On .NET 4:

You can do something kind of like what you want minus the need for regex (and you shouldn't use regex for something like this!) by using the dynamic feature of C# 4.0 described here: http://www.drowningintechnicaldebt.com/ShawnWeisfeld/archive/2010/08/22/using-c-4.0-and-dynamic-to-parse-json.aspx

The only downside is that you can't guarantee what the exact structure of the object is.

The upswing is that instead of accessing members via yourDynamicObject['blah'], it's the more duck-type-ish yourDynamicObject.blah

On .NET 3.5:

You can use Json.NET: http://json.codeplex.com/
