如果希望应用程序允许用户选择日期和时间，并按指定格式显示该日期和时间，请使用 DateTimePicker 该控件。 以下过程演示如何使用 DateTimePicker 控件显示时间。
使用 DateTimePicker 控件来显示时间
将 Format 属性设置为 Time
timePicker.Format = DateTimePickerFormat.Time;
timePicker.Format = DateTimePickerFormat.Time
将 ShowUpDown 属性 DateTimePicker 设置为 true.
timePicker.ShowUpDown = true;
timePicker.ShowUpDown = True
示例：
下面的代码示例演示如何创建一个 DateTimePicker 仅允许用户选择时间的代码示例。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace TimePickerApplication
{
public class Form1 : Form
{
public Form1()
{
InitializeTimePicker();
}
private DateTimePicker timePicker;
private void InitializeTimePicker()
{
timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Time;
timePicker.ShowUpDown = true;
timePicker.Location = new Point(10, 10);
timePicker.Width = 100;
Controls.Add(timePicker);
}
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.Run(new Form1());
}
}
}
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Drawing
Imports System.Text
Imports System.Windows.Forms
Public Class Form1
Inherits Form
Public Sub New()
InitializeTimePicker()
End Sub
Private timePicker As DateTimePicker
Private Sub InitializeTimePicker()
timePicker = New DateTimePicker()
timePicker.Format = DateTimePickerFormat.Time
timePicker.ShowUpDown = True
timePicker.Location = New Point(10, 10)
timePicker.Width = 100
Controls.Add(timePicker)
End Sub
Shared Sub Main()
Application.EnableVisualStyles()
Application.Run(New Form1())
End Sub
End Class
