Question

This is the code:

void Main()
{
    Base.Title.Dump("Base");             // displays "Base Title"
    Child.Title.Dump("Child");           // displays "Base Title"

    Base baseClass = new Base();
    Base childClass = new Child();       // "InvalidOperationException" would be thrown
}

class Base {
    public const string Title = "Base Title";

    public string ClassTitle { get; set; }

    public Base() {
        Type type = this.GetType();

        type.GetFields()
            .First(item => item.Name == "Title")
            .GetValue(this).Dump();
    }
}

class Child : Base {
    private new const string Title = "Child Title";
}

An “InvalidOperationException” exception is thrown in Base constructor.

Answer 1

If you want the derived class Title, you need to either make the child class’ Title public
or rudely crack open its private members with something like this:

Console.WriteLine((type.GetFields(
    System.Reflection.BindingFlags.NonPublic | 
    System.Reflection.BindingFlags.Static)
    .First(item => item.Name == "Title"))
    .GetValue(this));

If you want the base class Title, then your line:

Type type = this.GetType();

is getting the derived type when you want the base type.

Try this instead:

Type type = typeof(Base);
