How to capture value OOPS & Generic [closed]

by

While looking at your code, why would one want to read class specific properties in a generic method?

The only solutions i see is to use Reflection, or create an abstract base class with a before save method and call that method in de Save() method. Add a generic type constraint to the DBObject class defining that T is of the basetype. This way you can add class specific functionality to a generic method. Something like this:

public abstract class Base
{
     public virtual void BeforeSave()
     {

     }

}

public class User : Base
{
     public string Name { get; set; }
     public int Age { get; set; }      

     public override void BeforeSave()
     {
          // You can access your properties here
          if (this.Name.Trim() == "")
              throw new Exception("Name is mandatory!")
     }

}

public class DBObject<T>
    where T: Base
{
    public void Save()
    {
        T.BeforeSave();
    }
}
