patterns & practices Developer Center 发布了 Unity Application Block 1.2 for Silverlight - December 2008 依赖注入容器。用其来做MVP模式的silverlight会非常的方便，在正式开始MVP模型的学习前先简单的做了一个视图模型ViewModel的演练。
这里是我的代码：
ChristmasModel.cs
using System;
using System.ComponentModel;
namespace ChristmasViewModel
{
public class ChristmasModel : INotifyPropertyChanged
{
private bool _isShow1 = true;
private bool _isShow2 = true;
private bool _isShow3 = true;
private bool _isShow4 = true;
private bool _isShow5 = true;
private bool _isShow6 = true;
private bool _isShow7 = true;
private bool _isShow8 = true;
private bool _isShow9 = true;
private bool _isShow10 = true;
public bool IsShow1
{
get { return this._isShow1; }
set {
if (this._isShow1 != value) {
this._isShow1 = value;
this.RaisePropertyChanged("IsShow1");
}
}
}
public bool IsShow2
{
get { return this._isShow2; }
set
{
if (this._isShow2 != value)
{
this._isShow2 = value;
this.RaisePropertyChanged("IsShow2");
}
}
}
public bool IsShow3
{
get { return this._isShow3; }
set
{
if (this._isShow3 != value)
{
this._isShow3 = value;
this.RaisePropertyChanged("IsShow3");
}
}
}
public bool IsShow4
{

set
{

{
this._isShow4 = value;
this.RaisePropertyChanged("IsShow4");
}
}
}
public bool IsShow5
{
get { return this._isShow5; }
set
{
if (this._isShow5 != value)
{
this._isShow5 = value;
this.RaisePropertyChanged("IsShow5");
}
}
}
public bool IsShow6

set
{

{
this._isShow6 = value;
this.RaisePropertyChanged("IsShow6");
}
}
}
public bool IsShow7
{
get { return this._isShow7; }
set
{
if (this._isShow7 != value)
{
this._isShow7 = value;
this.RaisePropertyChanged("IsShow7");
}
}
}
public bool IsShow8
{
get { return this._isShow8; }
set
{
if (this._isShow8 != value)
{
this._isShow8 = value;
this.RaisePropertyChanged("IsShow8");
}
}
}
public bool IsShow9
{

set
{

this._isShow9 = value;
this.RaisePropertyChanged("IsShow9");
}
}
}
public bool IsShow10
{

set
{
if (this._isShow10 != value)
{
this._isShow10 = value;
this.RaisePropertyChanged("IsShow10");
}
}
}
#region INotifyPropertyChanged Members
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChanged(string propertyName) {
if (this.PropertyChanged != null) {
this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
#endregion
}
}
VisibilityConverter.cs
using System;
using System.Windows;
namespace ChristmasViewModel
{
public class VisibilityConverter : System.Windows.Data.IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

}
