为什么RemoveDirectory功能不删除最顶层的文件夹？

Question

参考:codeguru.com/forum/showthread.php?t=239271

使用下面的功能删除文件夹时,除最顶层文件夹外,所有文件夹,子文件夹和文件都将被删除.说了路径c:\folder1\folder2的每一件事情下folder2被除删除folder2.

BOOL DeleteDirectory(const TCHAR* sPath)  
{  
    HANDLE hFind; // file handle
    WIN32_FIND_DATA FindFileData;

    TCHAR DirPath[MAX_PATH];
    TCHAR FileName[MAX_PATH];

    _tcscpy(DirPath,sPath);
    _tcscat(DirPath,_T("\\"));
    _tcscpy(FileName,sPath);
    _tcscat(FileName,_T("\\*")); // searching all files
    int nRet = 0;
    hFind = FindFirstFile(FileName, &FindFileData); // find the first file
    if( hFind != INVALID_HANDLE_VALUE ) 
    {
        do
        {
            if( IsDots(FindFileData.cFileName) ) 
                continue; //if not directory continue

            _tcscpy(FileName + _tcslen(DirPath), FindFileData.cFileName);
            if((FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) 
            {
                // we have found a directory, recurse
                if( !DeleteDirectory(FileName) ) 
                    break;   // directory couldn't be deleted
            }
            else 
            {
                if(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_READONLY)
                    _wchmod(FileName, _S_IWRITE); // change read-only file mode

                if( !DeleteFile(FileName) ) 
                    break;  // file couldn't be deleted
            }
        }while( FindNextFile(hFind, &FindFileData) );

        nRet = FindClose(hFind); // closing file handle
    }

    return RemoveDirectory(sPath); // remove the empty (maybe not) directory and returns zero when RemoveDirectory function fails
}  

任何帮助找到问题的人都表示赞赏.在调试期间,我注意到该FindClose函数已成功关闭文件句柄但GetLastError返回32("进程无法访问该文件,因为它正被另一个进程使用")但是我在尝试使用进程资源管理器后没有任何线索.

虽然您可以通过这种方式删除目录,但让系统通过调用SHFileOperation传递为您执行此操作更为简单FO_DELETE.请记住,必须对传递给此API的字符串进行双重null终止.
