计算两个日期之间的月数

Question

我有以下VB.NET代码：

Dim Date1 As New DateTime(2010,5,6)
Dim Date2 As New DateTime(2009,10,12)
Dim NumOfMonths = 0 ' This is where I am stumped

我想做的是找出两个日期之间有多少个月。任何帮助，将不胜感激。

Answer 1

您可以使用以下方法：

Public Shared Function MonthDifference(ByVal first As DateTime, ByVal second As DateTime) As Integer
    Return Math.Abs((first.Month - second.Month) + 12 * (first.Year - second.Year))
End Function

像这样：

Dim Date1 As New DateTime(2010,5,6)
Dim Date2 As New DateTime(2009,10,12)
Dim NumOfMonths = MonthDifference(Date1, Date2)
