Fixing JSON Date serialization from .Net web method
提问by Justin
I am currently working on a project where I am sending a .Net type via ajax to a client application via ajax. I have no issues with the object being serialized and set to the client.
我目前正在开发一个项目，我通过 ajax 将 .Net 类型通过 ajax 发送到客户端应用程序。我对被序列化并设置为客户端的对象没有任何问题。
I run into issues when I take the exactly same object and post it back to the server via a web method with the following error: /Date(1373950800000)/ is not a valid value for DateTime.Which is pretty annoying as that is how Microsoft gave it to me, but that's besides the point.
当我获取完全相同的对象并通过 Web 方法将其发回服务器时遇到了以下错误：/Date(1373950800000)/ is not a valid value for DateTime.这很烦人，因为 Microsoft 是这样给我的，但这不是重点。
Does anyone have a quick fix for this? I want a seamless way this can be accomplished without having to change the object right before returning it from the ajax call.
有没有人可以快速解决这个问题？我想要一种无缝的方式来实现这一点，而不必在从 ajax 调用返回它之前更改对象。

Your issue comes down to the server-side JavaScript serializer you are using; either JsonDataContractSerializer(default serializer for ASP.NET MVC) or NewtonSoft Json Serializer(default serializer for ASP.NET Web API).
您的问题归结为您使用的服务器端 JavaScript 序列化程序；无论是JsonDataContractSerializer（ASP.NET MVC的默认的序列）或NewtonSoft Json Serializer（对于的ASP.NET Web API默认的序列）。

This is the method that I use for these things:
这是我用于这些事情的方法：
First you need to clean the junk out of the date parameter
首先你需要清除日期参数中的垃圾
String unixDate = "/Date(1373950800000)/";
unixDate = unixDate.Replace("/Date(","").Replace(")/", "");
Now, as .NET and unix measure time in a different way, you have to compensate for that by creating a date set to the 1st of Jan 1970 and then adding the numeric part of the date that you were passed
现在，由于 .NET 和 unix 以不同的方式测量时间，您必须通过创建一个设置为 1970 年 1 月 1 日的日期，然后添加您通过的日期的数字部分来弥补这一点
DateTime dotNetDate = new DateTime(1970, 1, 1);
dotNetDate = dotNetDate.AddMilliseconds(Convert.ToInt64(unixDate)
You should also note that there will a loss of precision here - .NET dates are to the nearest nanosecond where unix dates are to the nearest millisecond
您还应该注意，这里会丢失精度 - .NET 日期精确到纳秒，而 unix 日期精确到毫秒

Try sending the dates with the forward slashes escaped. I have an iPad client that posts JSON to an ASP.NET WebAPI service method and we have to send dates this way:
尝试发送带有转义斜杠的日期。我有一个 iPad 客户端，它将 JSON 发布到 ASP.NET WebAPI 服务方法，我们必须以这种方式发送日期：
"due": "\/Date(1335830400000)\/"
"due": "\/Date(1335830400000)\/"

Handle the DateFormat while serialization following code will resolve your problem
处理 DateFormat 而序列化以下代码将解决您的问题
JsonConvert.SerializeObject(yourobject, Formatting.Indented,
new JsonSerializerSettings
{
DateFormatHandling = DateFormatHandling.IsoDateFormat
});
It will result the dates in 2009-02-15T00:00:00Z format
它将导致 2009-02-15T00:00:00Z 格式的日期
