使用PreApplicationStartMethodAttribute添加Application_Start事件

先预备一个类，用于Start时调用
public static class MyPreApplicationStart
   {
       public static void RegisterGlobalFilters(GlobalFilterCollection filters)
       {
           if (filters != null)
               filters.Add(new HandleErrorAttribute());
       }
 
       public static void Start()
       {
           RegisterGlobalFilters(GlobalFilters.Filters);
       }
   }
这之后通过PreApplicationStartMethodAttribute注册到assembly即可，需要注意的是自定义类必须public ,其中用记Start的方法必须public static
[assembly: PreApplicationStartMethod(typeof(MyPreApplicationStart), "Start")]
