C#JSON格式数据的转换

json格式字符串转化为json对象：
JObject calculate = (JObject)JsonConvert.DeserializeObject(Rep.Request["data"].ToString());
或者
JArray calculate = (JArray)JsonConvert.DeserializeObject(Rep.Request["data"].ToString());

JSON对象转化为json字符串：
string strResult = JsonConvert.SerializeObject(dtResult);

JArray是数组数据[{},{},{}]，里面可以有多个JObject
JObject是json数据{}

取出里面的key和value用JToken
JObject json = //获得一个JObject对象
/*

StringBuilder sb = new StringBuilder("<div>");

foreach(JProperty jp in record)
{
sb.Append(String.Format(@"<span>{0}</span>：<span>{1}</span>"
,jp.Name
,jp.Value));
