Examples
The following example is a console application that queries the change log for all changes to content types in a site collection.
Imports System
Imports Microsoft.SharePoint
Module ConsoleApp
Sub Main()
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
contentTypeName = "Unknown"
Else
contentTypeName = contentType.Name
End If
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)
End Using
End Using
Console.Write(vbCrLf + "Press ENTER to continue...")
Console.ReadLine()
End Sub
