Hi I am already using below code to find files within a folder in asp.net C#. It might be helpful to you too. public string GetOpenOrders(string FileName) { string DirectoryPath = HttpContext.Current.Server.MapPath(~/LocalData); FileInfo[] Files = new DirectoryInfo(DirectoryPath).GetFiles(); List LstFiles = new List (); if (Files.Length == 0) return -1; foreach (FileInfo S in Files) { if (S.Name.ToLower().StartsWith(FileName.ToLower())) LstFiles.Add(S.Name.ToUpper().Remove(S.Name.Length - 4 4)); } return LstFiles; } Hope it helps. Thanks.
