Pass delegate as Anonymous Method in C# To Sort List of Objects Using the Sort Method of a Generic List by Les Smith

How can I sort a List of generic objects?  Use a delegate and the default Sort method of the List Object.  Let's say that I have a Business Object that has as one of its properties a List<T>.  I can sort this List of objects using the Sort method of the List Object if I pass it a delegate, as an anonymous method, telling it how to sort the List.  The one line of code that it takes to do this in C# is shown below.  

pn.StatusHistory.Sort(delegate(UserPhoneNumberHistory h1,     UserPhoneNumberHistory h2)     { return h2.HistoryDateTime.CompareTo(h1.HistoryDateTime); });

In this instance, I want the UserPhoneNumberHistory objects sorted in descending order on the HistoryDateTime field.  If I reversed the parameters to the delegate method, the objects would be sorted in ascending order by date and time.

I currently develop mostly in C#, but used VB.NET for years and still do occasionally.  I am always interested in new ways, especially shortcuts, of accomplishing a task.  I don't think you can do the above in VB.NET, at least with one line of code.  However, I was trying to make a ComClass this week to be called from classic VB5 (don't ask why) and found that VB.NET has a ComClass template that automatically creates a class that is callable as Com, but in C# a little more work is involved because C# does not have this kind of a template.  I guess I keep the "flame war" going in my mind:)  Just kidding, I like both languages, much to the chagrin of my current manager.
