如何在 IActionFilter MVC6 中设置 ViewBag？

Question

public class MAttribute : IActionFilter
{

public void OnActionExecuted(ActionExecutedContext actionContext)
    {
        string searchData = "";
        actionContext.Controller.ViewBag.SearchItem = searchData;
        //object not included in the definition
    }

}

当我重写 IActionFilter 时，它提示 'object not included in the definition'，那么如何在 IActionFilter MVC6 中设置 ViewBag？

Answer 1

尝试从 ActionFilterAttribute 继承我认为你想要的方法签名是 OnActionExecuting(ActionExecutingContext)

编辑：如果您还没有在顶部添加 using Microsoft.AspNetCore.Mvc.Filters;，您可能还想添加。
