遍历 JObject 得到属性 Name

Question

正如标题中简要描述的那样，我试图循环遍历 JObject 以获取内部键的所有名称，但是如您所见，这是在 sub-key "Bayonet" 下指定的。虽然这很好用，我需要一个更通用的方法，因为 "Bayonet" 子项不会总是存在。以下是我的一些尝试：

可行但未推广的解决方案：

foreach (JProperty condition in SkinData[Skin]["Bayonet"])
{
     conditionlines.Add(condition.Name);
}

无法将 JObject 转换为 JProperty 错误：

foreach (JProperty condition in SkinData[Skin].First)
{
    conditionlines.Add(condition.Name);
}

因无名称字符串错误而失败：

foreach (JProperty condition in SkinData[Skin][0])
{
    conditionlines.Add(condition.Name);
}

你可以这样做：

foreach (var condition in ((JContainer)SkinData[Skin]).Descendants().OfType<JObject>().Take(1).Properties())
{
     conditionlines.Add(condition.Name);
}

这会找到第一个 descendant (if any) of the token specified by Skin that is of type JObject, then loops through its properties。
