var jsonObject = new JObject();
foreach (var key in Keys)
{
    jsonObject.Add(key, value);
}
jsonObject.Add("*****", "1");

2.  List<JObject>转DataTable

List<JObject> jsons = new List<JObject>();

...

string jsonStr = JsonConvert.SerializeObject(jsons);

2): string转DataTable

DataTable table1 = JsonConvert.DeserializeObject<DataTable>(jsonStr);
