基于c#的时钟

代码说明：

资源描述本源程序是基于C#的时钟设计，能为初学者提供参考价值，为初学者提供基本的编写代码思路， namespace Clock { public partial class MainForm : Form { private PointF center; private float r; private Pen hourPen; private Pen minutePen; private Pen secondPen; private Thread timeThread; public MainForm() { InitializeComponent(); ShowInTaskbar = false;//不在任务栏中显示 SetStyle(ControlStyles.DoubleBuffer, true); SetStyle(ControlStyles.UserPaint,true); SetStyle(ControlStyles.AllPaintingInWmPaint,true); center = new PointF(ClientSize.Width/ 2.0f, ClientSize.Height/ 2.0f); r = Math.Min(ClientSize.Width / 2.0f, ClientSize.Height / 2.0f); hourPen = new Pen(Color.Black, 2.5f); minutePen = new Pen(Color.Black, 1.5f); secondPen = new Pen(Color.Black, 0.5f); timeThread=new Thread(new ThreadStart(DrawTime)); timeThread.Start(); } protected override void OnPaint(PaintEventArgs e) { Graphics g = e.Graphics; g.Clear(BackColor); //g.SmoothingMode =
