推荐答案

您可以使用System.DateTime类。 http://msdn.microsoft.com/en-us /library/system.datetime.month(v=vs.110).aspx [ ^ ]



它有示例代码。您可以为2个日期创建2个新的System.DateTime实例，然后比较dateTime1.Month和dateTime2.Month以及.Year。



因为它们是日期，还有很多其他方法可以做到这一点，但这将是一个简单的方法。

You can use the System.DateTime class. http://msdn.microsoft.com/en-us/library/system.datetime.month(v=vs.110).aspx[^]

It has example code in there. You can create 2 new instances of System.DateTime of your 2 dates and then compare dateTime1.Month and dateTime2.Month as well as .Year on both.

Because they are dates, there are also many other ways you can do this but this would be a simple way.

DateTime d1 = new DateTime(2014, 9, 19, 7, 0, 0); // 2014-09-19 7:00:00
DateTime d2 = new DateTime(2014, 9, 25, 7, 0, 0); // 2014-09-25 7:00:00

if (d1.Month == d2.Month && d1.Year == d2.Year)
{
    // do what you need
}
