inheritance question 2

[tekkerguy]

I'm probably a beginner to intermediate c# programmer.

I have a question about inheritance.

I know that

newclass : baseclass is simple inheritance, but if the person types:


newclass : baseclass<someotherclass>


what is that someotherclass, or rather what are they doing there?

 

[Rhys666]

baseclass is most likely a Generic Collection made up of objects of the someotherclass type

And are those inherited as well? what does putting that someotherclass in between <> do?

 

[jmeckley]

generic objects are stongly typed. the simplist example is IList<T>. it has methods like
.Add(T item)
.Remove(T item)
.Contains(T item)

if you define IList<int> = new List<int>();
then the functions read:
.Add(int item)
.Remove(int item)
.Contains(int item)

if you define IList<someotherclass> = new List<someotherclass>();
then the functions read:
.Add(someotherclass item)
.Remove(someotherclass item)
.Contains(someotherclass item)

the same is true for your basecalss<> object.

newclass : baseclass<someotherclass> is a combination between simple inheritance and compile-time inheritance.

Compile-time inheritance is when you have a class Container<T> and you're declaring an object like Container<int> anIntContainer = new Container<int>(...); That is referred to as "compile-time inheritance" if I am not mistaking.
