How to reflect a nested delegate in C#?

Given the following (minimal) class:

public class TestEvents
{
    public delegate void MyDelegate(params string[] data);

    public TestEvents()
    {
    }
}

If I retrieve the Type object representing this class from an assembly how can I identify all nested delegates defined in this class? I can find a lot of information how to invoke a delegate via reflection, but nothing on how to obtain a suitable object from a Type object in the beginning (without knowing the delegates name).
