操作說明:使用 DateTimePicker 控制項顯示時間
如果您希望應用程式可讓使用者選取日期和時間,並在指定的格式中顯示該日期和時間,請使用 DateTimePicker 控制項。 下列程序示範如何使用 DateTimePicker 控制項來顯示時間。
使用 DateTimePicker 控制項顯示時間
-
timePicker.Format = DateTimePickerFormat.Time;
timePicker.Format = DateTimePickerFormat.Time
將 DateTimePicker 的 ShowUpDown 屬性設定為
true
。timePicker.ShowUpDown = true;
timePicker.ShowUpDown = True
範例
下列程式碼範例示範如何建立 DateTimePicker,可讓使用者僅能選擇一個時間。
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
