递归删除文件夹的问题

[shaw0129]

一个零时文件夹，文件夹里面又有文件夹和文件，在处理结束后要删除，我就递归先删除里面的，然后再删外面的，可是出现 145 error code 的错误，文件夹删除不掉. 不知道什么原因，高手指点下。

查了RemoveDirectory 难道是有文件夹被打开了句柄 没有被关掉？ 如果是这样的话怎么找出来呢？

bool ForceRemoveDirectory(LPCTSTR szName )
{

HANDLE findHandle = ::FindFirstFile(csPattern, &finddata);
DWORD dwError;

if(findHandle == INVALID_HANDLE_VALUE)
{
dwError = ::GetLastError();

if((dwError == ERROR_FILE_NOT_FOUND) || (dwError == ERROR_PATH_NOT_FOUND))
{
::SetLastError(NO_ERROR);
}
else
{

return false;
}
}
else
{


do
{

if(CString(finddata.cFileName) == _T(".") || (CString(finddata.cFileName) == _T(".."))
continue;

CString csPath = szName + filename[nameindex];

if(finddata.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
ForceRemoveDirectory(csPath, &csErrorFileTemp[nameindex]);
}
else
{
DeleteFile(csPath);
}
}
}

} while(::FindNextFile(findHandle, &finddata));

if(!::RemoveDirectory(szName))
{

dwError = ::GetLastError();

if((dwError == ERROR_FILE_NOT_FOUND)||(dwError == ERROR_PATH_NOT_FOUND))
{
::SetLastError(NO_ERROR);
return true;
}

return false;
}
return true;
}

现成的函数，整个删不行吗？

用SHFileOperation

145 目录不是空的。

[stonewater]

The RemoveDirectory function marks a directory for deletion on close. Therefore, the directory is not removed until the last handle to the directory is closed.

To recursively delete the files in a directory, use the SHFileOperation function.

这是我写的，你可以参考一下

//删除指定文件夹
bool CYourClass::DeleteFolder(wchar_t* pwcPath )
{
    if(pwcPath == NULL)
        return false;

    wchar_t wcPath[MAX_PATH] = {0};
    wcscpy_s(wcPath,MAX_PATH,pwcPath);
    wcscat_s(wcPath,MAX_PATH,_T("\\*.*"));
    WIN32_FIND_DATA FindFileData;
    ZeroMemory(&FindFileData,sizeof(WIN32_FIND_DATA));

    HANDLE hFindFile = FindFirstFile(wcPath,&FindFileData);

    if(hFindFile == INVALID_HANDLE_VALUE)
        return false;

    BOOL bContinue = true;

    while (bContinue != false)
    {
        //bIsDots为真表示是.或..
        bool bIsDots = (wcscmp(FindFileData.cFileName,_T(".")) == 0 || wcscmp(FindFileData.cFileName,_T("..")) == 0);
        if ((FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) != 0 && bIsDots == false)
        {
            //是目录,就再进入该目录
            wcscpy_s(wcPath,MAX_PATH,pwcPath);
            wcscat_s(wcPath,MAX_PATH,_T("\\"));
            wcscat_s(wcPath,MAX_PATH,FindFileData.cFileName);
            DeleteFolder(wcPath);
            //寻找下一文件
            bContinue = FindNextFile(hFindFile,&FindFileData);
            continue;
        }

        if (bIsDots == false)
        {
            //是文件删除之
            wcscpy_s(wcPath,MAX_PATH,pwcPath);
            wcscat_s(wcPath,MAX_PATH,_T("\\"));
            wcscat_s(wcPath,MAX_PATH,FindFileData.cFileName);
            DeleteFile(wcPath);
        }
        //寻找下一文件
        bContinue = FindNextFile(hFindFile,&FindFileData);

    }

    FindClose(hFindFile);

    //删除空目录
    RemoveDirectory(pwcPath);
    return true;
}
