Answer 1

public class MyClass
{
    public bool MyPredicate(MyClass myClass)
    {
        return true;
    }

    public static bool MyStaticPredicate(MyClass myClass)
    {
        return true;
    }
}

Func<MyClass, bool> predicate = new MyClass().MyPredicate;
Func<MyClass, bool> staticPredicate = MyClass.MyStaticPredicate;
