I've got this class:

class Foo { 
    public string Name { get; set; }
}

And this class

class Foo<T> : Foo {
    public T Data { get; set; }
}

Here's what I want to do:

public Foo<T> GetSome() {
    Foo foo = GetFoo();

    Foo<T> foot = (Foo<T>)foo;
    foot.Data = GetData<T>();
    return foot;
}

What's the easiest way to convert Foo to Foo<T>? I can't cast directly InvalidCastException) and I don't want to copy each property manually (in my actual use case, there's more than one property) if I don't have to. Is a user-defined type conversion the way to go?
