Get an Object from a Cache (Windows Server AppFabric Caching)

The following examples show the ways you can retrieve objects from the cache.

For more details about the methods that are used in these examples, see these class library topics:

noteNote
These procedures assume that you have already set up your cache cluster and have prepared your development environment. For more information, see Preparing the Cache Client Development Environment (Windows Server AppFabric Caching).

To get an object from the cache

  • Make sure that the using statement (Imports in Visual Basic) is at the top of your application code to reference the Microsoft.ApplicationServer.Caching namespace.

  • Create a DataCacheFactory object that is accessible to all parts of the application that need a cache client. If possible, store and reuse the same DataCacheFactory object to conserve memory and optimize performance.

  • Use the DataCacheFactory object to create a DataCache object (also referred to as the cache client).

  • After you have the DataCache object, use the Get method or the Item property to retrieve an object from cache. In the following examples, the DataCache instance is named myCache.

Example

The following examples assume that a string object was previously added to the cache with a key value of "Key0". For more information about adding objects to the cache, see Add an Object to a Cache (Windows Server AppFabric Caching).

The following example uses the Get method to retrieve an object from cache.

//get string from cache using key "Key0"
string myString1 = (string) myCache.Get("Key0");

The following example uses the Item property that has array notation to retrieve an object from cache.

//get string from cache using array notation
string myString2 = (string) myCache["Key0"];

noteNote
There are many other parameters available for the Get method. For more information, see the DataCache class.
