PixelPlex (above) has provided the best answer. All I had to add to PixelPlex's code was an If statement to set the ComboBox to a value when it was found. The foreach is therefore as below in my case ...

            foreach (UITestControl childControl in parentControl.GetChildren())
            {
                children.Add(GetChildControls(childControl));

                //Added below If statement to set ComboBox selected item to "Carrots"...
                if (childControl.ClassName == "Uia.ComboBox")
                {
                    WpfComboBox cb = (WpfComboBox)childControl; 
                    cb.SelectedItem = "Carrots";
                }
            }

This selects Carrots from my ComboBox... Everything that does not satisfy my If statement is not relevant so I don't do anything with it.
