vb.net - Cannot remove the ReadOnly property from folder -

-

i'm trying remove read-only property of directory can't it.

  private _attributes fileattributes = fileattributes.normal    private sub removereadonlydirectoryattributes(byval path string)         'check root folder         dim di new directoryinfo(path)         di.attributes = _attributes          'check sub folders         each folder string in directory.getdirectories(path, "*", searchoption.alldirectories)             di = new directoryinfo(folder)             di.attributes = _attributes         next      end sub

i have thought code updates attributes normal.

however, when right click on directory see

enter image description here

i have seen posts here on apply method similar 

    dim di new directoryinfo(path)     di.attributes =  di.attributes , not fileattributes.readonly

but doesn't either.

i admin of machine.
