Get generic instance generic type using reflection

Question

Given:

Type T = typeof(List<string>);

Requirement:

typeof(List<>) == SomeFunction(T)

Many times when I'm reflecting over a type and want to find all properties that return lists of some type...I need the "SomeFunction" shown above. I've searched and searched, but cannot figure out how to get List<> from List<string>. I can use T.GetGenericArguments(), but that only returns string so that doesn't help at all.

typeof(List<string>).GetGenericTypeDefinition() == typeof(List<>)

You know, I tried that before, and I saw List`1 and thought that GetGenericTypeDefinition() was returning List. My bad, your solution works great! – Timothy Baldridge Jun 15 '11 at 14:34
`List\`1` is the same as `List<>`. Likewise, `Func\`2` is `Func`. – leppie Jun 15 '11 at 14:36
