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")
To get files that start with any numeric value, regardless of the number of digits, you could use a regular expression:
var files = Directory.GetFiles(@"c:\mydir", "*.pdf")
.Where(file => Regex.IsMatch(Path.GetFileName(file), "^[0-9]+"));
//.ToArray() <-add if you want a string array instead of IEnumerable
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]));
