Question

I have ViewModel classes like these that follow:

public class ReferenceDetailsViewModel
{
    public ReferenceDetailsViewModel() {
        this.Timer = new List<long>();
    }
    public IEnumerable<Reference.Grid> Grid { get; set; }
    public List<long> Timer { get; set; }
}

public class ContentDetailsViewModel
{
    public ContentDetailsViewModel() {
        this.Timer = new List<long>();
    }
    public IEnumerable<Content.Grid> Detail { get; set; }
    public SelectList Statuses { get; set; }
    public SelectList Types { get; set; }
    public List<long> Timer { get; set; }
}

They all have in common a Timer field and this is initialized in the constructor.

Is there a way that I could create a baseViewModel and have these inherit the Timer field so as to avoid coding the same thing for each ViewModel that has a timer ?

Answer 1

Yes, code an abstract class and make concrete classes inherit from this.

public abstract class BaseDetailsViewModel
{
    protected BaseDetailsViewModel() {
        Timer = new List<long>();
    }
    public List<long> Timer { get; set; }
}
