Asp. Analysis of application global object usages in net-practical skills

The example in this article describes the application global object usage in asp.net. Share to everyone for your reference. Specifically as follows:

Application is the application of global objects, shared by all. Another page can read application information, regardless of which page you are manipulating application.

Since application is shared, lock before operation and unlock after operation.

Set up data on one page:

Application.Lock (); 
Application.set ("Address", "Shanghai"); 
Application.UnLock (); 

To fetch data on another page:

string s = (string) application.get ("Address"); 
Button1.Text = s; 

Add a "Global Application Class" Global.asax, Application_Start execution when the first page of the application is accessed.

Take the example of a lot of books, "Statistics visitors", each time the server's previous content is accessed, Application_BeginRequest will execute the number + +. What's wrong with that? Large concurrent access will be very card!

Here to note: Do not use the Web site development as far as possible with application, there is little need to use it when.

I hope this article will help you with the ASP.net program design.
