[c#] Getting the name / key of a JToken with JSON.net

I have some JSON that looks like this

[
  {
    "MobileSiteContent": {
      "Culture": "en_au",
      "Key": [
        "NameOfKey1"
      ]
    }
  },
  {
    "PageContent": {
      "Culture": "en_au",
      "Page": [
        "about-us/"
      ]
    }
  }
]

I parse this as a JArray:

var array = JArray.Parse(json);

Then, I loop over the array:

foreach (var content in array)
{

}

content is a JToken

How can I retrieve the "name" or "key" of each item?

For example, "MobileSiteContent" or "PageContent"

JObject obj = JObject.Parse(json);
var attributes = obj["parent"]["child"]...["your desired element"].ToList<JToken>(); 

foreach (JToken attribute in attributes)
{   
    JProperty jProperty = attribute.ToObject<JProperty>();
    string propertyName = jProperty.Name;
}

The default iterator for the JObject is as a dictionary iterating over key/value pairs.

JObject obj = JObject.Parse(response);
foreach (var pair in obj) {
    Console.WriteLine (pair.Key);
}
