How can I generate all possible LINQ strings of a json object for Json.net?

Question

In json.net we can using linq to json based on this tutorial.

I want to know is there any way to generate a string query or not? Consider this json example:

You can use SelectTokens("..*") to recursively descent the JSON token hierarchy, where ".." is the JSONPath recursive descent operator and "*" is a wildcard matching anything. Then you can use JToken.Path as your dictionary key:

var dic = linq.SelectTokens("..*")
    .ToDictionary(t => t.Path, t => t.ToString());

Note this includes the root token. If you want to skip it, do:

var dic = linq.SelectTokens("..*")
    .Where(t => t != linq)
    .ToDictionary(t => t.Path, t => t.ToString());

You could also use JContainer.DescendantsAndSelf() or JContainer.Descendants() to do the recursive descent, filtering out all JProperty nodes for the same result:

var dic = linq.Descendants()
    .Where(t => t.Type != JTokenType.Property)
    .ToDictionary(t => t.Path, t => t.ToString());
