WinForm实现状态栏跑马灯效果的方法示例

本文实例讲述了WinForm实现状态栏跑马灯效果的方法。分享给大家供大家参考，具体如下：

?

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace WindowsFormsApplication1

{

   public partial class Form1 : Form

   {

     public Form1()

     {

       InitializeComponent();

     }

     private Label label = new Label();

     public string text = "csdn baihe_591" ;

     private void Form1_Load( object sender, EventArgs e)

     {

       this .label.Location = new Point(149, 13);

       this .label.Size = new Size(134, 16);

       this .Controls.Add(label);

       this .label.Text = "" ;

       this .timer1.Enabled = true ;

       this .timer1.Interval = 500;

       p = new PointF( this .label.Size.Width, 0);

     }

     PointF p;

     Font f = new Font( "宋体" , 10);

     Color c = Color.White;

     string temp;

     private void timer1_Tick( object sender, EventArgs e)

     {

       Graphics g = this .label.CreateGraphics();

       SizeF s = new SizeF();

       s = g.MeasureString(text, f); //测量文字长度

       Brush brush = Brushes.Black;

       g.Clear(c); //清除背景

       if (temp != text) //文字改变时,重新显示

       {

         p = new PointF( this .label.Size.Width, 0);

         temp = text;

       }

       else

         p = new PointF(p.X - 10, 0); //每次偏移10

       if (p.X <= -s.Width)

         p = new PointF( this .label.Size.Width, 0);

       g.DrawString(text, f, brush, p);

     }

   }

}

希望本文所述对大家C#程序设计有所帮助。
