Sorting an ICollection

Have you ever wanted to sort an ICollection? It took me awhile to figure this one out so I thought I should blog it.

I originally posted this quite awhile ago. Since then I have discovered a much easier way to sort a collection.
Here's an update on sorting collections using LINQ. Much simpler:

 
            var orderedList = customer.Users
            .OrderBy(x => x.UserType)
            .ToList();

And here is my original post on the subject. You decide which one looks easier.

 
private IList<EventReqFormSection> GetSections()
{
 ICollection<EventReqFormSection> sections = EventReqFormSection.GetByEventReqFormId(_businessObject.Id, ObjectManager);
 
 // sort by Display Sequence
 List<EventReqFormSection> sortedValues = new List<EventReqFormSection>(sections);
 sortedValues.Sort(new EventReqFormSection.DisplaySequenceSort());
 
 return sortedValues;
}

The above function retrieves an ICollection puts it into a List object and calls the sort method using an IComparer Object which is a child object of . defined as follows:

 
public class DisplaySequenceSort : IComparer<EventReqFormSection>
{
 public int Compare(EventReqFormSection x, EventReqFormSection y)
 {
  if (x == null)
   throw new ArgumentNullException("x");
  if (y == null)
   throw new ArgumentNullException("y");

  return x.DisplaySequence.CompareTo(y.DisplaySequence);
 }
}
