word-boundary

I am wondering why the following regex does not match.

string query = "\"1 2\" 3";
string pattern = string.Format(@"\b{0}\b", Regex.Escape("\"1 2\""));
string repl = Regex.Replace(query, pattern, "", RegexOptions.CultureInvariant);

Note that if I remove the word boundary characters (\b) from pattern, it matches fine. Is there something about '\b' that might be tripping this up?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
