初始化 AggregateCacheDependency 類別的新執行個體。
public:
AggregateCacheDependency();public AggregateCacheDependency ();Public Sub New ()範例
下列程式碼範例會使用不採用引數的建構函式，建立 類別的 AggregateCacheDependency 實例。 系統會建立兩 CacheDependency 個 CacheDependency 物件，然後將 新增至陣列 。 myDepArray 這個建構函式會與 Add 方法搭配使用，讓專案儲存在 Cache 相依于這兩 CacheDependency 個物件。
' 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)
備註
這是 類別的 AggregateCacheDependency 無參數建構函式。
