string jsonObject = "{\"phone\":\"12345678900\",\"codeType\":\"register\"}";
JObject jo = JObject.Parse(jsonObject);
jo.Add("test", "111");//新增
jo["phone"] = "123456";//修改
jo.Remove("codeType");//删除
//JObject遍历json的key和value
foreach (var item in jo)
{
Console.WriteLine(item.Key + ":" + item.Value + ",");
}
//JArray遍历
string jsonArray = "[{'a':'a1','b':'b1'},{'a':'a2','b':'b2'}]";
JArray ja = JArray.Parse(jsonArray);
foreach (JObject j in ja)
{
foreach (var item in j)
{
Console.WriteLine(item.Key);
}
}
//json嵌套
string jsonText = "{\"beijing\":{\"zone\":\"海淀\",\"zone_en\":\"haidian\"}}";
jo = JObject.Parse(jsonText);
Console.WriteLine("key取值：" + jo["beijing"]["zone"] + ";索引：" + ja[0]["a"]);
