Now do some string replacement on regex like * with w+ etc

尝试以下代码

try below code

public static class WildcardMatch
{
    #region Public Methods
    public static bool IsLike(string pattern, string text, bool caseSensitive=false)
    {
        pattern = pattern.Replace(".", @"\.");
        pattern = pattern.Replace("?", ".");
        pattern = pattern.Replace("*", ".*?");
        pattern = pattern.Replace(@"\", @"\\");
        pattern = pattern.Replace(" ", @"\s");
        return new Regex(pattern, caseSensitive ? RegexOptions.None : RegexOptions.IgnoreCase).IsMatch(text);
    }
    #endregion
}
