Examples

The following example is a console application that queries the change log for all changes to content types in a site collection.

Imports Microsoft.SharePoint

Module ConsoleApp

      Using siteCollection As SPSite = New SPSite("https://localhost")
         Using webSite As SPWeb = siteCollection.RootWeb

            ' Construct a query.
            Dim query As New SPChangeQuery(False, True)

            ' Set a limit on the number of changes returned on a single trip.
            query.FetchLimit = 500

            ' object type
            query.ContentType = True

            Dim total As Long = 0
            While True
               Dim changes As SPChangeCollection = siteCollection.GetChanges(query)

               total += changes.Count

               For Each change As SPChangeContentType In changes

                  ' Get the content type (if it still exists).
                  Dim contentType As SPContentType = _
                      webSite.AvailableContentTypes(change.Id)

                  ' The change might have been to delete the content type.
                  Dim contentTypeName As String
                  If contentType Is Nothing Then

                  Console.WriteLine(vbCrLf + "{0} content type was changed on {1}.", _
                                    contentTypeName, change.Time.ToShortDateString())
                  Console.WriteLine("Type of change: {0}", change.ChangeType.ToString())

               Next change

               ' Break out of the loop when we fetch the last batch of changes.
               If changes.Count < query.FetchLimit Then
                  Exit While
               End If

               ' Go get another batch of changes starting where we left off.
               query.ChangeTokenStart = changes.LastChangeToken

            End While

            Console.WriteLine(vbCrLf + "Total changes = {0:#,#}", total)
