Question

With method signatures like:

public interface TestInterface
{
    void SampleMethodOut(out int? nullableInt);
    void SampleMethod(int? nullableInt);
}

I’m using typeof(TestInterface).GetMethods()[1].GetParameters()[0].ParameterType to get the type, and then checking IsGenericType and Nullable.GetUnderlyingType. How can I do this with the method with the out parameter?

Doh, ignore my previous answer.

You use Type.IsByRef, and call Type.GetElementType() if so:

var type = method.GetParameters()[0].ParameterType;
if (type.IsByRef)
{
    // Remove the ref/out-ness
    type = type.GetElementType();
}
