C# DateTime.AddMonth with day non-existent in next month
Question
If I have DateTime date = new DateTime("1/31/2010"); and I call date.AddMonth(1) . Will I get "2/28/2010" or will it freak out because "2/31/2010" doesn't exist? Or will I get "3/3/2010"?
(Also I'm not near a computer with Visual Studio)

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.

你会得到下个月的结束日，所以2月28日。
