一个ASP.NET应用程序的Global.Asax文件的Application事件定义如下: protected void Application_Start(Object sender, EventArgs e) { Application["count"]=0; Response.Write(Application["count"].ToString()); } protected void Application_BeginRequest(Object sender, EventArgs e) { Response.Write(Application["count"].ToString()); } protected void Application_EndRequest(Object sender, EventArgs e) { Application["count"]=(Int32)Application["count"]+1; Response.Write(Application["count"].ToString()); } protected void Session_End(Object sender, EventArgs e) { Application["count"]=(Int32)Application["count"]+1; Response.Write(Application["count"].ToString()); } 则程序运行时,以下说法正确的是()。(选一项)
