Search all in memory objects .NET

Is there a tool built in开发者_开发技巧to Visual Studio or a third-party add-on that would allow you to search all of the objects in memory for a certain string?

Here is a simple example to give an idea of what I'm trying to accomplish:

Dim myClass as New Foo()
myClass.someVar = "Test"

I would like to be able to search all in-memory objects for the string 'Test' and see which objects have this value. I don't want to manually look through Quick Watch but have a tool that would do that kind of manual searching.
