C# - Ways to rename a directory -


this question has answer here:

i'm using directory.move(olddir, newdir) rename directory. every , ioexception saying "access path 'olddir' denied". if right click directory in explorer can rename without issues.

so question is: there other ways rename directory without using directory.move?

i thought of using command shell (process.start()) should last way of doing it.

further details

the program still running, exception , can rename manually in windows explorer (right click -> rename) while cursor paused on breakpoint in catch block. tried setting breakpoint @ directory.move, renamed directory in explorer (and again), stepped on directory.move , ended in catch (ioexception) again.

here code

public bool copy() {     string destpathrelease = thisuser.destpath + "\\release";      if (directory.exists(destpathrelease))     {         try         {             string newpath = thisuser.destpath + '\\' + (string.isnullorempty(currbuildlabel) ? ("release" + '_' + datetime.now.tostring("yyyymmdd_hhmmss")) : currbranchname) + '.' + currbuildlabel;             directory.move(destpathrelease, newpath);         }            catch (ioexception)         {            // breakpoint         }     } }

as can see entered method. never touched directory in program before.

since way not working me need find way so.

solution

public bool copy() {     string destpathrelease = thisuser.destpath + "\\release";      shfileopstruct struc = new shfileopstruct();      struc.hnamemappings = intptr.zero;     struc.hwnd = intptr.zero;     struc.lpszprogresstitle = "rename release directory";     struc.pfrom = destpathrelease + '\0';     struc.pto = thisuser.destpath + '\\' + (string.isnullorempty(this.currbuildlabel) ? ("release" + '_' + datetime.now.tostring("yyyymmdd_hhmmss")) : this.currbranchname) + '.' + this.currbuildlabel + '\0';     struc.wfunc = filefuncflags.fo_rename;      int ret = shfileoperation(ref struc); }

please note it's important use pto , pfrom 0 delimited double 0 terminated strings.

you try using p/invoke call shfileoperation api (or ifileoperation interface). explorer uses in theory, should replicate functionality more directly.
