DateTime PIcker显示小时和分钟 [英] DateTime PIcker to Display hour and min

问题描述

嗨

我正在使用日期时间选择器以hr和MIN
显示时间
我希望datetime选择器以这样的方式显示小时和时间:小时应增加1，最小应增加15(例如:0,15,30,45)

到目前为止，我知道了

Hi

I am Using Date time picker to display the time in hr AND MIN

I want the datetime picker to show the hour and time in such a way that hour should increment by 1 and min should increment by 15(eg: 0,15,30,45)

This is so far i got

DTPendtime.CustomFormat = "HH:mm"//where DTPendtime is datetime picker
        DTPendtime.Format = DateTimePickerFormat.Custom
        DTPendtime.ShowUpDown = True

Private Sub DTPendtime_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DTPendtime.ValueChanged
      txtendtime.Text = DTPendtime.Text
  End Sub

推荐答案

这是VB版本:

This the VB version:

Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
    Dim d As DateTime = DateTimePicker1.Value
    Dim i As Integer = d.Minute Mod 15
    If (i > 0) Then
        DateTimePicker1.Value = DateTimePicker1.Value.AddMinutes(15 - i).AddSeconds(-d.Second)
    End If
End Sub

尝试如下操作:

Try something like this:

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{
    var diff = dateTimePicker1.Value.TimeOfDay.Minutes % 15;
    if (diff != 0)
    {
        dateTimePicker1.Value = dateTimePicker1.Value.AddMinutes(15 - diff);
    }
}
