Remarks

This Feature is Not Available in Express The AggregateCacheDependency class monitors a collection of dependency objects so that when any of them changes, the cached item is automatically removed. The objects in the array can be CacheDependency objects, DBCacheDependency objects or any combination of these.

The AggregateCacheDependency class differs from the CacheDependency class in that it allows you to associate multiple dependencies of different types with a single cached item. For example, if you create a page that imports data from a SQL Server database table and an XML file, you can create a SqlCacheDependency object to represent a dependency on the database table and a CacheDependency to represent the dependency on the XML file. Rather than making an Cache.Insert method call for each dependency, you can create an instance of the AggregateCacheDependency class with each dependency added to it. You can then use a single Insert call to make the page dependent on the AggregateCacheDependency instance.
