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="5" 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'
