This is harder to find in the docs than I imagined. Anyway, I have some instances of Type. How can I find out if they represent classes, methods, interfaces, etc?
class Bla { ... }
typeof(Bla).GetKindOrWhatever() // need to get something like "Class"
(I'm using Mono on Linux but that shouldn't affect the question, I'm making portable code)
Type.IsClass might help here. Also Type.IsInterface.

There are quite a few "IsXxxx" properties on Type. Hopefully these will do what you want.
By the way, you should check out other questions on this subject on SO, including this one...

... if the types you're going to be checking are enum types, as there are some strange (but predictable) results.
There are a slew of properties off the Type class.
typeof(Bla).IsClass
typeof(Bla).IsInterface
etc.

The Type class have some properties that are named IsXXX.
For example it has a IsEnum, IsClass, IsInterface.
If I understand correctly your question this is what you need
As others have mentioned, the Type class has various properties that you can use if you just need to know whether your type is a class, interface, delegate, etc.
If you have a Type object and you want to know if it is a specific type, then I recommend using the IsAssignableFrom method found on the Type class:
Type objectType = obj.GetType();
Type interfaceType = typeof(IExample);
if (interfaceType.IsAssignableFrom(objectType))
{
//...
}
