asp.net-mvc - 自定义视图引擎中的 ASP.NET MVC 自定义属性

Question

假设我写了一个自定义属性......

public class SpecialActionFilterAttribute : System.Web.Mvc.ActionFilterAttribute
{
    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
    }
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // set some parameters here. 
    }
    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
    }
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
    }
}

然后我创建一个自定义 ViewEngine，并覆盖 FindView/FindPartialView...

    public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
    {
        // how can I get those parameters here? 

        return base.FindView(controllerContext, viewName, masterName, useCache);
    }

我希望能够利用自定义属性将各种“标志”传递给自定义视图引擎。这是可能吗？

Answer 1

public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
{
    var controller = controllerContext.Controller;

    var controllerType = controller.GetType();

    //now we can use reflection
    var attributes = controllerType.GetAttributes();

    // how can I get those parameters here? 

    return base.FindView(controllerContext, viewName, masterName, useCache);
}
