Is it possible to implement template

[witnes]

Hello. I want to have something like this:

CollectionCIass <int> numbers = new CollectionCIass <int> { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };

but I don't know how to implement this collection.

I can do either like this:
internal class CollectionCIass : System.Collecti ons.Generic.ILi st<int>

but then I can't declare variable like CollectionCIass <int> numbers = new CollectionCIass <int> { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
I need to declare it like
CollectionCIass numbers = new CollectionCIass { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
but I want to specify type in parenthesis.

After some investigations I've found answer:

public class CollectionCIass <T> : System.Collecti ons.IEnumerable
{
private List<T> listOfData = new List<T>();
public void Add(T item)
{
listOfData.Add( item);
}

#region IEnumerable Members

public System.Collecti ons.IEnumerator GetEnumerator()
{
foreach (T data in listOfData)
{
yield return data;
}
}

#endregion
}
