HttpResponse.AddFileDependency Method

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.

String FileName;
 FileName = "C:\\Files\\F1.txt";
 Response.AddFileDependency(FileName);
