Directory.GetFiles: Show only files starting with a numeric value

Question

How can i get the Directory.GetFiles to only show me files starting with a numeric value (eg. 1abc.pdf);

Directory.GetFiles(@\"C:/mydir\", \"0-9*.pdf\")
         


        

Answer 1

There is no way to specify this directly in the search pattern. It's capabilities are pretty limited (mainly supports the * wildcard). The best way to accomplish this is to filter on *.pdf and then use a LINQ query to filter to the ones that start with a digit

Directory
  .GetFiles(@"c:\mydir", "*.pdf")
  .Where(x => Char.IsDigit(Path.GetFileName(x)[0]));
