ASP.NET in a Nutshell

Name

Application

Synopsis

HttpApplicationState = Page.Application

Returns an instance of the HttpApplicationState class, which is the equivalent of the ASP intrinsic Application object. An instance of the HttpApplicationState class contains global information that can be shared across multiple sessions and requests within an ASP.NET application. For more information on the HttpApplicationState class and its members, see Chapter 13.

Parameters

HttpApplicationState

A variable of type HttpApplicationState that receives the instance of the HttpApplicationState class.

Example

The following code example uses Page object’s Application property to add a name/value pair to the Application object and display the value in a label control. Since all of the properties of the Page object are exposed directly to any code associated with the page, it is not necessary to explicitly name the Page class (i.e., Page.Application) to access the Application property.

Sub Page_Load(  )
   Application("Name") = "John Doe"
   Message.Text = "The value <em>" & CStr(Application("Name")) & _
      "</em> has been added to the Application collection."
End Sub

Notes

Although you can retrieve a local object reference to the HttpApplicationState instance for the application, the more common use of this property is to access it directly through the Application property, as shown in the example.
