本文实例为大家分享了C#实现动态数字时钟和日历的具体代码，供大家参考，具体内容如下

实现如下图所示的简易时钟和日历，要求显示公历日期、时间、星期、农历日期。

首先新建一个ChineseCanlendar类用于实现和农历相关的操作：

【ChineseCanlendar.cs】

/*

*/

using System;
using System.Linq;
using System.Globalization;

namespace Test2_1
{
static public class ChineseCanlendar
{
private static ChineseLunisolarCalendar ChineseCalendar = new ChineseLunisolarCalendar();
private static string[] tg = { "甲", "乙", "丙", "丁", "戊", "己", "庚", "辛", "壬", "癸" };
private static string[] dz = { "子", "丑", "寅", "卯", "辰", "巳", "午", "未", "申", "酉", "戌", "亥" };
private static string[] sx = { "鼠", "牛", "虎", "兔", "龙", "蛇", "马", "羊", "猴", "鸡", "狗", "猪" };
public static string GetLunisolarYear(int year)
{
if (year > 3)
{
int tgIndex = (year - 4) % 10;
int dzIndex = (year - 4) % 12;
return string.Concat(tg[tgIndex], dz[dzIndex], "[", sx[dzIndex], "]");
}
throw new ArgumentOutOfRangeException("年份无效!");
}
private static string[] months = { "正", "二", "三", "四", "五", "六", "七", "八", "九", "十", "十一", "十二(腊)" };
private static string[] days1 = { "初", "十", "廿", "三" };
private static string[] days = { "一", "二", "三", "四", "五", "六", "七", "八", "九", "十" };
public static string GetLunisolarMonth(int month)
{
if (month < 13 && month > 0)
{
return months[month - 1];
}
throw new ArgumentOutOfRangeException("月份无效!");
}
public static string GetLunisolarDay(int day)
{
if (day > 0 && day < 32)
{
if (day != 20 && day != 30)
{
return string.Concat(days1[(day - 1) / 10], days[(day - 1) % 10]);
}
else
{
return string.Concat(days[(day - 1) / 10], days1[1]);
}
}
throw new ArgumentOutOfRangeException("无效日期!");
}
public static string GetChineseDateTime(DateTime datetime)
{
int year = ChineseCalendar.GetYear(datetime);
int month = ChineseCalendar.GetMonth(datetime);
int day = ChineseCalendar.GetDayOfMonth(datetime);
int leapMonth = ChineseCalendar.GetLeapMonth(year);
bool isleap = false;
if (leapMonth > 0)
{
if (leapMonth == month)
{
isleap = true;
month--;
}
else if (month > leapMonth)
{
month--;
}
}
return string.Concat(GetLunisolarYear(year), "年", isleap ? "闰" : string.Empty, GetLunisolarMonth(month), "月", GetLunisolarDay(day));
}
}
}

【窗体设计】

从上到下设置三个标签，并添加背景颜色，为了使效果更佳，最好将窗口全部填满：

【MainForm.cs】

*/

using System;
using System.Linq;
using System.Windows.Forms;

namespace Test2_1
{
public partial class MainForm : Form
{
public MainForm()
{
InitializeComponent();
timer1.Start();
}
void Timer1Tick(object sender, EventArgs e)
{
label1.Text = DateTime.Now.ToString();
switch(DateTime.Now.DayOfWeek.ToString())
{
case "Monday":
label2.Text = "星期一"; break;
case "Tuesday":
label2.Text = "星期二"; break;
case "Wednesday":
label2.Text = "星期三"; break;
case "Thursday":
label2.Text = "星期四"; break;
case "Friday":
label2.Text = "星期五"; break;
case "Saturday":
label2.Text = "星期六"; break;
case "Sunday":
label2.Text = "星期日"; break;
}
string GCDT = ChineseCanlendar.GetChineseDateTime(DateTime.Now);
label3.Text = GCDT;
}
}
}

【Program.cs】

/*

*/

using System;
using System.Windows.Forms;

namespace Test2_1
{
internal sealed class Program
{
[STAThread]
private static void Main(string[] args)
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MainForm());
}
}
}
