You create an event receiver. The ItemAdded method for the event receiver contains the following
code segment. (Line numbers are included for reference only.) 01 SPWeb recWeb =
properties.Web; 02 using (SPSite siteCollection = new SPSite(“http://site1/hr”)) 03 { 04 using
(SPWeb web = siteCollection.OpenWeb()) 05 { 06 PublishingWeb oWeb =
PublishingWeb.GetPublishingWeb(web); 07 PublishingWebCollection pubWebs =
oWeb.GetPublishingWebs(); 08 foreach (PublishingWeb iWeb in pubWebs) 09 { 10 try 11 { 12
SPFile page = web.GetFile(“/Pages/default.aspx”); 13 SPLimitedWebPartManager wpManager =
page.GetLimitedWebPartManager (PersonalizationScope.Shared); 14 } 15 finally 16 { 17 if (iWeb
!= null) 18 { 19 iWeb.Close(); 20 } 21 } 22 } 23 } 24 } You need to prevent the event receiver from
causing memory leaks. Which object should you dispose of?
