Ways to traverse folders

To traverse only the subfolders and root folders below the file directory method:

DirectoryInfo Thefolder =NewDirectoryInfo (@"e:\ Work \work");//action classes for filesfileinfo[] Filerootinfo= Thefolder.getfiles ();//returns the file of the current root directory            foreach(FileInfo Nextfileinchfilerootinfo) {                 This. LISTBOX1.ITEMS.ADD (Nextfile.name);//traversing Files} directoryinfo[] Dirinfo= Thefolder.getdirectories ();//returns the current file subdirectory//Traverse Folder            foreach(DirectoryInfo Nextfolderinchdirinfo) {               //This.listBox2.Items.Add (nextfolder.name);fileinfo[] FileInfo = Nextfolder.getfiles ();//returns the file of the current file subdirectory                foreach(FileInfo NextfileinchFileInfo)//traversing Files                     This. LISTBOX2.ITEMS.ADD (Nextfile.fullname); }

Recursively traverse all the folders below the folder's subclass directory:

   PublicArrayList Al =NewArrayList (); //I used the ArrayList as a dynamic array .         Public voidGetalldirlist (stringStrbasedir) {DirectoryInfo di=NewDirectoryInfo (Strbasedir); Directoryinfo[] DiA=di.            GetDirectories ();  for(inti =0; i < dia.length; i++) {al. ADD (Dia[i].                FullName); //Dia[i]. FullName is the absolute address of a subdirectory and records it in ArrayListgetalldirlist (Dia[i].                FullName); //Note: recursion. People with logical thinking should be able to react.            }             for(inti =0; I < al. Count; i++)            {                 This. LISTBOX1.ITEMS.ADD (Al[i]. ToString () +" "); //TextBox1 is a container, copy my Code, pay attention to changing your own container.            }        }
