What is the difference between Type.IsPublic and Type.IsVisible

Question

In C# the Type class instances have a lot of properties. Two of them are IsPublic and IsVisible:

• Type.IsPublic - Gets a value indicating whether the Type is declared public.
• Type.IsVisible - Gets a value indicating whether the Type can be accessed by code outside the assembly.

As far as I know all public members can be accessed outside of the assembly and all others cannot. Two exceptions I can think of are the [InternalsVisibleTo:] assembly attribute and protected modifier for members.

But anyway what is the difference between these two properties?

Answer 1

The links you posted explain this:

IsPublic returns

true if the Type is declared public and is not a nested type; otherwise, false.

IsVisible returns

true if the current Type is a public type or a public nested type such that all the enclosing types are public; otherwise, false.
