Question

My Code looks like that:

public class Artikel : List<Datenschicht.tb_Artikel>
{
     ....
     public void DoSomething()
     {
     ..
     }
}

Now i want to do sth like that:

Artikel[0].DoSomething();

How can i get this number (0) in the method “DoSomething”?

Thank you for your Help!

It sounds like you want the instance of tb_Artikel to know what index it occupies in the List<> structure. If so this is not possible. Objects don’t have any knowledge of their containers. Primarily because objects can be contained in multiple List<> at any given time. Which number would it choose then?

One option though is to simply have the DoSomething take the int value directly. Then let it choose the value from itself to operate on

void DoSomething(int index) {
  this[index].DoSomethingElse();
}
