写站点计数器遇到的application对象赋值的问题?

Question

用c#写asp.net的站点计数器程序: Application["currentGuest"]+=1;或Application["currentGuest"]=count; count是整型,会出错;赋值类型不符.请指教错在哪里?

Answer 1

Application["currentGuest"]对象为object ,必须通过转换最好这么写 
加一个属性
public class XXXX:page
{
   public int count{
      get{
           if( Application["currentGuest"]　＝＝　null )
                 return 0; 
          return (int)Application["currentGuest"];
       } 
       set{ Application["currentGuest"] = value; }   }
   //在函数中这么使
   public void aaa()
   {
      count++;
    }
}
