)strlen(chBuff), &read, nullptr); 
      if (success) 
      { 
      } 
      if (!success) break; 
     } 
    } 
    return 0; 
} 

也是另一個查詢我是不是真的很重要，有沒有什麼辦法讓NamedPipeServerStream.IsConnected無需執行讀取刷新（ ）或寫（）？

在此先感謝C：

如果要創建一個dll那麼我建議你使用DllMain()作爲入門點，這可能是一個主要的原因你的程序無法正常工作

BOOL WINAPI DllMain(
    HINSTANCE hinstDLL, // handle to DLL module 
    DWORD fdwReason,  // reason for calling function 
    LPVOID lpReserved) // reserved 
{ 
    // Perform actions based on the reason for calling. 
    switch(fdwReason) 
    { 
     case DLL_PROCESS_ATTACH: 
     // Initialize once for each new process. 
     // Return FALSE to fail DLL load. 
      break; 

     case DLL_THREAD_ATTACH: 
     // Do thread-specific initialization. 
      break; 

     case DLL_THREAD_DETACH: 
     // Do thread-specific cleanup. 
      break; 

     case DLL_PROCESS_DETACH: 
     // Perform any necessary cleanup. 
      break; 
    } 
    return TRUE; // Successful DLL_PROCESS_ATTACH. 
}
