How do I check if a filename matches a wildcard pattern

Question

I\'ve got a wildcard pattern, perhaps \"*.txt\" or \"POS??.dat\".

I also have list of filenames in memory that I need to compare to that pattern.

How would

Answer 1

You can simply do this. You do not need regular expressions.

using Microsoft.VisualBasic.CompilerServices;

if (Operators.LikeString("pos123.txt", "pos?23.*", CompareMethod.Text))
{
  Console.WriteLine("Filename matches pattern");
}

Or, in VB.Net,

If "pos123.txt" Like "pos?23.*" Then
  Console.WriteLine("Filename matches pattern")
End If

In c# you could simulate this with an extension method. It wouldn't be exactly like VB Like, but it would be like...very cool.
