C# String Like

I had a need to find a string like function similar to MSSQL and found this useful function.

public static bool StringLike(this string toSearch, string toFind)
{
return new Regex(@"A" + new Regex(@".|$|^|{|[|(|||)|*|+|?|").Replace(toFind, ch => @"" + ch).Replace('_', '.').Replace("%", ".*") + @"z", RegexOptions.Singleline).IsMatch(toSearch);
}

bool willBeTrue = StringLike("abcdefg","abcd_fg");
bool willAlsoBeTrue = StringLike("abcdefg","ab%f%");
bool willBeFalse = StringLike("abcdefghi","abcd_fg");
