Question

只是想问一下如何获得本月，上个月，今年和去年的日期时间选择器在vb.net 2012中是否有可能？例如，我在组合框中选择“本月”，然后将日期时间选择器值更改为今天的月份。这是我的代码结构..

Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
    'if "Today" was chosen
    If ComboBox1.SelectedIndex = 1 Then
        DateTimePicker1.Value = Today
        DateTimePicker2.Value = Today
        'if "This Month" was chosen
    ElseIf ComboBox1.SelectedIndex = 2 Then

    End If
End Sub

Answer 1

上个月

 DateTimePicker1.Value=Now.AddMonths(-1).ToString("dd/MM/yyyy")

去年获得

  DateTimePicker1.Value= Now.AddYears(-1).ToString("dd/MM/yyyy")

日期时间选择器条件或值
