Is it possible to check if any file with .pdf extension exists on server? I know i can use: File.Exists(Server.MapPath("/somepath"))); but this is when I'm looking for specific file. Is it possible to just look for the file extension?
Yes you can find all the files with certain extension, here is a sample code:
string[] files = System.IO.Directory.GetFiles(Server.MapPath("/somepath"), "*.txt");
Hope this helps.
