Inheritence with Generics
I answered a post on the ASP.NET forums where somebody was having problems with Generics and class inheritence. I ended up cooking this up as an example based upon what they had already provided in the thread.
using System;
using System.Collections.Generic;
public abstract class BaseClass { }
public class ClassA : BaseClass { }
public class ClassB : ClassA { }
public class GenericClass<SomeType> : ClassB { }
public class NonInheritingClass<T> where T : BaseClass
{
private List<GenericClass<T>> m_list;
public virtual int AddToList(GenericClass<T> baseObject)
{
if (this.m_list == null)
{
this.m_list = new List<GenericClass<T>>();
}
this.m_list.Add(baseObject);
return m_list.Count;
}
}
public class SomeClass
{
public static int TestMethod()
{
int count;
NonInheritingClass<ClassB> nonInheritingClass = new NonInheritingClass<ClassB>();
GenericClass<ClassB> classB = new GenericClass<ClassB>();
count = nonInheritingClass.AddToList(classB);
return count;
}
}
