如何：通过使用 DateTimePicker 控件显示时间 - Windows Forms .NET Framework

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 DateTimePicker 的 ShowUpDown 属性设置为 true。
timePicker.ShowUpDown = true;
timePicker.ShowUpDown = True
下面的代码示例演示如何创建一个 DateTimePicker，使用户能够仅选择时间。
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
    <STAThread()> _
    Shared Sub Main()
        Application.EnableVisualStyles()
        Application.Run(New Form1())
    End Sub
End Class
