强制 DateTime.Parse 因固定日期而失败-解网

问：

我将简短地开始，然后在最后提供详细信息。请考虑以下代码：

CultureInfo cultureToTest = new CultureInfo("hu-HU");
Thread.CurrentThread.CurrentCulture = cultureToTest;
DateTime testDateTime = new DateTime(2014,12,13,23,24,25);
String testString = testDateTime.ToString(CultureInfo.InvariantCulture);
DateTime actualDateTime = DateTime.Parse(testString);

问题是，是否有任何可能的值会导致调用引发异常或返回错误值？cultureToTestDateTime.Parse

上下文：

这是一组单元测试。有一个代码主体，在不指定区域性的情况下调用。我担心的是，当此代码在 Invariant 或 en-US 区域性中传递日期时，代码可能会在某些区域性中失败。我建议的解决方案是更改该代码以使用DateTime.Parse

DateTime.Parse(string, CultureInfo.InvariantCulture)

在这些情况下。

为了对更改进行单元测试，我需要使用一种会使原始代码失败的区域性来调用新代码，然后显示更改后的代码将成功。DateTime.Parse(string)

问题是我还没有找到一种文化可以为我做这件事。我打算尝试制造一个，但我想我会先问一个更普遍的问题。

C# CultureInfo 日期时间分析不变文化

StringBuilder sb = new StringBuilder();
foreach (var culture in CultureInfo.GetCultures(CultureTypes.AllCultures))
{
    try
    {
        Thread.CurrentThread.CurrentCulture = culture;
        DateTime testDateTime = new DateTime(2014, 12, 13, 23, 24, 25);
        String testString = testDateTime.ToString(CultureInfo.InvariantCulture);
        DateTime actualDateTime = DateTime.Parse(testString);
        Console.WriteLine(actualDateTime.Day.ToString());
    }
    catch (Exception ex)
    {
       sb.AppendLine(culture.ToString());
    }
}

Console.WriteLine(sb.ToString());

以下区域性在分析该日期时引发异常：
