Definição
Adiciona uma matriz de objetos CacheDependency ao objeto AggregateCacheDependency.Adds an array of CacheDependency objects to the AggregateCacheDependency object.
public:
void Add(... cli::array <System::Web::Caching::CacheDependency ^> ^ dependencies);
public void Add (params System.Web.Caching.CacheDependency[] dependencies);
member this.Add : System.Web.Caching.CacheDependency[] -> unit
Public Sub Add (ParamArray dependencies As CacheDependency())
Parâmetros
- dependencies
- CacheDependency[]
A matriz de objetos CacheDependency a ser adicionada.The array of CacheDependency objects to add.
Exceções
dependencies é null.dependencies is null.
- ou --or-
Um objeto CacheDependency em dependencies é null.A CacheDependency object in dependencies is null.
Um objeto CacheDependency é referenciado em mais de uma entrada Cache.A CacheDependency object is referenced from more than one Cache entry.
Exemplos
O exemplo de código a seguir usa o Add método em conjunto com o AggregateCacheDependency construtor para criar dois CacheDependency objetos, adicioná-los a uma CacheDependency matriz chamada myDepArray e, em seguida, tornar o item no cache dependente desses dois CacheDependency objetos.The following code example uses the Add method in conjunction with the AggregateCacheDependency constructor to create two CacheDependency objects, add them to a CacheDependency array named myDepArray, and then make the item in the cache dependent on those two CacheDependency objects.
' 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)
