Readymade delegates in ASP.NET 2.0

Question

What are the readymade delegates like

delegate void Action<T>(T obj);
delegate TOutput Converter<TInput, TOutput>(TInput input);
delegate Boolean Predicate<T>(T obj);
Function delegate

available in ASP.NET 2.0.

Answer 1

Try something like this to print a list, although the list will also contain any special-purpose delegates too:

foreach (Type t in typeof(object).Assembly.GetTypes())
{
    if (t.IsPublic && typeof(Delegate).IsAssignableFrom(t))
        Console.WriteLine(t.Name);
}

Answer 2

All of these are 3.5 c# stuff so the answer is no one (but you can declare them by your own)
