分享问一个返回日期天数差的问题
想返回2个datetime之间的天数差，查找了msdn集合只找到了
Dim diff2 As System.TimeSpan
' diff2 gets 55 days 4 hours and 20 minutes.
diff2 = System.DateTime.op_Subtraction(date2, date3)
我只想返回天数差请问有什么函数能直接作天数差的运算么？

Dim a As DateTime
a = "2004-3-31"
Dim b As DateTime
b = "2004-3-25"
Dim c As TimeSpan = a.Subtract(b)
Console.Write(c.Days)
a = "2004-3-31"
Dim b As DateTime
b = "2004-3-25"
Dim c As TimeSpan = a.Subtract(b)
Console.Write(c.Days)

int n=0;
System.TimeSpan n1 =tempstart-tempend ;
n=n1.Days;
////tempstart,tempend是日期
System.TimeSpan n1 =tempstart-tempend ;
n=n1.Days;
////tempstart,tempend是日期

VB的DateDiff函数:DateDiff("d", date2, date3)
