屏保程序
样子如下:(动态的字会随时间改变并移动.中央偏上有时间显示)
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;namespace screensaver{public partial class Form1 : Form{public Form1(){InitializeComponent();}private void Form1_Load(object sender, EventArgs e){lblShowtime.Text = DateTime.Now.ToString();//lblShowtime显示现在的时间//让时间显示在中央偏上lblShowtime.Top = (this.Height-lblShowtime.Height) / 2-lblShowtime.Height;lblShowtime.Left = (this.Width - lblShowtime.Width) / 2;}int moveX = 10;//作为左右移动量的变量int moveY = 8;//作为上下移动量的变量int t= 1;//作为label文本变化的判断private void timer1_Tick(object sender, EventArgs e){Random rnd = new Random();this.label1.Left += moveX;//向右移动this.label1.Top += moveY;//向下移动if (this.Width < this.label1.Left + this.label1.Width || this.label1.Left < 0)//如果label标签到form窗体左右边界就反向,且t值改变{moveX = -moveX;t = -t;}if ( this.Height<this.label1.Top + this.label1.Height || this.label1.Top < 0)//如果label标签到form窗体上下边界就反向,且t值改变{moveY = -moveY;t = -t;}//label到边界,就改变文本if (t == 1){ this.label1.Text = \"Windows2020\"; }else{ this.label1.Text = \"张悦张悦我爱你\"; }this.label1.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));//设置字体颜色随时间随机改变}private void Form1_MouseMove(object sender, System.Windows.Forms.MouseEventArgs e){// Application.Exit();//鼠标移动则程序退出}private void Form1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e){Application.Exit();//键盘按下则程序退出}private void timerShowtime_Tick(object sender, EventArgs e){lblShowtime.Text = DateTime.Now.ToString();//lblShowtime显示现在的时间,并每秒进行时间的更新(1000ms=1s)}}}/////////////////////////////////////////////////////////////////////////////////////////////步骤: ////////////BackColor背景设为黑色 ////////////WindowState窗口状态最大化Maximized ///////////FromBorderStyle窗口边框设为无边框None ///////////标签设为白色 //////////标签设timeTicket事件,让它随时间移动 /////////设置鼠标移动和键盘按下则退出(Exit) /////////将生成的exe文件复制到C:\\Windows\\System32里,并重命名为xxx.scr文件,并安装 ///////////////////////////////////////////////////////////////////////////////////////////
