JObject jsonObject=JObject.Parse(theJsonString);
IEnumerable<JToken> jTokens = jsonObject.Descendants().Where(p => !p.HasValues);
Dictionary<string, string> results = jTokens.Aggregate(new Dictionary<string, string>(), (properties, jToken) =>
{
properties.Add(jToken.Path, jToken.ToString());
return properties;
});
I had the same requirement of flattening a nested json structure to a dictionary object. Found the solution here.
