如何将月份名称（字符串）解析为整数以在C＃中进行比较？

Question

我需要能够比较数组中的某些月份名称。

如果有一些直接的方法，那就太好了：

Month.toInt("January") > Month.toInt("May")

我的Google搜索似乎表明唯一的方法是编写自己的方法，但这似乎是一个足够普遍的问题，我认为它已经在.Net中实现，以前有人这样做过吗？

如果使用DateTime.ParseExact()几个人建议的-方法，则应仔细考虑在非英语环境中运行应用程序时要发生的事情！在丹麦，哪个工作ParseExact("Januar", ...)，ParseExact("January", ...)应该工作，哪个应该失败？这将是之间的差异CultureInfo.CurrentCulture和CultureInfo.InvariantCulture。

一种简单的解决方案是使用名称和值创建一个Dictionary。然后使用Contains（）可以找到正确的值。Dictionary<string, string> months = new Dictionary<string, string>(){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "january", "01"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "february", "02"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "march", "03"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "april", "04"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "may", "05"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "june", "06"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "july", "07"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "august", "08"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "september", "09"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "october", "10"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "november", "11"},&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; { "december", "12"},};foreach (var month in months){&nbsp; &nbsp; if (StringThatContainsMonth.ToLower().Contains(month.Key))&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; string thisMonth = month.Value;&nbsp; &nbsp; }}
