问题 I´m not familiar with JSON data parsing. So far, this is what I´ve come up to through web research: data to parse: https://api.twitch.tv/kraken/streams/ I´m trying to use the JSON.NET/VB.NET framework to do so: Imports Newtonsoft.Json Imports Newtonsoft.Json.Linq '(inside a function) Dim json As JObject = JObject.Parse("https://api.twitch.tv/kraken/streams/") strResult As String = json.SelectToken("streams").SelectToken("game") It´s returning me an error message, and I´m sure I don´t have the

问题 Is it possible to form an object from two classes and then serialize it to JSON, and when deserialize it back be able to get those two objects. say I have: an object of Student and a List<Course> is it possible to combine these two objects in one JSON object. I need this because building up a class for every JSON object would be very exhausting in the project I'm working on! 回答1: Is it possible to form an object from two classes and then serialize it to JSON Yes it is possible to do this just

问题 I'd like to select all elements with a certain match in the name of the property.

问题 I'm attempting to loop through a JArray and I'm getting msg is not declared error inside my for/next loop.

问题 I have read some excellent tutorials on using JSON Web Tokens with ASP.NET Core to authenticate requests to a REST API, however I can find no documentation on whether the more general JSON Web Signature (rfc7515) is supported for use with REST API Definitions to tamper-protect the contents of requests. For example, the following Controller allows a simple POST request whereby a JSON serialized 'CreateRequest' object is submitted to the API and handled: [Produces("application/json")] [Route(

问题 I have been attempting to resolve this issue for several hours. I have tried many approaches and read many posts. I can't seem to find a resolution. I have an object hierarchy whereby I have derived types that contain another derived type. I am using Json.Net's TypeNameHandling setting. I have it set to Auto on both serialization and deserialization. The resulting JSON is: "[\r\n {\r\n \"$type\": \"Common.Monitors.HeartbeatMonitor, Common\",\r\n \"ClassName\": \"HeartbeatMonitor\",\r\n \

问题 I've created a class to parse from json to C# with json.net library, but may be my class has something wrong.
