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
    }

}

当我覆盖IActionFilter时，它会提示＆＃39;对象未包含在定义中，那么如何在IActionFilter MVC6中设置ViewBag？

Answer 1

尝试从ActionFilterAttribute继承 我认为您想要的方法签名是OnActionExecuting(ActionExecutingContext)

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