Retrieving Data from the Cache

Retrieving objects stored within the cache is simple; there are two options for doing so:

Dictionary style-Using patterns similar to that of Session and Application.

Cache.Get() API-The Get() method accepts a single parameter that fetches the

value of the named key.

Given the example used in Section 4.3 that added a dataset into the cache using the key

MyProducts, you could retrieve this value from the Cache:

' Get a value from the cache

<script runat="server">

Sub Page_Load(object As Sender, e As EventArgs)

Dim ds As DataSet

If (Cache("MyProducts") Is Not Nothing) Then ' Uses Dictionary style API

ds = CType(Cache.Get("MyProducts"), DataSet) ' Uses Get() method

End If

End Sub

</script>

Comments

Getting items stored within the cache is very simple. Although both techniques-dictionary

style and Get()-are used in this example, the dictionary style access is the one

most frequently used.
