I used this code but I am getting the below error """The name 'Directories'/'Server' does not exist in the current context (CS0103) private DataTable GetFilesAndFolders( string virtualDirPath) { DataTable filesAndFolders = new DataTable(); filesAndFolders.Columns.Add( "Name" ); filesAndFolders.Columns.Add( "Path" ); filesAndFolders.Columns.Add( "Type" ); string rootPath = Server.MapPath(virtualDirPath); if (Directory.Exists(rootPath)) { string [] directories = Directory.GetDirectories(rootPath); for ( int i = 0; i { DirectoryInfo drinfo = new DirectoryInfo(directories[i]); DataRow dr = filesAndFolders.NewRow(); dr[ "Name" ] = drinfo.Name; dr[ "Path" ] = drinfo.FullName; dr[ "Type" ] = "D" ; filesAndFolders.Rows.Add(dr); } string [] files = Directory.GetFiles(rootPath); for ( int i = 0; i { FileInfo fInfo = new FileInfo(files[i]); DataRow dr = filesAndFolders.NewRow(); dr[ "Name" ] = fInfo.Name; dr[ "Path" ] = fInfo.FullName; dr[ "Type" ] = "F" ; filesAndFolders.Rows.Add(dr); } return filesAndFolders; } return null ;

Hi, Please use this method to get directory hirarchy private List DirSearch( string sDir) { List files = new List (); try { foreach ( string f in Directory.GetFiles(sDir)) { files.Add(f); } foreach ( string d in Directory.GetDirectories(sDir)) { files.AddRange(DirSearch(d)); } } catch (System.Exception excpt) { MessageBox.Show(excpt.Message); } return files; } Convert into datatable and bind it to gridview
