问题 I'm trying to serialize/deserialize a Dictionary<string, object> which seems to work fine if the object is a simple type but doesn't work when the object is more complex. I have this class: public class UrlStatus { public int Status { get; set; } public string Url { get; set; } } In my dictionary I add a List<UrlStatus> with a key of "Redirect Chain" and a few simple strings with keys "Status", "Url", "Parent Url". The string I'm getting back from JSON.Net looks like this: {"$type":"System

问题 I'm getting some very weird behaviour in my Xamarin.Forms Project. I'm retrieving some serialized data from a REST API. I'm then trying to use Json.NET to deserialize that to an object. This works perfectly fine on Android and if I copy the code to a .NET console application it also works. However in my iOS project, the call to .DeserializeObject() just returns null. It doesn't throw an error or complain in any way. I did find this discussion: https://forums.xamarin.com/discussion/15152

问题 I am trying to use the NETFx Json.NET MediaTypeFormatter nuget package to swap out the default DataContractJsonSerializer in my WCF REST service (4.0 framework). I downloaded the package in my project and added the following lines of code in the Global.asax file. void Application_Start(object sender, EventArgs e) { RegisterRoutes(); // Create Json.Net formatter serializing DateTime using the ISO 8601 format var serializerSettings = new JsonSerializerSettings(); serializerSettings.Converters

问题 I'm working in an ASP.NET webapi codebase where we rely heavily on the automatic support for JSON deserialization of message bodies into .NET objects via JSON.NET. As part of building out patch support for one of our resources, I'd very much like to distinguish between an optional property in the JSON object that's not present, vs. that same property that's explicitly to null. My intention is to use the first for "don't change what's there" vs. "delete this thing." Does anyone know if it's

问题 I have the following JSON text: { "PropOne": { "Text": "Data" } "PropTwo": "Data2" } I want to deserialize PropOne into type PropOneClass without the overhead of deserializing any other properties on the object. Can this be done using JSON.NET? 回答1: public T GetFirstInstance<T>(string propertyName, string json) { using (var stringReader = new StringReader(json)) using (var jsonReader = new JsonTextReader(stringReader)) { while (jsonReader.Read()) { if (jsonReader.TokenType == JsonToken

问题 I am using a jQuery plugin that need a JSON object with following structure(I will be retrieving the values from database): { results: [ { id: "1", value: "ABC", info: "ABC" }, { id: "2", value: "JKL", info: "JKL" }, { id: "3", value: "XYZ", info: "XYZ" } ] } Here is my class: public class results { int _id; string _value; string _info; public int id { get { return _id; } set { _id = value; } } public string value { get { return _value; } set { _value = value; } } public string info { get {

问题 I'm downloading the JSON using System.Net.WebClient.DownloadString. I'm getting a valid response: { "FormDefinition": [ { "$id":"4", "Class":558, "ClassDisplayLabel":"Punchworks", "Name":"Punchworks Form" }, { "$id":"6", "Class":558, "ClassDisplayLabel":"Punchworks", "Name":"Punchworks Form test second" }, { "$id":"46", "Class":558, "ClassDisplayLabel":"Punchworks", "Name":"any_Name" }, { "$id":"47", "Class":558, "ClassDisplayLabel":"Punchworks", "Name":"Punchworks Form test second" }, { "$id

问题 I am trying to understand how JsonConvert.DeserializeObject<X>(someJsonString) is able to set the values by using the constructor. using Newtonsoft.json public class X { [JsonProperty("some_Property")] public string SomeProperty {get;} [JsonProperty("some_Property_2")] public string SomeProperty2 {get;} public X(string someProperty, string someProperty2) { SomeProperty = someProperty; SomeProperty2 = someProperty2; } public static X parseObject(string parseThisJson) { JsonConvert
