c# - Can't Delete zip files after extracting them -


i have method extracts multiple zip files can't delete them until application close. think it's bug in dotnetzip version 1.9.1.5 library.

my zip files:

hezareh.z01 hezareh.z02 hezareh.z03 hezareh.zip

code extract files:

        private void installupdates()         {             string tempdir = path.combine(environment.currentdirectory, mainviewmodel.temporarydirectoryname);             string mainzipfilename = path.combine(tempdir,                  _updateconfig.zipfiles.single(f => f.isfirstpart).pathonclient); // i'm sure hezareh.zip file             string installpath = path.combine(environment.currentdirectory, properties.settings.default.installationdirectory);             // tried: using (var zipfile = new zipfile(mainzipfilename))              using (var zipfile = zipfile.read(mainzipfilename))             {                 // same problem extractall method.                 // zipfile.extractall(installpath, extractexistingfileaction.overwritesilently);                 foreach (zipentry entiry in zipfile)                 {                     entiry.extract(installpath, extractexistingfileaction.overwritesilently);                 }                 // zipfile.close() or same method not exists , zipfile.dispose() called                 // automatically when call manually still have same problem.             }              deletefiles();         }         private void deletefiles()         {             var files = directory.getfiles(path.combine(environment.currentdirectory, mainviewmodel.temporarydirectoryname));             foreach (string file in files)             {                 file.delete(file); // exception occure here              }         }

this question did not work me , i'm going burn head.
