推荐答案

你是在河边买水：Win Forms让你想要的东西变得非常简单：



1.在表单上放置一个DateTimePicker：'TimePicker24



设置DateTimePicker的这些属性：



格式：自定义

CustomFormat：HH：mm：ss tt

ShowTextBox：False

ShowUpDown：True

选中：错误



2.在表格上放置一个TextBox：'TimeTextBox



3.创建一个DateTimePicker的ValueChanged EventHandler：

You are "buying water by the river:" Win Forms makes what you want here very easy:

1. put a DateTimePicker on your Form: 'TimePicker24

Set these Properties of the DateTimePicker:

Format: Custom
CustomFormat: HH: mm: ss tt
ShowTextBox: False
ShowUpDown: True
Checked: False

2. put a TextBox on your Form: 'TimeTextBox

3. create a ValueChanged EventHandler for the DateTimePicker:

private void TimePicker24_ValueChanged(object sender, EventArgs e)
{
    TimeTextBox.Text = TimePicker24.Text;
}

您现在拥有一个功能齐全的24小时式时间选择器。当然，您可以根据需要设置其初始属性。



我建议您将当前时间值保留在DateTimePicker中...作为DateTime值...在变量中供进一步使用：

You now have a fully functional 24-hour style time picker. Of course, you can set-up its initial properties as you wish.

I suggest you keep the current time value selected in the DateTimePicker ... as a DateTime value ... in a variable for further use:

private DateTime CurrentTime;

private void TimePicker24_ValueChanged(object sender, EventArgs e)
{
    CurrentTime = TimePicker24.Value;
    TimeTextBox.Text = TimePicker24.Text;
}

你需要处理事件 NumericUpDown.ValueChanged ：

http://msdn.microsoft.com/en -us / library / system.windows.forms.numericupdown.valuechanged％28v = vs.110％29.aspx [ ^ ]。



在此事件的处理程序中，您可以读取 NumericUpDown 控件的当前值并更新属性 TextBox.Text 相应的文本框。

You need to handle the event NumericUpDown.ValueChanged:
http://msdn.microsoft.com/en-us/library/system.windows.forms.numericupdown.valuechanged%28v=vs.110%29.aspx[^].

In the handler of this event, you can read the current value of your NumericUpDown control and update the property TextBox.Text of your text box accordingly.
