Example
O exemplo de código a seguir exibe informações sobre os itens em uma lista que foram alterados após uma data especificada. O exemplo usa um objeto XmlDocument para criar objetos XmlNode de parâmetros.
Esse exemplo requer que um using (Visual C#) ou Imports (Visual Basic) diretiva estar incluído para o namespace System.Xml.
Dim listService As New Web_Reference_Folder.Lists()
listService.Credentials = System.Net.CredentialCache.DefaultCredentials
Dim xmlDoc = New System.Xml.XmlDocument()
Dim ndViewFields As XmlNode =
xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "")
Dim ndContains As XmlNode =
xmlDoc.CreateNode(XmlNodeType.Element, "Contains", "")
ndViewFields.InnerXml = "<FieldRef Name='Field1'/>" + _
"<FieldRef Name='Field2'/><FieldRef Name='Field3' />"
ndContains.InnerXml = "<FieldRef Name='Field'/>" + _
"<Value Type='Number'>Number</Value>"
Try
Dim ndListChanges As XmlNode =
listService.GetListItemChanges("List_Name", _
ndViewFields, "2003-06-18T00:00:00Z", ndContains)
MessageBox.Show(ndListChanges.OuterXml)
Catch ex As System.Web.Services.Protocols.SoapException
MessageBox.Show("Message:" + ControlChars.Lf + ex.Message +
