c# - How to find types that are direct descendants of a base class? -

i need types of assembly inherits base class first descendants. instance if have:

class base {  }  class firstclass : base {  }  class secondclass : firstclass {  }

now

var directones = assembly.gettypes().where(t => t.issubclassof(typeof(base)));

should return firstclass , not secondclass. there way find out?

instead of issubclassof() can use type.basetype

e.g.

var directones = assembly.gettypes().where(t => t.basetype == (typeof(base)));

(fyi: don't think there's way find interfaces type directly implements.)
