Iterator blocks and inheritance

Question

Given a base class with the following interface:

public class Base
{
    public virtual IEnumerable GetListOfStuff()
    {
        yield return \"F         


        

Answer 1

It's because the iterator gets turned into a private class, and accessing superclass methods from an inner class is not verifiable (as it has to force the 'this' pointer to something other than itself).

Try creating a new private method in Derived:

private IEnumerable GetBaseListOfStuff()
{        
    return base.GetListOfStuff();
}

and call that instead of base.GetListOfStuff()
