桌面时钟

一个桌面时钟的小demo分享给大家，前几天重装系统，后来想美化一下写的，简约大气，美化win10必备，你值得拥有，代码贴出来，十几二十行代码搞定，如果权限不够请生成后右击以管理员身份运行

using Microsoft.Win32;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;

using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

using System.Windows.Forms.VisualStyles;

namespace 桌面时钟
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        //定义一个数组以显示星期
        private string[] weeks = { "", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };
        private void Form1_Load(object sender, EventArgs e)
        {
            #region 开机自启
            string path = Application.ExecutablePath;//取到当前应用程序的路径
            RegistryKey rk = Registry.LocalMachine;//得到注册表
            RegistryKey rk2 = rk.CreateSubKey(@"Software\Microsoft\Windows\CurrentVersion\Run");
            rk2.SetValue("DesktopClock", path);//为注册表设置新值 
            //Console.WriteLine(rk2.GetValue("DesktopClock").ToString());
            rk2.Close();
            rk.Close(); 
            #endregion
            //窗口透明化
            this.TransparencyKey = Color.White;
            this.BackColor = TransparencyKey;
            //获取当前屏幕的长和宽
            int screenX = Screen.PrimaryScreen.Bounds.Width;
            int screenY = Screen.PrimaryScreen.Bounds.Height;
            //让窗体居中显示
            int startPositionX = screenX / 2 - 325;
            int startPositionY = screenY / 2 - 240;
            this.Location = new System.Drawing.Point(startPositionX, startPositionY);
        }
        //为timer委托事件
        private void timer1_Tick(object sender, EventArgs e)
        {
            string time = DateTime.Now.ToString("t");//取到当前时分
            string date = DateTime.Now.ToString("yy/MM/dd");//取到当前年月日
            string week = weeks[(int)DateTime.Now.DayOfWeek];//得到星期字符串
            label1.Text = time + "\r\n" + date + "\r\n" + week;//连接字符串用label显示
        }
    } 
}

效果如下
