Cache.Insert Method (String, Object, CacheDependency)

Inserts an object into the Cache that has file or key dependencies.

Namespace:  System.Web.Caching
Assembly:  System.Web (in System.Web.dll)

public void Insert(
	string key,
	Object value,
	CacheDependency dependencies
)

Parameters

key
Type: System.String

The cache key used to identify the item.

value
Type: System.Object

The object to be inserted in the cache.

dependencies
Type: System.Web.Caching.CacheDependency

The file or cache key dependencies for the inserted object. When any dependency changes, the object becomes invalid and is removed from the cache. If there are no dependencies, this parameter contains null.

ExceptionCondition
ArgumentNullException

The key or value parameter is null.

This method will overwrite an existing cache item whose key matches the key parameter. The object added to the cache using this overload of the Insert method is inserted with no file or cache dependencies, a priority of Default, a sliding expiration value of NoSlidingExpiration, and an absolute expiration value of NoAbsoluteExpiration.

The following example demonstrates how to insert an item into an application's cache with a cache dependency on an XML configuration file.

Cache.Insert("DSN", connectionString, new CacheDependency(Server.MapPath("myconfig.xml")));
