when to create collection class c# code example

Example: c# collection of generic classes

public abstract class MyClass
{
    public abstract Type Type { get; }
}

public class MyClass<T> : MyClass
{
    public override Type Type
    {
        get { return typeof(T); }
    }

    public T Value { get; set; }
}

// VERY basic illustration of how you might construct a collection
// of MyClass<T> objects.
public class MyClassCollection
{
    private Dictionary<Type, MyClass> _dictionary;

    public MyClassCollection()
    {
        _dictionary = new Dictionary<Type, MyClass>();
    }

    public void Put<T>(MyClass<T> item)
    {
        _dictionary[typeof(T)] = item;
    }

    public MyClass<T> Get<T>()
    {
        return _dictionary[typeof(T)] as MyClass<T>;
    }
}
