C# linq sort - quick way of instantiating IComparer

Question

When using linq and you have

c.Sort()

Is there any good inline way of defining a Comparison and/or IComparer class w

Answer 1

I've no idea what c.Sort() is in your example, as it can be many things (do you mean List.Sort()?), but one thing that it sure isn't is LINQ. LINQ doesn't have Sort() - it has OrderBy().

That said, the latter also works with IComparer, and there's no way to create an instance of anonymous class implementing the interface "inline", so you'll have to define a class.

For List.Sort(), there is an overload which takes Comparison. Since it's a delegate type, you can use a lambda to provide the function inline:

List xs = ...;
xs.Sort((x, y) => y - x); // reverse sort
