How to get the type of T from a member of a generic class or method?

Question

Let say I have a generic member in a class or method, so:

public class Foo
{
    public List Bar { get; set; }

    public void Baz()
    {         


        

Answer 1

The GetGenericArgument() method has to be set on the Base Type of your instance (whose class is a generic class myClass). Otherwise, it returns a type[0]

Example:

Myclass instance = new Myclass();
Type[] listTypes = typeof(instance).BaseType.GetGenericArguments();
