问题 TL;DR; "I like how my generated AutoRest client deserializes my main entities when dealing with the 200 scenarios.. but, MUST I manually parse the 400 scenarios?", said the lazy programmer DETAILS: So, I have an API, (Web API 2), and I do all the standard stuff.. using POCO's that implement IValidatable in addition to property-level validation using System.Data.DataAnnotations my Web API returns 400 errors like this (just an example): if (!ModelState.IsValid) { return BadRequest(ModelState);

问题 I want to serialize properties but with each property enclosed in a separate JSON object in an array. Example below: public class Metadata { public string Name { get; set; } public Guid Id { get; set; } } public void SerializeCars() { var data = new Metadata { Name = "MyName", Id = Guid.NewGuid() }; var json = JsonConvert.SerializeObject(data, Formatting.Indented); } Current result will be: { "Name": "MyName", "Id": "f9c4bc06-0b99-47ff-b22b-ea094fc188ee" } I want it to be (missing "td" class

问题 I have two classes, where the concrete class Model<T> hides the base class' Items property. class Model { List<ListItem> Items {get;set;} } class Model<T> : Model { new List<ListItem<T>> Items {get;set;} } Upon serializing an instance of Model<T> with Json.NET I get the error: Newtonsoft.Json.JsonSerializationException : A member with the name ' Items ' already exists on ' Model<T> '. Use the JsonPropertyAttribute to specify another name. I understand why I'm receiving this error, however, I

问题 I want to modify JSON.NET so that when I am serializing a Model from my API it sends only an array of IDs for a composite Collection object. For example: class Employee { public ICollection<Address> Addresses { get; set; } } class Address { public int id; public string location; public string postcode; } Then when I send that back through WebApi Request.Createresponse(HttpStatusCode.OK, new Employee()); Instead of this: { "Addresses" : [ {"id" : 1, "location" : "XX", "postcode" : "XX" }, {"id

问题 I have a list of objects that I want to serialize as JSON like below, since there is a complex type in this list. I want to change this complex type to Key/Value pairs where each Key is the name of a property in the type, and each Value is the corresponding value of that property. I've tried multiple solutions but none of them worked for me. Here is the object structure public class Metadata { public string FirstName { get; set; } public string LastName { get; set; } } public class Data { //

问题 I want to send a bunch of data, converted to json, as a string, to a Web API POST method. I can send a simple string just fine, but when I try to send stringified json data, the method is not even reached - apparently the complex string is not viewed as a valid string value or something. This works, when passing "randomString" from the client: Web API [Route("{unit}/{begindate}/{enddate}/{stringifiedjsondata}")] [HttpPost] public void Post(string unit, string begindate, string enddate, string

问题 I recently solved this error: Type is an interface or abstract class and cannot be instantiated , by using the solution suggested here: Using Json.NET converters to deserialize properties. Unfortunately I am getting new issues with this. In the code below, Depth gets called as part of the deserialisation, which in turn calls the Prof property which fails because 'this.Profile' is null. ('this.Profile' is a property inherited from the Section class.) public class TimberSection : Section,

问题 I am using below (http://james.newtonking.com/projects/json) to force XML nodes to be an array when converted to JSON: <person xmlns:json='http://james.newtonking.com/projects/json' id='1'> <name>Alan</name> <url>http://www.google.com</url> <role json:Array='true'>Admin</role> </person> and what I get is { "person": { "@id": "1", "name": "Alan", "url": "http://www.google.com", "role": [ "Admin" ] } } What I wanted is { "person": [ { "@id": "1", "name": "Alan", "url": "http://www.google.com",

问题 I am trying to create dynamic JSON using ExpandoObject and IDictionary. During the dynamic creation of JSON there could be instances when the Name or Value would repeat. However when adding the repeated Name or Value to the ExpandoObject, it gives an error: An item with the same key has already been added. Below is my code snippet : DataTable dt_MappedColumns = (DataTable)ViewState["MappedColumns"]; dynamic ManCols = new ExpandoObject(); var dictionary1 = (IDictionary<string, object>)ManCols;

问题 I have problem with Newtonsoft.JsonConverter in my C# app. I have decimal with trailing zeros. After convert to json - there zeros are missing. Example: input (decimal): 1.99000 output (json): 1.99 I have my own converter, that handles decimal value. Also, I configured FloatParseHandling as decimal. What can I do to preserve this process? 回答1: This was a bug introduced in Json.NET 10.0.1 and reported here. It has since been fixed in 11.0.1. 来源： https://stackoverflow.com/questions/46684557
