json.net

问题 I have a following JSON . I have added 2 x double quotes so that I could declare it as string variable in c# , in reality it contains one times double quotes for properties. The complete example code is in this fiddle. I am using Newtonsoft but can use System.Text.Json as well so a working solution for either will be appreciated. { ""display"": ""wizard"", ""settings"": {}, ""components"": [ { ""title"": ""Activity Information"", ""label"": ""Activity Information"", ""type"": ""Activity"", "

问题 I have a custom class that looks like this: public class PartnerLoginOptions { public string Username { get; set; } public string Password { get; set; } public string DeviceModel { get; set; } public string Version { get; set; } public bool? IncludeUrls { get; set; } public bool? ReturnDeviceType { get; set; } public bool? ReturnUpdatePromptVersions { get; set; } } I'd like to ignore any bool? members with default values when serializing, but keep strings with null values. For example, if I

问题 in my .net Core 3.0 Api the [JsonIgnore] Attribute is not working as excepted. Im using System.Text.Json instead of the old Newtonsoft.Json When i'm using my resource that returns a list of Objects, for example: /api/Object/ the objects are serialized like this: [ { "id": 1, "date": "2020-02-12T08:45:51.502", "userId": 1, "tags": [ { "name": "string" } ] } ] But when I request a single result /api/Object/{id} the full object gets serialized like this: { "user": { "hasAccess": false, "id": 1,

问题 I've a simple relational model with a Parent and Child relation as follows: public class Parent { public Parent(int id) { Id = id; } public int Id { get; private set; } public IList<Child> Children { get; set; } = new List<Child>(); } public class Child { public Parent Parent { get; set; } } I create a small object graph consisting of a list of two children who share the same parent: var parent = new Parent(1); var child1 = new Child {Parent = parent}; var child2 = new Child {Parent = parent}

问题 How do i define key value pairs object in json schema (the "correct" way) ? i want to define this: "id" : 99, _info : { "name" : "somename", "href" : "someUrl" } Are any of the following two accurate?: 1) { "type": "object", "name": "MyObj", "properties": { "id": { "type": "integer" }, "_info": { "type": "array", "items": { "type": "object" "properties": { "key": { "type": "string", "description": "key" }, "value": { "type": "string", "description": "the value" } } } } } } 2) { "type":

问题 Currently I'm facing the following issue when I try to deserialize a json string that I receive from a 3rd party (--> I cannot change the received json string by myself) with Newtonsoft.Json : The json contains a dictionary (and some other entries that I don't list here): "food": { "Menu 1": "abc", "Menu 2": "def" } I've created a class that contains the property (plus the properties that I didn't list here): Dictionary<string, string> Food {get; set;} In this case the desiralization of the

问题 While I was deserializing some JSON data to DataSet, the resultant dataset may lose its column schema. that means, When I deserialize some JSON, it populates the Dataset with Int64 objects rather than Int32. I would like it to choose Int32. I know, Json.NET by default reads integer values as Int64 because there is no way to know whether the value should be Int32 or Int64. JsonSerializerSettings settings = new JsonSerializerSettings() { Converters = { new PrimitiveJsonConverter() }, }; DataSet

问题 When serializing objects using the Netwonsoft.JSON library, it's possible to specify the output order using JsonPropertyAttribute property Order . However, I would like to also sort alphabetically the properties by default on top of that. 回答1: You can actually control the order by implementing IContractResolver or overriding the DefaultContractResolver's CreateProperties method. Here's an example of my simple implementation of IContractResolver which orders the properties alphabetically:
