具有JObject元素的C＃JsonResult返回空数组

Question

I am trying to return a JSON result from a REST API that includes a JsonObject as an element.

var aJsonObject = new JObject();
aJsonObject.Add("somefield", "somevalue" );
aJsonObject.Add("someotherfield", 1995);

return Json( new { status = "success", result = aJsonObject } );

The client receives an empty nested arrays:

{"status":"success","result":[[[]],[[]]]}

My work around, which I don't love, is to serialize the JsonObject, thus sending it as a string and then having the client parse it. It works, but it's a bit ugly.

Is this a bug or am I doing it wrong?

NOTE: 8/3/18 I edited the variable declaration to correct a typo - it was jsonObject and should have been aJsonObject

Answer 1

JObject is already json-formatted. Main purpose of JsonResult is to serialize an object to json. What you are trying to do is (I guess):

dynamic resultObject = new ExpandoObject();
resultObject.somefield = "somevalue";
resultObject.someotherfield = 1995;

return Json( new { status = "success", result = resultObject } );

If you want to build the Json string yourself and return it to the client you can use Content:

return new Content(yourjsonstring, "application/json");

And if you want to keep using JObject, this works (and then return the JSON as @ozum.e describes):

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