方式一：

int delDir(const
char

{

if (NULL == pDir)	return -1;

char dir[MAX_PATH] = {0};

char fileName[MAX_PATH] = {0};

char *str = "\\*.*";

//首先查找dir中符合要求的文件

long hFile;

{

do

{

strcpy(fileName,pDir);

strcat(fileName,"\\");

strcat(fileName,fileinfo.name);

//检查是不是目录

//如果不是目录,则进行处理文件夹下面的文件

if (!(fileinfo.attrib & _A_SUBDIR))

{

remove(fileName);

}

else//处理目录，递归调用

{

if ( strcmp(fileinfo.name, "." ) != 0 && strcmp(fileinfo.name, ".." ) != 0 )

{

delDir(fileName);

//rmdir(fileName);

}

}

} while (_findnext(hFile,&fileinfo) == 0);

_findclose(hFile);

rmdir(pDir);

return 1;

}

return -3;

}

方式二：

//wchar_t wPath[MAX_PATH] = {0};

//wcstombs(path,wPath,MAX_PATH);//将宽字符转换成多字符

//mbstowcs(wPath,pDir,strlen(pDir));//把多字符把转换成宽字符

queue<wstring> DirQueue; // 用于删除文件

stack<wstring> DirStack; // 用于删除目录

if ( sRmDir.at( sRmDir.length() -1 ) != '\\' ||

sRmDir.at( sRmDir.length() -1 ) != '/' )

{

sRmDir += L"\\";

}

DirQueue.push( sRmDir );

DirStack.push( sRmDir );

//循环删除 目录中的文件

while ( !DirQueue.empty() )

{

wstring sFindDir;

sFindDir = DirQueue.front();

DirQueue.pop();

wstring sFindFirstFile;

sFindFirstFile = sFindDir;

sFindFirstFile += L"*";

HANDLE hFind = INVALID_HANDLE_VALUE;

WIN32_FIND_DATA Win32FindData;

hFind = FindFirstFile( sFindFirstFile.c_str(), &Win32FindData );

do

{

if ( hFind == INVALID_HANDLE_VALUE )

{

break;

}

else

{

wstring sFindFile;

sFindFile = sFindDir;

sFindFile += Win32FindData.cFileName;

if ( Win32FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY )

{

if ( wcscmp( Win32FindData.cFileName, L"." ) != 0 && wcscmp( Win32FindData.cFileName, L".." ) != 0 )

{

sFindFile += L"\\";

DirQueue.push( sFindFile );

DirStack.push( sFindFile );

}

}

    else

{

DeleteFile( sFindFile.c_str() );

}

}

} while ( FindNextFile( hFind, &Win32FindData ) );

if ( hFind != INVALID_HANDLE_VALUE )

{

FindClose( hFind );

hFind = INVALID_HANDLE_VALUE;

}

}

//删除目录

while ( !DirStack.empty() )

{

wstring sDir;

sDir = DirStack.top();

DirStack.pop();

RemoveDirectory( sDir.c_str() );

}

}

int main(int
argc,
char*

{

char szDir[ MAX_PATH ] = { 0 };

bool bRet = false;

std::cout << "please wait ...";
