How to get only filenames within a directory using c#?

When I use the line of code as below , I get an string array containing the entire path of the individual files .

private string[] pdfFiles = Directory.GetFiles("C:\\Documents", "*.pdf");

I would like to know if there is a way to only retrieve the file names in the strings rather than the entire paths.

You can use Path.GetFileName to get the filename from the full path

private string[] pdfFiles = Directory.GetFiles("C:\\Documents", "*.pdf")

EDIT: the solution above uses LINQ, so it requires .NET 3.5 at least. Here's a solution that works on earlier versions:

private string[] pdfFiles = GetFileNames("C:\\Documents", *.pdf");

private static string[] GetFileNames(string path, string filter)
    string[] files = Directory.GetFiles(path, filter);
    for(int i = 0; i < files.Length; i++)
        files[i] = Path.GetFileName(files[i]);
    return files;
