在调用第二个 Action 的地方，手动触发 OnActionExecuting 方法。具体代码如下：

public ActionResult FirstAction()
{
    // do something
    
    // call SecondAction, which doesn't trigger OnActionExecuting
    SecondAction();

    // do something else
}

public ActionResult SecondAction()
{
    // do something

    // manually trigger OnActionExecuting
    var filterContext = new ActionExecutingContext(ControllerContext, new Dictionary());
    foreach (var filter in FilterProviders.Providers.GetFilters(ControllerContext, ActionDescriptor))
    {
        filter.Instance.OnActionExecuting(filterContext);
        if (filterContext.Result != null)
        {
            // if the filter returns a result, stop
            return filterContext.Result;
        }
    }

    // do something else
}
