Contoh

Contoh kode berikut menggunakan Add metode bersama dengan AggregateCacheDependency konstruktor untuk membuat dua CacheDependency objek, menambahkannya ke CacheDependency array bernama myDepArray, lalu membuat item dalam cache bergantung pada dua CacheDependency objek tersebut.

         ' Create two CacheDependency objects, one to a
         ' text file and the other to an XML file. 
         ' Create a CacheDependency array with these 
         ' two objects as items in the array.
          txtDep = New CacheDependency(Server.MapPath("Storage.txt"))
          xmlDep = New CacheDependency(Server.MapPath("authors.xml"))
          Dim DepArray() As CacheDependency = {txtDep, xmlDep}

          ' Create an AggregateCacheDependency object and 
          ' use the Add method to add the array to it.   
          aggDep = New AggregateCacheDependency()
          aggDep.Add(DepArray)

          ' Call the GetUniqueId method to generate
          ' an ID for each dependency in the array.
          msg1.Text = aggDep.GetUniqueId()
          
          ' Add the new data set to the cache with 
          ' dependencies on both files in the array.
          Cache.Insert("XMLDataSet", Source, aggDep)
