Is there a way to check if a class is inherited?

[Urganot]

Hi,

I am working an a asp.net web api. for this I am generating the controller from a openapi specification. The generator generates the controller classes and methods as abstract.

What I now want to do is to check if all generated controller classes are inherited somewhere.

Finding all controller is easy by using Classes().That().ResideInNamespace("MyProject.Generated.*", true).And().AreAbstract().And() .HaveFullNameContaining("Controller"). What I am struggling with is

1. Finding all methods that are declared in those classes (As far as I can tell, MethodMembers().That().AreDeclaredIn() only accepts Types but Types cant be abstract (Is there to get types from classes?))
2. Finding all classes that inherit those abstract classes

The second point is more important because if all abstract classes are inherited, I can be sure that all abstract methods are overridden.

I'm interested too. I have a rule for sealed class and i want to bypass all the class witch are inherited

Hi @Urganot,

i would assume that the following code would work:

var generatedClasses = Classes().That().ResideInNamespace("MyProject.Generated.*", true).And().AreAbstract().And() .HaveFullNameContaining("Controller");
foreach (var generatedClass in generatedClasses.GetObjects(architecture))
{
    Classes().That().AreAssignableTo(generatedClass).Should().Exist().Check(architecture)
}

AreAssignableTo basically filters by types that are inherited and are thus assignable to the given type. So for each generated class, we can check that there is at least one class that is assignable to the generated class and therefore inherits the generated class.
