DateTime与DateTimeOffset

阅读更多关于 DateTime与DateTimeOffset

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 目前，我们有一种以TimeZone感知方式处理.net DateTimes的标准方法：每当我们生成一个 DateTime 我们用UTC（例如使用 DateTime.UtcNow ）来做，每当我们显示一个时，我们就会从UTC转换回用户的当地时间。这工作正常，但我一直在阅读有关 DateTimeOffset 以及它如何捕获对象本身的本地和UTC时间。所以问题是，使用 DateTimeOffset 与我们已经做的事情有什么好处？ #1楼来自微软： DateTimeOffset值的这些用法比DateTime值的用法更常见。因此，应将DateTimeOffset视为应用程序开发的默认日期和时间类型。来源： “在DateTime，DateTimeOffset，TimeSpan和TimeZoneInfo之间选择” ， MSDN 我们使用 DateTimeOffset 几乎所有内容，因为我们的应用程序处理特定时间点（例如，创建/更新记录时）。另外，我们也在SQL Server 2008中使用 DATETIMEOFFSET 。当你想要只处理日期，只处理时间或者在一般意义上处理时，我认为 DateTime 是有用的。例如，如果你有，你要每天都去送行上午7时报警，你可以存储在一个 DateTime 利用

Setting IgnoreSerializableAttribute Globally in Json.net

问题 I'm working on a ASP.NET WebApi (Release Candidate) project where I'm consuming several DTOs that are marked with the [Serializable] attribute. These DTOs are outside of my control so I'm not able to modify them in any way.

阅读更多关于 Conditional member serialization based on query parameter?

I mainly want to do this to reduce bandwidth on GETs without causing a proliferation of ViewModel classes. For example: GET /books/1?format=summary public class Book { [SerializeFormat("summary")] public int Id { get; set; } [SerializeFormat("summary")] public string Title { get; set; } public string Contents { get; set; } } or

阅读更多关于 Web API: Configure JSON serializer settings on action or controller level

问题 Overriding the default JSON serializer settings for web API on application level has been covered in a lot of SO threads. But how can I configure its settings on action level? For example, I might want to serialize using camelcase properties in one of my actions, but not in the others. 回答1: Option 1 (quickest) At action level you may always use a custom JsonSerializerSettings instance while using Json method: public class MyController : ApiController { public IHttpActionResult Get() { var
