Question

I have a List<MyClass> and I want to sort it by DateTime CreateDate attribute of MyClass.

Is that possible with LINQ ?

Thanks

You can enumerate it in sorted order:

IEnumerable<MyClass> result = list.OrderBy(element => element.CreateDate);

You can also use ToList() to convert to a new list and reassign to the original variable:

list = list.OrderBy(element => element.CreateDate).ToList();

This isn’t quite the same as sorting the original list because if anyone still has a reference to the old list they won’t see the new ordering. If you actually want to sort the original list then you need to use the List<T>.Sort method.
