Json的动态解析

JObject jObject = new JObject();
jObject.Add(new JProperty("name", "caixukun"));
jObject.Add(new JProperty("skill", new JObject(new JProperty("id", 1), new JProperty("name", "撩妹"))));
Console.WriteLine(jObject.ToString());
结果：
{
   "name": "caixukun",
　　"skill": {
　　　　"id": 1,
　　　　"name": "撩妹"
　　}
} 

JArray arr = new JArray();
arr.Add(new JValue(1));
arr.Add(new JValue(2));
arr.Add(new JValue(3));
Console.WriteLine(arr.ToString());
结果：
[
　1,
　2,
　3
]
