How to determine if a File Matches a File Mask?

Question

I need to decide whether file name fits to file mask. The file mask could contain * or ? characters. Is there any simple solution for this?

bool bFits = Fits

How about using reflection to get access to the function in the .NET framework?

Like this:

public class PatternMatcher
{
  public delegate bool StrictMatchPatternDelegate(string expression, string name);
  public StrictMatchPatternDelegate StrictMatchPattern;
  public PatternMatcher()
  {
    Type patternMatcherType = typeof(FileSystemWatcher).Assembly.GetType("System.IO.PatternMatcher");
    MethodInfo patternMatchMethod = patternMatcherType.GetMethod("StrictMatchPattern", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public);
    StrictMatchPattern = (expression, name) => (bool)patternMatchMethod.Invoke(null, new object[] { expression, name });
  }
}

void Main()
{
  PatternMatcher patternMatcher = new PatternMatcher();
  Console.WriteLine(patternMatcher.StrictMatchPattern("*.txt", "test.txt")); //displays true
  Console.WriteLine(patternMatcher.StrictMatchPattern("*.doc", "test.txt")); //displays false
}
