Sorting SharePoint Folder Contents

Recently I needed to sort the contents of a SharePoint folder, in which I used IComparer to get my task done. Following is the code I used. Hope it is helpful.

As you see below I am using the TimeCreated property of SPFile object to do the comparison, other than this you can use any other property of the SPFile object. For a list of available properties refer MSDN.

1. // Comparer Class.
2. public class SPFilesComparer : IComparer
3. {
4.     #region IComparer Members
5.     public int Compare(object object1, object object2)
6.     {
7.         return new CaseInsensitiveComparer().Compare(((SPFile)object1).TimeCreated, ((SPFile)object2).TimeCreated);
8.     }
9.     #endregion
10. }

1. ArrayList fileList = new ArrayList(attachFiles);
2. IComparer compFiles = new SPFilesComparer();
3. // Do the sorting based on the SPFilesComparer.
4. fileList.Sort(compFiles);
6. foreach (SPFile attachFile in fileList)
7. {
8.     // Use the sorted list.
9. }
