AggregateCacheDependency 建構函式

public:
 AggregateCacheDependency();

public AggregateCacheDependency();

Public Sub New ()

範例

以下程式碼範例使用不接受參數的建構子建立該 AggregateCacheDependency 類別的實例。 先建立兩個 CacheDependency 物件，然後加入一個 CacheDependency 陣列 myDepArray。 此建構子與使儲存在 中的Add項目依賴於兩個Cache物件的方法結合CacheDependency使用。

         ' 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

這是該類別的 AggregateCacheDependency 無參數建構子。
