Sorting SharePoint Folder Contents

Posted: November 2, 2010 in SharePoint

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);
  5. foreach (SPFile attachFile in fileList)
  6. {
  7.     // Use the sorted list.
  8. }
