vb.net时间间隔的简单介绍

vb.net计算两个日期之间相差多少天

function getTime2Time($time1, $time2)

{

var time1 = arguments[0], time2 = arguments[1];

time1 = Date.parse(time1)/1000;

time2 = Date.parse(time2)/1000;

var time_ = time1 - time2;

return (time_/(3600*24));

}

document.write(getTime2Time('2016-08-02', '2016-07-02'));

vb.net时间间隔的计算

Public Class Form1

Private Past As Date

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Past = Now

IO.File.AppendAllText("test.txt", Past.ToString, System.Text.Encoding.Default)

End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim Now1 As Date = CDate(IO.File.ReadAllText("test.txt", System.Text.Encoding.Default))

Dim Now2 As Date = Now

MsgBox("从" Now1.ToString "到" Now2.ToString "经过了" CStr(CDate((Now2 - Now1).ToString)))

End Sub

实际情况修改下。

End Class

VB.Net 如何计算两个日期间隔有多少个双月，多少个半年？

如果DateDiff(月，开始日期，结束日期)=6

在检查开始日期的月份是不是1或者7，如果是在检查结束日期的月份是不是6或者12，如果都满足 就是半年

如果DateDiff(月，开始日期，结束日期)=2并且 开始日期的月份不能被2整除 就是双月
