无法将Web.Http.Results.JsonResult隐式转换为Web.Mvc.JsonResult [英] Cannot implicitly convert Web.Http.Results.JsonResult to Web.Mvc.JsonResult

问题描述

我已经在控制器上设置了此测试方法，以消除任何复杂性.根据我从搜索中发现的所有结果，该方法应该可以工作.我不确定我在这里想念什么.

I've set up this test method on a controller to strip out any complication to it. Based off of all the results I've found from searching this should work. I'm not sure what I'm missing here.

public JsonResult test() 
{
    return Json(new { id = 1 });
}

这是我得到的错误.

不能将类型'System.Web.Http.Results.JsonResult'隐式转换为'System.Web.Mvc.JsonResult'

Cannot implicitly convert type 'System.Web.Http.Results.JsonResult' to 'System.Web.Mvc.JsonResult'

推荐答案

您应该返回JsonResult而不只是Json

you should return a JsonResult instead of just Json

 public JsonResult test() 
    {
        var result = new JsonResult();
        result.Data = new
        {
             id = 1
         };
        result.JsonRequestBehavior = JsonRequestBehavior.AllowGet;
        return result;
    }
