Task: quickly fill in the fields of the decorator class

Question

Suppose we have Modelseveral properties on it, and we want to create a decorator class for this model to improve it with some additional properties. Now we want to create a new instance DecoratedModelfilled with all the property values Model, possibly using the constructor with Modelas a parameter:

public class DecoratedModel : Model
{
    public DecoratedModel(Model baseModel)
    {
        // Populate decorated model generically from baseModel
    }
}
