Question

Consider I have 2 classes:

public class ComplicatedParent
{
    // Lots of data
}

public class SimpleChild : ComplicatedParent
{
    public string SomeAdditionalData { get; set; }

    public SimpleChild(string arg) : base()
    {
        SomeAdditionalData = arg;
    }
}

And SomeFunction that returns instance of ComplicatedParent. Is there a simple way to construct child from parent’s reference, preserving parent’s state?

Actually ComplicatedParent class and SomeFunction are third party so I can’t change them.

You can’t do this automatically in the language. You can do it with Automaper or by manual assignments.
