实现Button的动态响应

按下不同的Button实现不同的逻辑

但用同样的代码：

 using System.Reflection;

 namespace valuableBook
 {
     /// <summary>
     /// Interaction logic for Item.xaml
     /// </summary>
     public partial class Item : Window
     {
         public Item()
         {
             InitializeComponent();
         }

         private void Button_Click(object sender, RoutedEventArgs e)
         {
             Button cmd = e.OriginalSource as Button;
             Type type = this.GetType();
             Assembly assembly = type.Assembly;
             Window win = (Window)assembly.CreateInstance(type.Namespace + "." + cmd.Tag);
             win.ShowDialog();

         }
     }
 }

前台的Button

    <StackPanel Margin="" Button.Click="Button_Click">
             <Button Content="MainWindow" Tag="MainWindow"></Button>
         </StackPanel>

Msdn上的例子：

 using System;
 using System.Reflection;
 using Contoso.Libraries;

 namespace Contoso.Libraries
 {
    public class Person
    {
       private string _name;

       public Person()
       { }

       public Person(string name)
       {
          this._name = name;
       }

       public string Name
       { get { return this._name; }
         set { this._name = value; } }

       public override string ToString()
       {
          return this._name;
       }
    }
 }

 public class Example
 {
    public static void Main()
    {
       Assembly assem = typeof(Person).Assembly;
       Person p = (Person) assem.CreateInstance("Contoso.Libraries.Person");
       if (! (p == null)) {
          p.Name = "John";
          Console.WriteLine("Instantiated a {0} object whose value is '{1}'",
                            p.GetType().Name, p);
       }
       else {
          Console.WriteLine("Unable to instantiate a Person object.");
       }
    }
 }
 // The example displays the following output:
 //        Instantiated a Person object whose value is 'John'
