Casting and templates...

Hi there

The following code doesn't complie:
________________________________________________________
public interface ITree
{
ITree GetFather ();
List GetChildren();
}

public class A : ITree
{
protected A m_father;
protected List m_ListChildren;

public ITree GetFather() { return m_father; }
public List GetChildren() { return m_ListChildren; }
}
________________________________________________________

since "Error 2 Cannot implicitly convert type
'System.Collections.Generic.List' to
'System.Collections.Generic.List'

However A inherits from ITree, so the cast should be working no...
Is there any workaround ?

Hi Oriane,

Classes use polymorphism till they are not generic types :)
So, you can use something like this "new List(m_ListChildren.ToArray());"
to convert the values.

Good point :-(
