Get properties of properties of a class

I want to get the properties of the properties of a class.

What I have right now:

    foreach (var v in test.GetType().GetProperties())
    {
        foreach (var p in v.GetType().GetProperties())
        {
        }
    }

The first foreach loop works fine and gets the properties of the class variable test. However, in the second loop, I get output such as MemberType, ReflectedType, Module etc.. not actual properties.

My goal is to get the properties of the properties of a class and then edit their value (truncate them using another function).

Thanks.
