这些Filter可以被应用在类或者方法上，下面我们来看一下他们的执行顺序。首先我们写一个BaseController并加上两个Filter：
[MyFilter2(Target = "BaseController")]
[MyFilter1(Target="BaseController")]
public class BaseController : Controller
{
}
[MyFilter1(Target="BaseController")]
public class BaseController : Controller
{
}
应为Controller类是实现这几个Filter接口的，所以我们在HomeController中重写Controller基类中的所有Filter接口的方法，并在HomeController类和里面的Filter方法加上我们自定义的MyFilter：
HomeController
[MyFilter2(Target = "HomeController")]
//[MyFilter1(Target = "HomeController")]//注意我在这里把MyFilter1注释了.
[HandleError]
public class HomeController : BaseController
{
[MyFilter2(Target = "HomeController.Filter")]
[MyFilter1(Target = "HomeController.Filter")]
public ActionResult Filter()
{
return Content("<div>这是在Action方法里面返回的内容！</div>");
}
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnActionExecuted方法添加的内容！</div>");
}
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnActionExecuting方法添加的内容！</div>");
}
protected override void OnAuthorization(AuthorizationContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnAuthorization方法添加的内容！</div>");
}
protected override void OnException(ExceptionContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnException方法添加的内容！</div>");
filterContext.ExceptionHandled = true;
}
protected override void OnResultExecuted(ResultExecutedContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnResultExecuted方法添加的内容！</div>");
}
protected override void OnResultExecuting(ResultExecutingContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnResultExecuting方法添加的内容！</div>");
}
}
[MyFilter2(Target = "HomeController")]
//[MyFilter1(Target = "HomeController")]//注意我在这里把MyFilter1注释了.
[HandleError]
public class HomeController : BaseController
{
[MyFilter2(Target = "HomeController.Filter")]
[MyFilter1(Target = "HomeController.Filter")]
public ActionResult Filter()
{
return Content("<div>这是在Action方法里面返回的内容！</div>");
}
protected override void OnActionExecuted(ActionExecutedContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnActionExecuted方法添加的内容！</div>");
}
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnActionExecuting方法添加的内容！</div>");
}
protected override void OnAuthorization(AuthorizationContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnAuthorization方法添加的内容！</div>");
}
protected override void OnException(ExceptionContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnException方法添加的内容！</div>");
filterContext.ExceptionHandled = true;
}
protected override void OnResultExecuted(ResultExecutedContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnResultExecuted方法添加的内容！</div>");
}
protected override void OnResultExecuting(ResultExecutingContext filterContext)
{
filterContext.HttpContext.Response.Write("<div>这是在HomeController里面重写OnResultExecuting方法添加的内容！</div>");
}
}
