Look up IComparable, then implement it in your DocumentReference class. ArrayList can sort any class that implements this interface.

[mailto:[EMAIL PROTECTED] On Behalf Of Hevel, Shawn Sent: Friday, September 15, 2006 11:07 AM To: [email protected] Subject: [ADVANCED-DOTNET] ArrayList Sort Method I have an unusual situation or at least I think I do. I need to sort an ArrayList, but my ArrayList is made up of a class called DocumentReference. Inside this class are different properties that pertain to a Document (ReportId, VersionId, Description etc). What I need to do is sort this based on certain criteria. They only way I know how to do this is by building a temporary table with columns that pertain to each property. I would then move the value of each property into the specified column until all properties are read. Once all ArrayList members are read I can create a DataView from the DataSet and do the following: dvTopicList.Sort = "VersionID DESC" or dvTopicList.Sort = "Description, ReportID" After the list is sorted, I would rebuild my ArrayList and return this back to the calling program. I know that ArrayList has a sort method but I don't think it will work for me. Does anyone have any ideas about approaching this? or a better way of doing it?
