问题 I need to create a Json object dynamically by looping through columns. so declaring an empty json object then add elements to it dynamically. eg: List<String> columns = new List<String>{"FirstName","LastName"}; var jsonObj = new {}; for(Int32 i=0;i<columns.Count();i++) jsonObj[col[i]]="Json" + i; And the final json object should be like this: jsonObj={FirstName="Json0", LastName="Json1"}; 回答1: [TestFixture] public class DynamicJson { [Test] public void Test() { dynamic flexible = new

How to configure two JSON serializers and select the correct one based on the route

由 我怕爱的太早我们不能终老 提交于 2020-12-12 06:13:50
问题 I have an ASP.NET Core Web API project using .Net Framework 4.7 and I'm upgrading to .Net Core 3.1. One of the reasons that I'm upgrading is to use the new System.Text.Json serializer. Currently, I have some versions of the API based on the route, like: /api/v1/controller /api/v2/controller And I will create a new one (v3) to use the new serializer. But here is the problem: I want to keep using JSON.Net on the older routes, to avoid any possible formating problem with the integrated clients.

Json.NET vs Newtonsoft.Json SerializationBinder is different

问题 I know there are many similar questions in this topic, yet I did not find my answer here. I have downloaded Json.net in Unity and Newtonsoft.json as a NuGet package in a different project. The Newtonsoft.json is working and I tried to use this working solution in a Unity project. I need to use ISerializationBinder for converting an abstract class hierarchy and I want to serialize/deserialize the classnames only , and not their full assembly name. (Reason for that is that the C# code should

How to ignore false values with System.Text.Json

由 我的梦境 提交于 2020-12-09 03:56:51
问题 I'm migrating from Newtonsoft.Json to System.Text.Json in my .NET Core 3.0 application. I'm trying to ignore false values. In System.Text.Json I found the option to ignore null values: JsonSerializerOptions.IgnoreNullValues = true; But I cannot find the option to ignore false values in System.Text.Json . Does someone know how can this be achieved with System.Text.Json ? Or if someone know the equivalent of Newtonsoft DefaultValueHandling = DefaultValueHandling.Ignore option that would be

从 Asp.Net MVC 到 Web Form

由 与世无争的帅哥 提交于 2020-12-08 08:13:11
从 Asp.Net MVC 到 Web Form 这看起来有点奇怪，大家都研究如何从 Web Form 到 MVC 的时候，为什么会出现一个相反的声音？从研究的角度来说，对反向过程进行研究有助于理解正向过程。通过对 MVC 转 Web Form 的研究，可以推导出：如果想把一个 Web Form 应用转换为 MVC 应用，可能需要进行怎么样的准备，应该从哪些方面去考虑重构？ 当然研究不是我们最真实的目的，项目需要才是非常有力的理由——在我们用 MVC 框架已经初步完成项目第一阶段的时候准备试运行的时候，客户要求必须使用 Web Form——这不是客户的原因，只是我们前期调研得不够仔细。 产生这样的需求有很多历史原因，这不是今天要讨论的范围。我们要讨论的是如何快速的把 MVC 框架改回 Web Form 框架。要完成这个任务，需要做哪些事情？ 在 Web Form 中 渲染 Razor 模板……如果不行，就得按 Razor 重写 Aspx 所有 Ajax 调用的 Controller 都必须改用 Ashx 来实现 MVC 的路由配置得取消，URL 与原始的目录路径结构强相关 前端变化不大，但是要小心 Web Form 对元素 ID 和控件名称（name）的强制处理 Razor 框架 → Aspx 框架 很不幸，没找到现成的工具在 Web Form 框架中渲染 Razor 模板

Newton CamelCase Issue with underscore

由 我的未来我决定 提交于 2020-12-05 12:38:09
问题 I've notice that when I serialize C# dictionary which has key of HTTP_VERB it turn into httP_VERB in the JSON structure instead of hTTP_VERB or http_verb I expected the camel case will make it. This is the code I use to reproduce the issue: class Program { static void Main(string[] args) { var settings = new JsonSerializerSettings(); settings.ContractResolver = new CamelCasePropertyNamesContractResolver(); settings.NullValueHandling = NullValueHandling.Ignore; var headers = new Dictionary
