在MVC控制器中将实体添加到JSON

问题描述

我想将模型的模拟实体作为新实体添加到现有json中.在此代码示例中:如何将 model2 添加到 js ?

I would like to add an mock entity of my model to an existing json as a new entity. In this code example: how can I add model2 to js?

public JsonResult Get()
    {
      Employee model1 = new Employee();
      Employee model2 = new Employee();

      model1.id = 1;
      model1.name = "Fritz";
      model2.id = 2;
      model2.name = "Emil";

      JsonResult js = new JsonResult(model1);

      return js;
    }

推荐答案

您可以创建Employee对象的列表/数组，并将2个对象(model1和model2)添加到该列表中并发送该列表.

You can create a list/array of Employee objects and add your 2 objects (model1 and model2) to that list and send the list.

public JsonResult Get()
{
    var model1 = new Employee();
    model1.id = 1;
    model1.name = "Fritz";

    var model2 = new Employee();
    model2.id = 2;
    model2.name = "Emil";

    var list= new List<Employee> { vmodel1, model2 };
    return Json(list);
}

如果此操作方法是HttpGet类型，则在使用JsonRequestBehavior枚举调用Json方法时，应明确指定该方法.

If this action method is HttpGet type, you should explicitly specify that when calling the Json method by using the JsonRequestBehavior enum.

return Json(list,JsonRequestBehavior.AllowGet);

这将返回如下响应.包含两个项目的数组.

This will return a response like below. An array of two items.

[{"id":1,"name":"Fritz"},{"id":2,"name":"Emil"}]

我还建议您将PascalCasing用于类属性名称. Id和Name而不是id和Name

I also suggest you to use PascalCasing for the class property names. Id and Name instead of id and Name
