今天(2012年3月1日)DateTime.Parse失败！ o_0 [英] DateTime.Parse fails for today (01 mar 2012)! o_0

问题描述

今天我遇到了一个非常奇怪的问题.

Today I got a really strange problem.

尝试执行此C#代码:

class Program
{
    static void Main(string[] args)
    {

        string yesterdayString = (DateTime.Now - TimeSpan.FromDays(1)).ToString("R");
        string nowString = DateTime.Now.ToString("R");

        DateTime.Parse(yesterdayString);
        DateTime.Parse(nowString);

        DateTime.Parse("Wed, 29 Feb 2012 18:05:49 GMT"); // this is what i have in yesterdayString
        DateTime.Parse("Thu, 01 Mar 2012 18:05:40 GMT"); // this is what i have in nowString
    }
}

当然，您今天会遇到问题.我添加了最后两个命令，以使您知道问题出在哪里. 明天，整个三月，DateTime.Parse将抛出FormatException(字符串未被识别为有效的DateTime.)

Of course you will get the problem just for today. I've added the last two commands to let you know what the problem is. Tomorrow and throughout the month of March DateTime.Parse will throw a FormatException (String was not recognized as a valid DateTime.)

为什么?

推荐答案

我会说您发现了一个错误.这应该起作用:

I would say you found a bug. This should work:

// 
var spanish = CultureInfo.GetCultureInfo("es");
var date = DateTime.Parse(DateTime.Now.ToString("R", spanish), spanish);

或者对于意大利语，它仍然会抛出...

or for Italian it still throws...

var italian = CultureInfo.GetCultureInfo("it");
var date = DateTime.Parse(DateTime.Now.ToString("R", italian), italian);
