Datatables JSONRequestBehavior.AllowGet不工作

我在jquerydatatables服务器端工作。创建json对象时，要返回，它不允许JSONRequestBehavior.AllowGet。若代码和下面的代码完全相同，那个么我就无法在客户端获取数据

HTML:

服务器端：

但是如果我把它放在下面

var result =  Json(new
            {   draw = draw,
                recordsFiltered = totalRecords,
                recordsTotal = totalRecords,
                data = data
            },JsonRequestBehaviour.AllowGet);

然后我在mvc核心中找不到这个东西。请帮助我该怎么做。

在asp.net core中，没有采用

JsonRequestBehavior

的重载。因此，您可以简单地使用要传递的数据调用

Json

方法

var result =  Json(new
            {   draw = draw,
                recordsFiltered = totalRecords,
                recordsTotal = totalRecords,
                data = data
            });
return result;

什么特别不起作用？您是否遇到编译/运行时错误？这是什么错误？例外情况的详细信息是什么？我从您那里得到了解决方案，非常感谢
