Response. Add File Dependency(String) Method
Adds a single file name to the collection of file names on which the current response is dependent.
public: void AddFileDependency(System::String ^ filename);
public void AddFileDependency (string filename);
member this.AddFileDependency : string -> unit
Public Sub AddFileDependency (filename As String)
The name of the file to add.
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);
Dim FileName As String FileName = "C:\Files\F1.txt" Response.AddFileDependency(FileName)
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.
