I\'m creating a child object from a parent object. So the scenario is that I have an object and a child object which adds a distance property for scenarios where I want to s

There is no easy way to do this, unfortunately. As you said, you would either have to use reflection, or create a "Clone" method that would generate a new child object using a parent object as input, like so:

public class MyObjectSearch : MyObject {

    // Other code

    public static MyObjectSearch CloneFromMyObject(MyObject obj)
    {
        var newObj = new MyObjectSearch();

        // Copy properties here
        obj.Prop1 = newObj.Prop1;

        return newObj;
    }
}

No matter what, you're either going to end up writing reflection code (which is slow), or writing each property out by hand. It all depends on whether or not you want maintainability (reflection) or speed (manual property copy).
