从jToken获取值
从jToken获取值
提问于 2018-06-21 04:41:07
这是我的情况：
我将JSON字符串解析为JObject。
JObject jObject = JObject.Parse(json);我跳转到JSON中的“白名单”标记
JToken token = jObject.SelectToken("whitelist");我想遍历我的白名单(子)值，进入childs并获取/发送我的值到一个文本框中。循环很好，但是如何读出x的值并将其放入字符串或发送到文本框中？
foreach (JToken x in token)
{
//Want my values from x!
} 对于JObject，我是这样完成的，但我想让它与JToken一起工作：
foreach (var x in jObject)
{
string bulbno = x.Key;
JToken obj = x.Value;
dictionaryBulbs.Add(bulbno, (string)obj["name"]);
} 我的JSON输入：

我会把你的白名单转换成字典。您可以轻松地使用它来获取所需的字符串
var jObj= JObject.Parse(jsonstring);
var result = jObj.SelectToken("whitelist").Children().OfType<JProperty>()
.ToDictionary(p => p.Name, p=> new
{
Created = (DateTime)p.First()["create date"],
Name = (string)p.First()["name"]
