设置默认日期时间格式c# [英] Set Default DateTime Format c#
问题描述
是否有一种设置或覆盖整个应用程序的默认DateTime格式的方法。我正在C#.Net MVC 1.0中编写一个应用程序,并使用大量的泛型和反射。如果我可以将默认的DateTime.ToString()格式替换为dd-MMM-yyyy,将会更简单。我不希望这个格式在不同机器上运行时更改。
Is there a way of setting or overriding the default DateTime format for an entire application. I am writing an app in C# .Net MVC 1.0 and use alot of generics and reflection. Would be much simpler if I could override the default DateTime.ToString() format to be "dd-MMM-yyyy". I do not want this format to change when the site is run on a different machine.
编辑 -
只是为了澄清我的意思是专门调用ToString,而不是一些其他的扩展功能,这是因为反射/生成的代码。将更容易更改ToString输出。
Edit - Just to clarify I mean specifically calling the ToString, not some other extension function, this is because of the reflection / generated code. Would be easier to just change the ToString output.
推荐答案
datetime的默认格式是:
The "default format" of a datetime is:
ShortDatePattern + ' ' + LongTimePattern
至少在目前的单声道实施。
如果你想显示像2001-02-03T04:05:06Z这样的日期和时间,那么这是非常痛苦的,即 ISO 8606 ,但不是您的案例中的一个大问题:
at least in the current mono implementation. This is particularly painful in case you want to display something like 2001-02-03T04:05:06Z i.e. the date and time combined as specified in ISO 8606, but not a big problem in your case:
using System;
using System.Globalization;
using System.Threading;
namespace test {
public static class Program {
public static void Main() {
CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
culture.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";
culture.DateTimeFormat.LongTimePattern = "";
Thread.CurrentThread.CurrentCulture = culture;
Console.WriteLine(DateTime.Now);
}
}
}
这将设置默认行为的ToString数据时间返回您期望的格式。
This will set the default behavior of ToString on datetimes to return the format you expect.
