前言
C#實踐開發_Winform 系列第三篇：飄動窗體，掌握l定時器控件使用。
一、結果呈現
1. 界面設計
窗體界面設計：四個Timer定時器控件（設定Interval值為100，即每隔0.1秒觸發事件timer_Tick（）），四個label标簽（顯示功能）。
2. 運作結果呈現
二、源碼
1.Form.cs
代碼如下（示例）：
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 test_4_2
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
Point p = new Point(0, 240); //設定窗體初始位置
this.DesktopLocation = p;
timer1.Enabled = true;
}
private void timer1_Trick(object sender, System.EventArgs e)
{
Point p = new Point(this.DesktopLocation.X + 1, this.DesktopLocation.Y + 1);
this.DesktopLocation = p;
if (p.X == 470 && p.Y == 710)
{
timer1.Enabled = false;
timer2.Enabled = true;
timer3.Enabled = false;
timer4.Enabled = false;
label1.Visible = false;
label2.Visible = true;
label3.Visible = false;
label4.Visible = false;
}
}
private void timer2_Trick(object sender, System.EventArgs e)
{
Point p = new Point(this.DesktopLocation.X + 1, this.DesktopLocation.Y - 1);
this.DesktopLocation = p;
if (p.X == 940 && p.Y == 240)
{
timer1.Enabled = false;
timer2.Enabled = false;
timer3.Enabled = true;
timer4.Enabled = false;
label1.Visible = false;
label2.Visible = false;
label3.Visible = true;
label4.Visible = false;
}
}
private void timer3_Trick(object sender, System.EventArgs e)
{
Point p = new Point(this.DesktopLocation.X -1, this.DesktopLocation.Y - 1);
this.DesktopLocation = p;
if (p.X == 470 && p.Y == -230)
{
timer1.Enabled = false;
timer2.Enabled = false;
timer3.Enabled = false;
timer4.Enabled = true;
label1.Visible = false;
label2.Visible = false;
label3.Visible = false;
label4.Visible = true;
}
}
private void timer4_Trick(object sender, System.EventArgs e)
{
Point p = new Point(this.DesktopLocation.X - 1, this.DesktopLocation.Y + 1);
this.DesktopLocation = p;
if (p.X == 0 && p.Y == 240)
{
timer1.Enabled = true;
timer2.Enabled = false;
timer3.Enabled = false;
timer4.Enabled = false;
label1.Visible = true;
label2.Visible = false;
label3.Visible = false;
label4.Visible = false;
}
}
}
}
2.Form.Designer.cs
代碼如下（示例）：
namespace test_4_2
{
partial class Form2
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
#region Windows Form Designer generated code

/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>

private System.Windows.Forms.Timer timer3;
private System.Windows.Forms.Timer timer4;

}
三、總結
設計思路： 首先加載窗體的時候給窗體設定一個顯示的初始位置，再利用Timer控件，實作窗體飄動效果。
