ASP.NET(C#)中两日期相减，如何得到相差的月份数？

protected void setTJRQ(string str)
{
DateTime oldTJRQ = DateTime.Parse(str);
DateTime qiantian = DateTime.Now.AddDays(-2);
int diffMonths = qiantian.Month - oldTJRQ.Month;
……
}
这样写太不严谨了~

DateTime startDate = DateTime.Parse("2008-1-1");
DateTime endDate = DateTime.Parse("2010-10-31");
int totalMonth = endDate.Year * 12 + endDate.Month - startDate.Year * 12 - startDate.Month;

C# codeDateTime startDate = DateTime.Parse("2008-1-1");
DateTime endDate = DateTime.Parse("2010-10-31");
int totalMonth = endDate.Year * 12 + endDate.Month - startDate.Year * 12 - startDate.Month;

C# codeDateTime startDate = DateTime.Parse("2008-1-1");
DateTime endDate = DateTime.Parse("2010-10-31");
int totalMonth = endDate.Year * 12 + endDate.Month - startDate.Year * 12 - startDate.Month;

使用TimeSpan就行了，两个日期差就是TimeSpan，然后获取月份值。

SELECT   DATEDIFF(month,   '2000-01-01',   getdate())   AS   months
