visual在C++中使用ReadFIle(）函数时无法从文件中读取

我在使用C++的ReadFile（）函数从文件中读取数据时遇到了一些问题（可能是Microsoft特有的）。

这是我的代码

写入文件

void ClientA::SharePublicKey()
{
    printf("Sharing Public Keyn");
    HANDLE hFile = NULL;
    hFile = CreateFile(TEXT("D:\My_Proj\shared\PublicKeyB.txt"),                // name of the write
                       GENERIC_WRITE,          // open for writing
                       FILE_SHARE_WRITE,                      // do not share
                       NULL,                   // default security
                       CREATE_NEW,             // create new file only
                       FILE_ATTRIBUTE_NORMAL,  // normal file
                       NULL);                  // no attr. template
    if (hFile == INVALID_HANDLE_VALUE) 
    { 
        //DisplayError(TEXT("CreateFile"));
        //_tprintf(TEXT("Terminal failure: Unable to open file "%s" for write.n"), argv[1]);
        return;
    }
   // _tprintf(TEXT("Writing %d bytes to %s.n"), dwBytesToWrite, argv[1]);
    bool bErrorFlag = WriteFile( 
                    hFile,           // open file handle
                    pbPublicKey,      // start of data to write
                    dwPublicKeyLen,  // number of bytes to write
                    &lpNumberOfBytesWritten, // number of bytes that were written
                    NULL);            // no overlapped structure
    if (FALSE == bErrorFlag)
    {
       // DisplayError(TEXT("WriteFile"));
        printf("Terminal failure: Unable to write to file.n");
        return;
    }
    else
    {
        if (lpNumberOfBytesWritten != dwPublicKeyLen)
        {
            // This is an error because a synchronous write that results in
            // success (WriteFile returns TRUE) should write all data as
            // requested. This would not necessarily be the case for
            // asynchronous writes.
            printf("Error: dwBytesWritten != dwBytesToWriten");
        }
        else
        {
          //  _tprintf(TEXT("Wrote %d bytes to %s successfully.n"), dwBytesWritten, argv[1]);
        }
    }
    CloseHandle(hFile);
}

读取该文件

void ClientA::ReadPublicKeyOfOtherPeer()
{
    HANDLE hFile = NULL; 
    DWORD  dwBytesRead = 0;
    BYTE*   ReadBuffer = NULL;
    OVERLAPPED ol = {0};

    hFile = CreateFile(TEXT("D:\My_Proj\shared\PublicKeyB.txt"),               // file to open
                        GENERIC_READ,          // open for reading
                       FILE_SHARE_READ,       // share for reading
                       NULL,                  // default security
                       OPEN_EXISTING,         // existing file only
                       FILE_ATTRIBUTE_NORMAL | FILE_FLAG_OVERLAPPED, // normal file
                       NULL                 // no attr. template
                       );
    if (hFile == INVALID_HANDLE_VALUE) 
    { 
        _tprintf(TEXT("CreateFilen"));
        _tprintf(TEXT("Terminal failure: unable to open file "%s" for read.n"));
        printf("Error %xn", GetLastError());
        return; 
    }

    if( FALSE == ReadFile(hFile, ReadBuffer, dwPublicKeyLen, &lpNumberOfBytesWritten, &ol) )
    {
       // DisplayError(TEXT("ReadFile"));
        printf("Terminal failure: Unable to read from file.n GetLastError=%08xn", GetLastError());
        CloseHandle(hFile);
        return;
    }

    if (dwBytesRead > 0 && dwBytesRead <= dwPublicKeyLen-1)
    {
        ReadBuffer[dwBytesRead]=''; // NULL character
        //_tprintf(TEXT("Data read from %s (%d bytes): n"), argv[1], dwBytesRead);
        printf("%sn", ReadBuffer);
    }
    else if (dwBytesRead == 0)
    {
        //_tprintf(TEXT("No data read from file %sn"), argv[1]);
    }
    else
    {
       // printf("n ** Unexpected value for dwBytesRead ** n");
    }
    retrievedPublicByteArray = ReadBuffer;


    CloseHandle(hFile);
}

通过SharePublicKey方法，我将数据保存在一个文件中。我已经检查了它是否成功地将数据保存在文件上，并且文件上的数据似乎是有效的。

通过ReadPublicKeyOfOtherPeer方法，我正在读取以前保存的文件。但是阅读不成功输入输出我发现了以下行-

终端故障：无法从文件中读取。GetLastError=000003e6
