C # Statistics website total number of visitors and current online application

First, open vitualstudio2010, create a new Web site, then add new items, create a new login.aspx and Index.aspx page. Add a new item, select the Global application class, and the page is global.asax.

First step: Open the Global.asax page and write the following code under the Application_Start () method:

Application.Lock ();

application["Count"]=0; Application.set ("Count", 0)/application.add ("Count", 0) initializes the variable, which is equivalent to setting count to 0.

application["Online"]=0;

Application.UnLock ();

Step Two: Write the following code in the Session_Start () method:

Application.Lock ();

Session.Timeout (1); Setting a session to a time of one minute, or no action within a minute, will invalidate the session.

application["Count"]= (int) application["Count"]+1;

application["Online"]= (int) application["online"]+1;

Application.UnLock ();

Step three: Write the following code in the Session_End () method:

Application.Lock ();

Session.Abandon (); When you end a session, log off the session

application["Online"]= (int) application["online"]-1;

Application.UnLock ();

Fourth step: Write the following code in Index.aspx.cs's Page_Load () method:

Response.Write ("<br/> Total number of visitors:" +application["Count"]. ToString ());

Response.wrirte ("<br/> is currently online": "+application["). ToString ());

The total number of visitors to the output and the number of people currently online can also be output through a Label control or other control, such as:

label1.text=application["Count"]. ToString () + "person"

label2.text=application["Online"]. ToString () + "person"
