通過上面的介紹，不難寫出窗體飄動的程序源代碼。如下：
using System ;
using System.Drawing ;
using System.Collections ;
using System.ComponentModel ;
using System.Windows.Forms ;
using System.Data ;
namespace floatingForm
{
public class Form1 : Form
{
private Timer timer1 ;
private Timer timer2 ;
private Label label1 ;
private Button button1 ;
private System.ComponentModel.IContainer components ;
public Form1 ( )
{
file://初始化窗體中的各個組件
InitializeComponent ( ) ;
}
file://清除在程序中使用過的資源
protected override void Dispose ( bool disposing )
{
if ( disposing )
{
if ( components != null )
{
components.Dispose ( ) ;
}
}
base.Dispose( disposing ) ;
}
private void InitializeComponent ( )
{
this.components = new System.ComponentModel.Container ( ) ;
this.timer1 = new Timer ( this.components ) ;
this.timer2 = new Timer ( this.components ) ;
this.label1 = new Label ( ) ;
this.button1 = new Button ( ) ;
this.SuspendLayout ( ) ;
this.timer1.Enabled = true ;
this.timer1.Interval = 10 ;
this.timer1.Tick += new System.EventHandler ( this.timer1_Tick ) ;
this.timer2.Enabled = false ;
this.timer2.Interval = 10 ;
this.timer2.Tick += new System.EventHandler ( this.timer2_Tick ) ;
this.button1.Font = new Font ( "宋體" , 10 ) ;
this.button1.Location = new Point ( 1 , 8 ) ;
this.button1.Name = "button1" ;
this.button1.Size = new Size ( 80 , 25 ) ;
this.button1.TabIndex = 0 ;
this.button1.Text = "停止飄動" ;
this.button1.Click += new System.EventHandler ( this.button1_Click ) ;
this.label1.Font = new Font ( "宋體" , 22F , FontStyle.Bold , GraphicsUnit.Point , ( ( System.Byte ) ( 0 ) ) ) ;
this.label1.Location = new Point ( 8 , 38 ) ;
this.label1.Name = "label1" ;
this.label1.Size = new Size ( 344 , 40 ) ;
this.label1.TabIndex = 1 ;
this.label1.Text = "用Visual C＃做的飄動的窗體！" ;
this.AutoScaleBaseSize = new Size ( 5 , 13 ) ;
this.ClIEntSize = new Size ( 352 , 70 ) ;
this.Controls.Add (this.label1 ) ;
this.Controls.Add (this.button1 ) ;
this.Name = "Form1" ;
this.Text = "用Visual C＃做的飄動的窗體！";
this.Load += new System.EventHandler ( this.Form1_Load ) ;
this.ResumeLayout ( false ) ;
}
static void Main ( )
{
Application.Run ( new Form1 ( ) ) ;
}
file://設定窗體起初飄動的位置
private void Form1_Load ( object sender , System.EventArgs e )
{
Point p = new Point ( 0 , 240 ) ;
this.DesktopLocation = p ;
}
file://當窗體左上角位置的橫坐標為550時，timer1停止，timer2啟動
private void timer1_Tick(object sender, System.EventArgs e)
{
file://窗體的左上角橫坐標隨著timer1不斷加一
Point p = new Point ( this.DesktopLocation.X + 1 , this.DesktopLocation.Y ) ;
this.DesktopLocation = p ;
if ( p.X == 550 )
{
timer1.Enabled = false ;
timer2.Enabled = true ;
}
}
file://當窗體左上角位置的橫坐標為-150時，timer2停止，timer1啟動
private void timer2_Tick(object sender, System.EventArgs e)
{ file://窗體的左上角橫坐標隨著timer2不斷減一
Point p = new Point ( this.DesktopLocation.X - 1 , this.DesktopLocation.Y ) ;
this.DesktopLocation = p ;
if ( p.X == - 150 )
{
timer1.Enabled = true ;
timer2.Enabled = false ;
}
}
file://停止所有的timer
private void button1_Click(object sender, System.EventArgs e)
{
timer1.Stop ( ) ;
timer2.Stop ( ) ;
}
}
}
四． 總結：
恰到好處的使用Timer組件往往會有出其不意的效果。由於本文的主要目的是介紹Timer組件的使用方法，程序功能還不是十分強大，感興趣的讀者，可以試著按照下面的思路進行修改，看看是否可以讓窗體上下飄動，讓窗體不定規則的飄動。當然如果你更有興趣，也可以把窗體的邊框和最大化、最小化等按鈕給隱去，放一個好看的圖片充滿整個窗體，再讓他飄動起來，這樣效果就更令人驚訝了。
