How to find the key for a JSON value

I have a JSON string "{name :\"daijiepei\"}". I'm using a JObject to deserialize it: 

JObject json = JObject.Parse(str);
string value = obj["name"];

So I can get the value, but I can't get the JSON key. How do I get the key for a JSON value?

You can iterate through the Properties method of JObject and get the Key property from there. Example code from the documentation.

JObject o = new JObject
{
    { "name1", "value1" },
    { "name2", "value2" }
};

foreach (JProperty property in o.Properties())
{
    Console.WriteLine(property.Name + " - " + property.Value);
}
// name1 - value1
// name2 - value2

foreach (KeyValuePair<string, JToken> property in o)
{
    Console.WriteLine(property.Key + " - " + property.Value);
}
// name1 - value1
// name2 - value2
