C# DateTime.AddMonth 下个月不存在日期

Question

如果我有 DateTime date = new DateTime("1/31/2010"); 并且我调用 date.AddMonth(1)。我会收到“2/28/2010”还是会因为“2/31/2010”不存在而大吃一惊？或者我会得到“3/3/2010”吗？

(而且我不在装有 Visual Studio 的计算机附近)

Answer 1

• DateTime.AddMonths Method

If the resulting day is not a valid day in the resulting month, the last valid day of the resulting month is used. For example, March 31st + 1 month = April 30th.
