glob pattern matching in .NET

Question

Is there a built-in mechanism in .NET to match patterns other than Regular Expressions? I\'d like to match using UNIX style (glob) wildcards (* = any number of any characte

If you want to avoid regular expressions this is a basic glob implementation:

public static class Globber
{
    public static bool Glob(this string value, string pattern)
    {
        int pos = 0;

        while (pattern.Length != pos)
        {
            switch (pattern[pos])
            {
                case '?':
                    break;

                case '*':
                    for (int i = value.Length; i >= pos; i--)
                    {
                        if (Glob(value.Substring(i), pattern.Substring(pos + 1)))
                        {
                            return true;
                        }
                    }
                    return false;

                default:
                    if (value.Length == pos || char.ToUpper(pattern[pos]) != char.ToUpper(value[pos]))
                    {
                        return false;
                    }
                    break;
            }

            pos++;
        }

        return value.Length == pos;
    }
}

Use it like this:

Assert.IsTrue("text.txt".Glob("*.txt"));
