網站統計在線人數的功能已經很普遍，主要應用了全局變量application和session對象。描述說明就免了，大家都很熟悉簡單貼一下代碼，在Global.asax文件中寫如下代碼

1 protected void Application_Start(object sender, EventArgs e) 2 { 3 HttpApplicationState applicationstate = GetApplicationstate(); 4 applicationstate["Count"] = 0; 5 } 6 7 private static HttpApplicationState GetApplicationstate() 8 { 9 //獲取上下文對象 10 HttpContext context = HttpContext.Current; 11 //獲得application對象 12 HttpApplicationState applicationstate = context.Application; 13 //在網站啟動時默認當前在線人數為0 14 return applicationstate; 15 } 16 17 protected void Session_Start(object sender, EventArgs e) 18 { 19 20 HttpApplicationState applicationstate = GetApplicationstate(); 21 //訪問人數增加一個 22 applicationstate["Count"] = (int)applicationstate["Count"]+1; 23 } 24 protected void Session_End(object sender, EventArgs e) 25 { 26 HttpApplicationState applicationstate = GetApplicationstate(); 27 //訪問人數減少一個 28 applicationstate["Count"] = (int)applicationstate["Count"] - 1; 29 }

???? 然后在頁面獲取一下application["Count"]就可以了。在pageload事件中加上：this.lblCount.Text = this.Application["Count"].ToString();

在前臺加一個label：

當前在線人數：<asp:Label runat="server" ID="lblCount"></asp:Label>

統計在線人數就完成了。
