As the title says, how do you use reflection to check if a class definition is defined as internal? "typeof(...)" returns certain properties shown below but not whether a class is defined as internal. Looked on Google but all I could find were lots of articles about running internal or protected methods using reflection. It's not the methods I'm interested in this case, but the class definition.
var type = typeof(Customer); Assert.IsTrue(type.IsClass); Assert.That(type.IsAbstract, Is.EqualTo(isAbstract)); Assert.That(type.IsPublic, Is.EqualTo(isPublic)); Assert.That(type.IsPublic, Is.EqualTo(isPublic)); Assert.That(type.IsSealed, Is.EqualTo(isSealed)); Assert.That(type.IsSerializable, Is.EqualTo(isSerializable));

Reflection in C# is used to retrieve metadata on types at runtime. In other words, you can use reflection to inspect metadata of the types in your program dynamically -- you can retrieve information on the loaded assemblies and the types defined in them.
Reflection provides objects (of type Type) that describe assemblies, modules, and types. You can use reflection to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties.
Using reflection in C# language, we can access the private fields, data and functions etc.
This is a classic issue. From MSDN:
The C# keywords
protectedandinternalhave no meaning in IL and are not used in the Reflection APIs. The corresponding terms in IL areFamilyandAssembly. To identify aninternalmethod using Reflection, use theIsAssemblyproperty. To identify aprotected internalmethod, use theIsFamilyOrAssembly.
Reflection does not expose a way on Type check if it is internal, protected or protected internal.

Does the IsVisible method give you the value you are looking for?
