c# sorting a List<> using Tuple?

Question

I need to sort a List<> of MediaItem objects by publish date...the publish date is not a property of the item. So my initial intention was to temporarily tack on a publi

Answer 1

One way would be to use the List.Sort method, using a lambda-expression to create the appropriate Comparison delegate.

// Sorts tuples in chronological order. To use reverse chronological order,
// use t2.Item2.CompareTo(t1.Item2) instead.
list.Sort((t1, t2) => t1.Item2.CompareTo(t2.Item2));

This of course assumes that there are no null-references in the list, which there can't be in your example.
