如何使用 JSON.net 枚举嵌套的 JObject？

Question

I have a stringified json object which I parse using JObject.Parse and get the result below-

{{
   "payload": {
       "firstName": "John",
       "lastName": "Doe"
    }
}}

This was my input -

"{ \r\n\"payload\": {\r\n\t\"firstName\":\"John\", \r\n\t\"lastName\": \"Doe\"\r\n }}"

The extra brackets are the start and the end are added by the parser. I want to iterate over this object and display the key value for first name and last name.

foreach (var property in jobject)
{
    Console.WriteLine("  {0}: {1}", property.Name, property.Value);
}

However, I don't know because of the two brackets or because of the nested structure I cannot get to the properties inside. I tried a recursive approach to parse the json but haven't been successful yet. Can someone please help me with this?

If you want to iterate all nested objects as well you can do something like this:

var p = JObject.Parse(...);
foreach (var a in p.DescendantsAndSelf())
{
    if (a is JObject obj)
        foreach (var prop in obj.Properties())
            if (!(prop.Value is JObject) && !(prop.Value is JArray))
                Console.WriteLine("  {0}: {1}", prop.Name, prop.Value);
}

You can use LINQ to access to object. If it is not ok please add the part of parsing object to question.
