<code>JToken</code> is the base class for <code>JObject</code>, <code>JArray</code>, <code>JProperty</code>, <code>JValue</code>, etc. You can use the <code>Children&lt;T&gt;()</code> method to get a filtered list of a JToken's children that are of a certain type, for example <code>JObject</code>. Each <code>JObject</code> has a collection of <code>JProperty</code> objects, which can be accessed via the <code>Properties()</code> method. For each <code>JProperty</code>, you can get its <code>Name</code>. (Of course you can also get the <code>Value</code> if desired, which is another <code>JToken</code>.)

Putting it all together we have:

<pre><code>JArray array = JArray.Parse(json);

foreach (JObject content in array.Children&lt;JObject&gt;())
{
 foreach (JProperty prop in content.Properties())
 {
 Console.WriteLine(prop.Name);
 }
}
</code></pre>

Output:

<pre><code>MobileSiteContent
PageContent
</code></pre>

blocks|key|4678844|text|JObject的默认迭代器是作为字典迭代键/值对。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4678845|JObject+obj+=+JObject.Parse(response);

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

<pre><code>JObject obj = JObject.Parse(response);
foreach (var pair in obj) {
 Console.WriteLine (pair.Key);
}
</code></pre>

{
 var attribute = attributes[attributeProperty.Name];
 var my_data = attribute[&quot;your desired element&quot;];

blocks|key|4678896|text|最简单的方法是查看JSON对象中每个项目的路径。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4678897|For+Each+token+As+JToken+In+json

The simplest way is to look at the path of each item in the JSON object.
<pre><code>For Each token As JToken In json
 Dim key= token.Path.Split(&quot;.&quot;).Last
Next
</code></pre>

blocks|key|4678931|text|如果JToken密钥名称未知，并且您只需要密钥的值而不需要名称，则只需使用JToken.Values()方法即可。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4678932|下面的示例假设JToken值是一个基元类型-提取找到的第一个值。|4678933|解决方案可以扩展为支持数组值。|4678934|JToken+fooToken+=+sourceData.

If the <code>JToken</code> key name is unknown, and you only need the key's Value regardless of name, simply use the <code>JToken.Values()</code> method.
The below sample assumes the <code>JToken</code> value is a primitive type - first value found is extracted. 
Solution can be extended to support Array values.
<pre><code>JToken fooToken = sourceData.

int someNum = fooToken .Values&lt;int?&gt;().First() ?? 0;

int someString = fooToken .Values&lt;string&gt;().First();
</code></pre>

I have some JSON that looks like this

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

I parse this as a JArray:

<pre><code>var array = JArray.Parse(json);
</code></pre>

Then, I loop over the array:

<pre><code>foreach (var content in array)
{

}
</code></pre>

<code>content</code> is a <code>JToken</code>

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

For example, "MobileSiteContent" or "PageContent"

我有一些JSON，看起来像这样[  {    "MobileSiteContent": {      "Culture": "en_au",      "Key": [        "NameOfKey1"      ]    }  },  {    "PageContent": {      "Culture": ...
