C + + recursive deletion of a directory instance _c language

Source: Internet
Author: User

This article illustrates the implementation of recursive deletion of a directory by C + +. Share to everyone for your reference. The specific methods are as follows:

The use framework of Cfindfile is as follows:

Copy Code code as follows:
void Recurse (LPCTSTR pstr)
{
CFileFind Finder;

Build a string with wildcards
CString Strwildcard (PSTR);
Strwildcard + = _t ("\\*.*");

Start working for files
BOOL bworking = Finder. FindFile (Strwildcard);

while (bworking)
{
bworking = Finder. FindNextFile ();

Skip. and.. Files Otherwise, we ' d
Recur infinitely!

if (finder. Isdots ())
Continue

If it ' s directory, recursively search it

if (finder. Isdirectory ())
{
CString str = finder. GetFilePath ();
TRACE (_t ("%s\n"), (LPCTSTR) str);
Recurse (str);
}
}

Finder. Close ();
}

The recursive deletion code is as follows:

Copy Code code as follows:
Loop Delete a directory
void Recursivedelete (CString strdir)
{
CFileFind FF;
CString strpath;
strpath = Strdir;
if (Strpath.right (1)!= ' \ ")
{
strpath + = ' \ ';
}
strpath + = "*.*";

BOOL bworking = ff. FindFile (strpath);
while (bworking)
{
bworking = ff. FindNextFile ();

Skip. and.. Files Otherwise, we ' d
Recur infinitely!
if (ff. Isdots ())
Continue

If it ' s directory, recursively search it

if (ff. Isdirectory ())
{
Recursive directory
CString str = ff. GetFilePath ();
TRACE (_t ("%s\n"), (LPCTSTR) str);
Recursivedelete (str);
Delete Directory
:: Setfileattributesa (str, file_attribute_normal);
:: RemoveDirectory (str);
}
Else
{
deleting files
CString str = ff. GetFilePath ();
TRACE (_t ("%s\n"), (LPCTSTR) str);
:: SetFileAttributes (str, file_attribute_normal);
::D eletefile (str);
}
}

Ff. Close ();

}
int main (int argc, char *argv[])
{
Recursivedelete ("c:\\20_128\\");
return 0;
}

I hope this article will help you with the C + + program design.
