Can I have a class with a generic list and expose that as the default value
c#, generics
Solution
You could make PersonList implement `IEnumerable<Person>`
public class PersonList : IEnumerable<Person>
{
public List<Person> myIntenalList;
public IEnumerator<Person> GetEnumerator()
{
return this.myInternalList.GetEnumerator();
}
Person CustomFunction()
{...}
}
Or even simpler, just make PersonList extend List:
public class PersonList : List<Person>
{
Person CustomFunction() { ... }
}
The first method has the advantage of not exposing the methods of `List<T>`, while the second is more convenient if you want that functionality. Also, you should make myInternalList private.
Problem
I basically want to do this in code: ``` PersonList myPersonList; //populate myPersonList here, not shown Foreach (Person myPerson in myPersonList) { ... } ``` Class declare ``` public class PersonList { public List<Person> myIntenalList; Person CustomFunction() {...} } ``` So how do I expose "myInternalList" in my class as the default value that the Foreach statement can use it? Or can I? Reason being is that I have about 50 classes that are currently using GenericCollection that I'd like to move to generics but don't want to re-write a ton.
