我从 Postman 那里发送了一个请求，它在后端遇到了API。方法的返回类型是JObject。我使用JObject.Parse方法解析字符串。结果得到了一个空数组。注意：NewtonSoft（到版本10）更新已被发布。

// GET /test/custom
[System.Web.Http.ActionName("custom")]
public JObject GetCustom(int Id)
{
        try
        {
         string json = @"{
                  CPU: 'Intel',
                   Drives: [
                    'DVD read/writer',
                    '500 gigabyte hard drive'
                     ]
                     }";
                JObject rtn = JObject.Parse(json);
                return rtn;
                }
        }
        catch (Exception ex)
        {
         return new JObject();
        }
}

此方法返回一个JObject，但 Postman 的响应显示一个空数组。postman response
我还在GetCustom方法中尝试了以下代码，但这些代码也返回空值。

案例：1

dynamic resultObject = new ExpandoObject();
            resultObject.somefield = "somevalue";
            resultObject.someotherfield = 1995;
            return Json(new { status = "success", result = resultObject });

** Package 箱：2**

var jObject = new JObject();
            jObject.Add("someField", "someValue");
            jObject.Add("otherField", 1995);
            var newObj = new { status = "success", result = jObject };
            var returnThis = JsonConvert.SerializeObject(newObj);
            var root = JObject.FromObject(new { sectionData = returnThis });
            return root;

** Package 箱：3**

var cycleJson = JObject.Parse(@"{""name"":""john""}");
            //add surname
            cycleJson["surname"] = "doe";
            //add a complex object
            cycleJson["complexObj"] = JObject.FromObject(new { id = 1, name = "test" });
            return cycleJson;

** Package 箱：4**

var json = @"{
              CPU: 'Intel',
              Drives: [
                'DVD read/writer',
                '500 gigabyte hard drive'
              ]
            }";
            var o = (JObject)JToken.FromObject(json);
            return o;

我正在尝试将第三方API返回的对象序列化为JSON，但我无法控制第三方API或其返回的对象。
