请教取两个日期变量的值应该如何取

请问取两个日期变量的值应该怎么取?
比如说2007-1-1减去2006-1-1要等于1年要怎么取?

[解决办法]
DateTime A = DateTime.Parse( "2007-1-1 ");
DateTime B = DateTime.Parse( "2006-1-1 ");
TimeSpan T = new TimeSpan(A.Ticks - B.Ticks);

Text = (T.TotalDays / 365).ToString();

[解决办法]
DateTime A = DateTime.Parse( "2007-1-1 ");
DateTime B = DateTime.Parse( "2006-1-1 ");
TimeSpan T = new TimeSpan(A.Ticks - B.Ticks);

再取 T 里面的年属性就行了
[解决办法]
DateTime A = DateTime.Parse( "2007-1-1 ");
DateTime B = DateTime.Parse( "2006-1-1 ");
int i = A.Year - B.Year;
