我希望在两个日期时间选择器中选择的两个日期之间的区别在于单独的文本框中的年,月和日.

我试过了:

txtyrs.text = datediff(datetimepicker1,datetimepicker2)

它不起作用.

在我的下面的代码中,如何设置到达日期和降级,以便我可以获得应付金额？我需要设置它们,因为我住在酒店的日子,所以我可以拿出一个总数.如果这有道理吗？我在Visual Basic中使用datetimepickers.

Public Class RentalForm
    'declare constants
    Const tax_rate_decimal As Decimal = 12.25D
    Const king_price_decimal As Decimal = 110.9D
    Const queen_price_decimal As Decimal = 105.9D
    Const double_price_decimal As Decimal = 95.9D

    'declare variables
    Private roomchargesumdecimal, taxamountsumdecimal, amountduesumdecimal As Decimal

    Private Sub exitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles exitButton.Click
        Close()
    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBoxnameofguest.TextChanged

    End Sub

    Private Sub calculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculateButton.Click …

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。
