Cast to generic type in C#

Question

I have a Dictionary to map a certain type to a certain generic object for that type. For example:

typeof(LoginMessage) maps to MessageProcessor

        

Answer 1

    public delegate void MessageProcessor(T msg) where T : IExternalizable;


    virtual public void OnRecivedMessage(IExternalizable msg)
    {
        Type type = msg.GetType();
        ArrayList list = processors.Get(type);
        if (list != null)
        {
            object[] args = new object[]{msg};
            for (int i = list.Count - 1; i >= 0; --i)
            {
                Delegate e = (Delegate)list[i];
                e.Method.Invoke(e.Target, args);
            }
        }
    }
