问题 One way of deserializing interface and abstract properties is a class is by setting TypeNameHandling to Auto during serialization and deserialization. However, when I try the same when serializing and deserializing an interface object directly, it does not work - interface ISample { string Key { get; set; } } class A : ISample { public string Key { get; set; } public A(string key) { this.Key = key; } } class B : ISample { public string Key { get; set; } public B(string key) { this.Key = key;

问题 How to print any arbitrary variable in C# so as to print all members? I found three answers with the same technique: https://stackoverflow.com/a/26181763/2125837 which suggests serializing with Json.NET among other answers, and https://tech.io/playgrounds/2098/how-to-dump-objects-in-c/using-json-and-yaml-serializers, https://www.codeproject.com/Articles/1194980/How-to-Dump-Object-for-Debugging-Purposes-in-Cshar However, when I tried it out, with the following code, using System; using System

问题 I want to modify my json.NET serializer to add the $type property only to the objects which implements a given interface but not to any property or nested objects. With TypeNameHandling.Auto (default) { "PropertyA": 123, "PropertyB": "foo", "PropertyC": [1, 2, 3, 4] } With TypeNameHandling.All { "$type": "JsonNetTypeNameHandling.TestEvent, jsonNetTypeNameHandling", "PropertyA": 123, "PropertyB": "foo", "PropertyC": { "$type": "System.Collections.Generic.List`1[[System.Int32, mscorlib]],

问题 I have some JSON data that looks like this: { "910719": { "id": 910719, "type": "asdf", "ref_id": 7568 }, "910721": { "id": 910721, "type": "asdf", "ref_id": 7568 }, "910723": { "id": 910723, "type": "asdf", "ref_id": 7568 } } How can I parse this using JSON.net? I can first do this: JObject jFoo = JObject.Parse(data); I need to be able to iterate over each object in this list. I would like to be able to do something like this: foreach (string ref_id in (string)jFoo["ref_id"]) {...} or

问题 I have a class with two DateTime properties. I need to serialize each of the properties with a different format. How can I do it? I tried: JsonConvert.SerializeObject(obj, Formatting.None, new IsoDateTimeConverter {DateTimeFormat = "MM.dd.yyyy"}); This solution doesn't work for me because it applies date format to all the properties. Is there any way to serialize each DateTime property with different format? Maybe there is some attribute? 回答1: NewtonSoft.Json has a structure that's a bit

问题 I have globally explicitly configured my MVC4 app to use the JSON.NET serializer . I know i have the choice of using the ISO standard dates or the old Microsoft date format when serializing dates. But how can i output my own custom dateTime format string ,like :"dd/MM/yyyy hh:mm". I could do this in MVC3 when plugging in Json.NET as the default serializer but cant seem to do it in MVC4 . So far in the application_start i have done : var settings = GlobalConfiguration.Configuration.Formatters

问题 We have a JSON object with one of the object having a dash in its name.

问题 I have an object with predefined data structure: public class A { public string Id {get;set;} public bool? Enabled {get;set;} public int? Age {get;set;} } and JSON is supposed to be { "Id": "123", "Enabled": true, "Age": 23 } I want to handle JSON error in positive way, and whenever server returns unexpected values for defined data-types I want it to be ignore and default value is set (null). Right now when JSON is partially invalid I'm getting JSON reader exception: { "Id": "123", "Enabled":
