How do you merge 2 JObjects in Json.Net?

Question

Background: I am trying to serialize my data into Json and return it from my MVC controller and I want to merge 2 C# data objects into a single json result. I have overridden JsonResult to use JsonConvert.SerializeObject which works for 1 object. By I want to merge 2 C# objects into 1 json result.

Answer 1

In Json.Net 4.5:

JObject o1 = JObject.FromObject(data, serializer);
JObject o2 = JObject.FromObject(data2, serializer);
foreach (var i in o2)
{
    o1.Add(i.Key, i.Value);
}

In Json.Net 6:

JObject o1 = JObject.FromObject(data, serializer);
JObject o2 = JObject.FromObject(data2, serializer);
o1.Merge(o2, new JsonMergeSettings
{
    // union array values together to avoid duplicates
    MergeArrayHandling = MergeArrayHandling.Union
});
