递归创建目录1:
需要#include <shlwapi.h>,并且配置好shlwapi.ib
BOOL CreateDirTree( LPCTSTR lpPath )
{if( NULL == lpPath || _tcslen(lpPath)==0)
{returnFALSE;
}if( ::PathFileExists( lpPath) ||::PathIsRoot(lpPath) )returnTRUE;
TCHAR szParentpath[MAX_PATH]= _T("");
::lstrcpy( szParentpath, lpPath );
::PathRemoveBackslash( szParentpath );//去除路径最后的反斜杠
::PathRemoveFileSpec( szParentpath );//将路径末尾的文件名或文件夹和反斜杠去掉
if(0 ==_tcscmp(lpPath, szParentpath))returnFALSE;
assert(0 !=_tcscmp(lpPath, szParentpath));if( CreateDirTree( szParentpath) )//递归创建直到上一层存在或是根目录
{return::CreateDirectory(lpPath, NULL);
}else{returnFALSE;
}returnTRUE;
}
递归创建目录2:
void __fastcall RecursiveDirectory(CString cstrDir) //递归创建目录
{if (cstrDir.GetLength() <= 3)//是根目录,无需创建目录
{return;
}if (cstrDir[cstrDir.GetLength()-1] == '\\') //将路径改为目录
{
cstrDir.Delete(cstrDir.GetLength()-1, 1);
}//修改文件属性
WIN32_FIND_DATA wfd;
HANDLE hFind= FindFirstFile(cstrDir, &wfd); //查找
if (hFind !=INVALID_HANDLE_VALUE)
{
FindClose(hFind);if (wfd.dwFileAttributes &FILE_ATTRIBUTE_DIRECTORY)return;
}//创建当前目录的地目录失败
if (CreateDirectory(cstrDir,NULL) == false)
{//退到上一级目录
CString wstrNewDir =cstrDir;int n = wstrNewDir.ReverseFind('\\');
wstrNewDir=cstrDir.Left(n);//递归进入
RecursiveDirectory(wstrNewDir); //递归本函数,再创建目录//递归退出后创建之前失败的目录
CreateDirectory(cstrDir,NULL); //递归返回,在存在的目录上再建目录
}//多级目录创建成功
}
递归创建目录3:
BOOL RecursiveDirectory(wstring wstrDir)
{if (wstrDir.length() <= 3)
{returnFALSE;
}if (wstrDir[wstrDir.length() - 1] == '\\')
{
wstrDir.erase(wstrDir.end()- 1);
}if(PathFileExists(wstrDir.c_str()))returnTRUE;if (CreateDirectory(wstrDir.c_str(), NULL) == false)
{
wstring wstrNewDir=wstrDir;while (wstrNewDir[wstrNewDir.length() - 1] != '\\')
{
wstrNewDir.erase(wstrNewDir.length()- 1);
}//delete '\\'
wstrNewDir.erase(wstrNewDir.length() - 1);
RecursiveDirectory(wstrNewDir);
CreateDirectory(wstrDir.c_str(), NULL);
}if (!PathFileExists(wstrDir.c_str()))returnFALSE;returnTRUE;
}
递归创建目录4:
bool createDirectory(const char*pathName)
{charpath[MAX_PATH];
memset(path,0x00, MAX_PATH);const char* pos =pathName;while ((pos = strchr(pos, '\\')) !=NULL)
{
memcpy(path, pathName, pos- pathName + 1);
pos++;if (_access(path, 0) == 0)
{continue;
}else{int ret =_mkdir(path);if (ret == -1)
{return false;
}
}
}return true;
}
递归删除目录1:
system("rmdir /s /q dirname"); //dirname是要删除的目录名称,这种方式,在使用MFC程序的时候出闪过一个CMD的窗口
/s是级联删除 /q 是不提示(在命令行下操作的话,如果不加这个开关,会有提示确认是否删除目录,而在程序中不允许停下)
递归删除目录2:
SHFILEOPSTRUCT FileOp;
FileOp.fFlags=FOF_NOCONFIRMATION;
FileOp.hNameMappings=NULL;
FileOp.hwnd=NULL;
FileOp.lpszProgressTitle=NULL;
FileOp.pFrom= ".\\tempDir";
FileOp.pTo=NULL;
FileOp.wFunc=FO_DELETE;
SHFileOperation(&FileOp);
此处有一个地方要留心一下,就是FileOp.pFrom这个参数,它使用的字符串一定是要'\0'结尾的,这个地方使用".\\tempDir",这个字符串默认的结束字符就是'\0',所以如果存在这个目录或者文件的话,一定可以将其删除,如果像下面这样写的话就会出错:
std::string delPath = ".\\tempDir";
FileOp.pFrom = delPath.c_str();
递归删除目录3:
bool deleteDirectory( char*pathName)
{struct_finddata_t fData;
memset(&fData, 0, sizeof(fData));if (_chdir(pathName) != 0) //_chdir函数设置当前目录
{
printf("chdir failed: %s\n",pathName);return false;
}
intptr_t hFile= _findfirst("*",&fData); //参数1:char *类型,"*"表示通配符,可以查找文件、文件夹
if(hFile == -1)
{
printf("_findfirst error!\n");return false;
}do{if(fData.name[0] == '.')continue;if(fData.attrib == _A_SUBDIR) //子文件夹
{chardirPath[MAX_PATH];
memset(dirPath,0,sizeof(pathName));
strcpy_s(dirPath,pathName);
strcat_s(dirPath,"\\");
strcat_s(dirPath,fData.name);
deleteDirectory(dirPath);//recursion subdir
printf("remove dir: %s\n",dirPath);
_chdir("..");
_rmdir(dirPath);
}else{charfilePath[MAX_PATH];
memset(filePath,0,sizeof(filePath));
strcpy_s(filePath,pathName);
strcat_s(filePath,"\\");
strcat_s(filePath,fData.name);
remove(filePath);
printf("remove file: %s\n",filePath);
}
}while(_findnext(hFile,&fData) == 0);
_findclose(hFile);//close
return true;
}
