在现实的软件中，经常可以看到一些向导（Wizard）的存在，如何给自己的应用程序实现一个向导呢？
下面给出一个使用面向对象的思想设计出来的应用程序向导框架，虽然很简单，但希望能给人帮助。
其中有三个比较关键的类，一个是向导窗体要收集的信息封装成的类Information，一个是所有向导窗体都要继承的窗体基类frmBase，还有一个就是最关键的类，向导控制类WizardController。
有了基类frmBase，设计一个子类窗体非常简单，只需从frmBase类中派生一个新窗体，设计完用户界面之后重写其UpdateInfo()方法即可。
所有代码（VS2003版）如下，通俗易懂，不再做说明：
Information类：
using System;
namespace Wizard
{
/// <summary>
/// Information 的摘要说明。
/// </summary>
public class Information
{
public Information()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
//姓名
public string Name = "";
//性别
public bool IsMale = true;
//学历
public string EduBackground = "";
//编程语言
public string ProgrameLanguage = "";
}
}
frmBase类：
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
namespace Wizard
{
/// <summary>
/// frmBase 的摘要说明。
/// </summary>
public class frmBase : System.Windows.Forms.Form
{
private System.Windows.Forms.Panel panel1;
private System.Windows.Forms.Button btnGoPrev;
private System.Windows.Forms.Button btnGoNext;
private System.Windows.Forms.Button btnOver;
private System.Windows.Forms.Button btnCancel;
private System.Windows.Forms.Button btnHelp;
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.Container components = null;
public frmBase()
{
//
// Windows 窗体设计器支持所必需的
//
InitializeComponent();
//
// TODO: 在 InitializeComponent 调用后添加任何构造函数代码
//
}
/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
