Add string array to a JObject

Question

I tried

JObject obj = new JObject();
obj["item1"] =  new string[] {"a","b"};

and got

Cannot implicitly convert type 'string[]' to 'Newtonsoft.Json.Linq.JToken'

How do I add a string array to a JObject? Also, why do I get that error?

Try this way:

JObject obj = new JObject();
obj.Add("item1", JToken.FromObject(new[] { "a", "b" }));

Thanks it works. I tried obj.Add("item1", JArray.FromObject(new[] { "a", "b" })); too and it worked. What is the difference?

@Johnwebner Basically, a JToken can be an object or an array, a JArray can only be an array

Looks like obj.Add("item1", JToken.FromObject(new[] { "a", "b" })); converts the JToken into a JArray. obj["item1"].GetType(); results in {Name = "JArray" FullName = "Newtonsoft.Json.Linq.JArray"}
