C# Copy file or folder -

i trying write program keep multiple folders in sync. this, need copy , delete files , subfolders.

to me, doesn't make difference if object file or folder, want create necessary parent folders , copy object, overwriting if necessary. i'm using jagged array of filesysteminfo hold files/folders.

this has advantage of avoiding duplication of code sync files , folders separately.

however, can't figure out how copy filesysteminfo. i'm looking way able copy/delete/read creation or modified time work on both files , folders.

filesysteminfo don't have copy or delete methods base class directoryinfo , fileinfo.

so when loop on filesysteminfo objects have cast proper concrete class , use specific copy/delete methods.

foreach( var fsi in filesysteminfoobjects ) {      if( fsi directoryinfo )      {         var directory =  (directoryinfo)fsi;         //do      }      else if (fsi fileinfo )      {         var file = (fileinfo)fsi;         //do      } }
