Question

I have a generic repository that I use for common things such as FetchAllData, GetbyID and so on… Anyway, I want to include a Deactivate(T Entity) method so that instead of deleting data I will just turn their status off so the user will not see the data, but I can see it whenever I need. Basically, something similar to:

public interface IGenericRepository<T> where T : class {
     ...somecode
}

public class GenericRepository<T> : IGenericRepository<T> where T : class {
    public T GetbyID(int id) { ... }

    public void Deactivate(T entity) {
        entity.stat = 0; // I know that this stat is common in all tables. However,
                         // my problem is that I don't know how to make appear stat
                         // in IntelliSense.
    }
}

I know that this can be done, but I how do I do it?

Answer 1

Declare a interface:

public interface IDeactivatable {
    int stats { get; set; }
}

Then your entities must derive from IDeactivatable.

Tip: You can add a generic type constraint too:

 [...] IGenericRepository<T> where T : class, IDeactivatable [...]
