Regex Advance---待验证

Match matchB = Regex.Match("abcdaBCdefg", @"\Babcd\B", RegexOptions.IgnoreCase);
Console.WriteLine(matchB.Value);
Match matchBError = Regex.Match("abcdaBCdefg", @"\babcd\b", RegexOptions.IgnoreCase);
Console.WriteLine("match error " + matchBError.Value);

Match mathcb = Regex.Match("good bad regexsoso", @"\bbad\b", RegexOptions.IgnoreCase);
Console.WriteLine(mathcb.Value);
Match mathcbError = Regex.Match("good bad regexsoso", @"\Bad\B", RegexOptions.IgnoreCase);
Console.WriteLine("match error" + mathcb.Value);

等验证。。。
