在VB.NET中,可以使用DateDiff函数来计算两个日期之间的差异。DateDiff函数有几个参数,其中包括要计算的时间间隔单位以及起始日期和结束日期。

以下是DateDiff函数的语法:

DateDiff(interval As DateInterval, startDate As Date, endDate As Date)

以下是一个使用DateDiff函数的示例:

Dim startDate As Date = #1/1/2022#
Dim endDate As Date = #12/31/2022#
Dim yearDiff As Integer = DateDiff(DateInterval.Year, startDate, endDate)
Dim monthDiff As Integer = DateDiff(DateInterval.Month, startDate, endDate)
Dim dayDiff As Integer = DateDiff(DateInterval.Day, startDate, endDate)
Console.WriteLine("Years: " & yearDiff)
Console.WriteLine("Months: " & monthDiff)
Console.WriteLine("Days: " & dayDiff)

输出:

Years: 1
Months: 11
Days: 364

这个示例计算了从1/1/202212/31/2022之间的年份、月份和天数差异。
