asp.net 从jToken获取值

我情况是这样的：
我将JSON字符串解析为JObject。

JObject jObject = JObject.Parse(json);

跳转到JSON中的“whitelist”标记

JToken token = jObject.SelectToken("whitelist");

我想循环我的白名单（子）值，进入查尔兹并获取/发送我的值到一个文本框。循环是好的，但我如何读出x的值，并把它们放入一个字符串或发送到一个文本框？

foreach (JToken x in token)
{
   //Want my values from x!
}

使用JObject时，我可以这样完成，但我希望使用JToken时也能这样：

foreach (var x in jObject)
{
    string bulbno = x.Key;
    JToken obj = x.Value;
    dictionaryBulbs.Add(bulbno, (string)obj["name"]);
}

我的JSON输入：

我将把你的 whitelist 转换成字典，你可以很容易地用它来得到你想要的字符串

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"]
                });

埃塞尔的答案当然是好的，但一个更简化的答案可能如下：

var jTokenProperties = jToken.Children().OfType<JProperty>();
foreach (JProperty property in jTokenProperties)
{
    var key = property.Name;
    var value = property.Value;
}

其中jToken被假定为现有的JToken对象。
诀窍是使用JProperty，首先将Children()转换为可枚举的JProperty。
