Is there a way to get a list of innerclasses in C#?

Question

As per the title. I'd like a list of all the inner classes of a given class, it can be a list of names or a list of types - I am not fussed. Is this possible? I thought there might be a way using reflection but haven't been able to find one.

Answer 1

You want Type.GetNestedTypes. This will give you the list of types, which you can then query for their names.

Answer 2

Doesn't Type.GetNestedTypes do what you want?

Note that if you want to get "double-nested" types, you'll need to recurse - as Foo.Bar.Baz is a nested type in Foo.Bar, not in Foo.

For "modern" environments (.NET 4.5, PCLs, UWA etc) you need TypeInfo.DeclaredNestedTypes instead, e.g. type.GetTypeInfo().DeclaredNestedTypes, using the GetTypeInfo() extension method.

Answer 3

Type.GetNestedTypes() will return the public nested types of the specified Type.

If you also want the private and internal nested types, you must call the Type.GetNestedTypes(BindingFlags bindingFlags) method like this:

Type[] nestedTypes = typeof(MyType).GetNestedTypes(BindingFlags.Static |
                                                   BindingFlags.Instance |
                                                   BindingFlags.Public |
                                                   BindingFlags.NonPublic);

Answer 4

Type[] nested = typeof(SomeClass).GetNestedTypes();

Answer 5

Yes, there is. Use Type.GetNestedTypes().
