Newtonsoft.Json, How to code generic selection

问题

Further on with Newtonsoft.Json, Path returned multiple tokens,

For this code:

JObject o = JObject.Parse(jsStr);
IEnumerable<JToken> selEnum = o.SelectTokens(theFilter);

where the jsStr is the content of https://api.github.com/search/repositories?q=Newtonsoft.Json&sort=stars&order=desc, and theFilter can be any valid JPATH query string (e.g., ".items" or ".items[*].owner").

How to return the selected as a valid json string?

回答1:

It sounds like you just need Json.SerializeObject:

var o = JObject.Parse(jsStr);
var selEnum = o.SelectTokens(theFilter);
var newJson = JsonConvert.SerializeObject(selEnum);

This will give you JSON representing an array of all of the owner values from the original JSON.
