HttpResponse.AddFileDependency Method

Adds a single file name to the collection of file names on which the current response is dependent.

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

member AddFileDependency : 
        filename:string -> unit

Parameters

filename
Type: System.String

The name of the file to add.

When you use the AddFileDependency method to add a file dependency, you must also specify output caching programmatically or declaratively. For example, to specify output caching declaratively, use the @ OutputCache directive. For more information, see How to: Cache Page Output with File Dependencies.

The following example shows how to add a single file name to the AddFileDependency file dependency list. If the file changes, the cached response is invalidated.
