The Web Part contains the following code segment. (Line numbers are included for reference only.)

01 protected override void CreateChildControls()
02 {
03 base.CreateChildControls();
04 SPSecurity.RunWithElevatedPrivileges(
05 delegate()
06 {
07 Label ListCount = new Label();
08 ListCount.Text = String.Format(“There are {0} Lists”, SPContext.Current.Web.Lists.Count);
09 Controls.Add(ListCount);
10 });
11 }
