ASP.NET in a Nutshell

Name

Count

Synopsis

Integer = Application.Count

Returns an Integer containing the number of items currently in the Application collection. The Count member is derived from the ICollection interface, which is implemented by the HttpApplicationState class.

Parameters

Integer

An Integer variable that will receive the Count property value.

Example

The example adds two values to the Application collection, displays the count of items in the Application collection, and then uses the Count property as a looping control value to display each item:

Sub Page_Load(  )
   Application.Clear(  )
   Application("foo") = "Hello, "
   Application("bar") = "World!"
   Message.Text = "The Application collection contains " & _
      Application.Count & " items: "
      Dim I as Integer
      For I = 0 To Application.Count - 1
         Message.Text &= Application(I)
      Next
End Sub

Notes

The Count property is new for ASP.NET. In addition to using the Count property for looping through the Application collection, you can use the property to keep track of how many items the Application stores at any given time. For example, you could write this information to a log for later review.
