操作描述：

在程序运行后，点击“Load”按钮，页面会加载PageOne,点击PageOne页面中的“Next”按钮即可进入PageTwo页面，

点击PageTwo页面中的“Next”即可进入PageThree页面，点击Back可返回Page1页面

第一步：新建工程并使用NuGet安装MvvmLight

第二步：添加Views文件夹并添加相应的ViewModel

本文主要描述如何使用MvvmLight实现简单的导航效果，所以页面基本上都是大同小异比较简单ViewModel也比较简单，所以这里只PageOne.xaml以及PageOneViewModel.cs

PageOne.xaml代码:

<Page x:Class="MvvmLightSample.Views.PageOne"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
      xmlns:local="clr-namespace:MvvmLightSample.Views"
      mc:Ignorable="d" 
      Title="PageOne">
    <Page.DataContext>
        <Binding Path="PageOne" Source="{StaticResource Locator}"></Binding>
    </Page.DataContext>
    <Grid Background="Orange">
        <TextBlock Text="1" Foreground="White" FontSize="30"></TextBlock>
        <StackPanel Orientation="Vertical" HorizontalAlignment="Center" VerticalAlignment="Center">
            <TextBlock Text="{Binding Title}" FontSize="18" Foreground="White"></TextBlock>
            <Button Width="80" Height="20" Content="Click me!!!" Margin="0,20,0,0" Command="{Binding ChangeCommand}"></Button>
        </StackPanel>
        <Button Command="{Binding GoToNextCommand}"  Content="Next" Width="60" Height="30" VerticalAlignment="Bottom" HorizontalAlignment="Right" Margin="0,0,10,10"></Button>
    </Grid>
</Page>

PageOneViewModel.cs代码:

  public class PageOneViewModel : ViewModelBase
        private INavigationService _navigationService;
        public ICommand GoBackCommand { get; set; }
        public ICommand GoToNextCommand { get; set; }
        public ICommand ChangeCommand { get; set;}
        private string _title;
        public string Title
            get { return _title; }
                Set(()=>Title,ref _title,value);
        public PageOneViewModel(INavigationService navigationService)
            _navigationService = navigationService;
            Title = "Please Click me!";
            GoBackCommand = new RelayCommand(GoBack);
            GoToNextCommand = new RelayCommand(GotoNext);
            ChangeCommand = new RelayCommand(ChangeTitle);
        private void ChangeTitle()
            Title = "Hello MvvmLight!!!";
        private void GoBack()
            _navigationService.GoBack();
        private void GotoNext()
            var navigationService = ServiceLocator.Current.GetInstance<INavigationService>();
            navigationService.NavigateTo("PageTwo2");
第三步:修改ViewModelLocator.cs
 public class ViewModelLocator
        /// <summary>
        /// Initializes a new instance of the ViewModelLocator class.
        /// </summary>
        public ViewModelLocator()
            ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);
            SimpleIoc.Default.Register<MainViewModel>();
            SimpleIoc.Default.Register<PageOneViewModel>();
            SimpleIoc.Default.Register<PageTwoViewModel>();
            SimpleIoc.Default.Register<PageThreeViewModel>();
            SimpleIoc.Default.Register<PageFourViewModel>();
            var navigationService = this.CreateNavigationService();
            SimpleIoc.Default.Register<INavigationService>(() => navigationService);
        private INavigationService CreateNavigationService()
            var nav = new NavigationService();
            var navigationService = new NavigationService();
            navigationService.Configure("PageTwo1", new Uri("/MvvmLightSample;component/Views/PageOne.xaml", UriKind.Relative));
            navigationService.Configure("PageTwo2", new Uri("/MvvmLightSample;component/Views/PageTwo.xaml", UriKind.Relative));
            navigationService.Configure("PageTwo3", new Uri("/MvvmLightSample;component/Views/PageThree.xaml", UriKind.Relative));
            navigationService.Configure("PageTwo4", new Uri("/MvvmLightSample;component/Views/PageFour.xaml", UriKind.Relative));
            return navigationService;
        public MainViewModel Main
                return ServiceLocator.Current.GetInstance<MainViewModel>();
        public PageOneViewModel PageOne
                return ServiceLocator.Current.GetInstance<PageOneViewModel>();
        public PageTwoViewModel PageTwo
                return ServiceLocator.Current.GetInstance<PageTwoViewModel>();
        public PageThreeViewModel PageThree
                return ServiceLocator.Current.GetInstance<PageThreeViewModel>();
        public PageFourViewModel PageFour
                return ServiceLocator.Current.GetInstance<PageFourViewModel>();
        public static void Cleanup()
NavigationService.cs代码:
 public class NavigationService : ViewModelBase,INavigationService 
        private readonly Dictionary<string, Uri> _pagesByKey;
        private readonly List<string> _historic;
        private string _currentPageKey;
        #region Properties
        public string CurrentPageKey
                return _currentPageKey;
            private set
               Set(()=>CurrentPageKey,ref _currentPageKey,value);
        public object Parameter { get; private set; }
        #endregion
        #region Ctors and Methods
        public NavigationService()
            _pagesByKey = new Dictionary<string, Uri>();
            _historic = new List<string>();
        public void GoBack()
            if (_historic.Count > 1)
                _historic.RemoveAt(_historic.Count - 1);
                NavigateTo(_historic.Last(), "Back");
        public void NavigateTo(string pageKey)
            NavigateTo(pageKey, "Next");
        public virtual void NavigateTo(string pageKey, object parameter)
            lock (_pagesByKey)
                if (!_pagesByKey.ContainsKey(pageKey))
                    throw new ArgumentException(string.Format("No such page: {0} ", pageKey), "pageKey");
                var frame = GetDescendantFromName(Application.Current.MainWindow, "MainFrame") as Frame;
                if (frame != null)
                    frame.Source = _pagesByKey[pageKey];
                Parameter = parameter;
                if (parameter.ToString().Equals("Next"))
                    _historic.Add(pageKey);
                CurrentPageKey = pageKey;
        public void Configure(string key, Uri pageType)
            lock (_pagesByKey)
                if (_pagesByKey.ContainsKey(key))
                    _pagesByKey[key] = pageType;
                    _pagesByKey.Add(key, pageType);
        private static FrameworkElement GetDescendantFromName(DependencyObject parent, string name)
            var count = VisualTreeHelper.GetChildrenCount(parent);
            if (count < 1)
                return null;
            for (var i = 0; i < count; i++)
                var frameworkElement = VisualTreeHelper.GetChild(parent, i) as FrameworkElement;
                if (frameworkElement != null)
                    if (frameworkElement.Name == name)
                        return frameworkElement;
                    frameworkElement = GetDescendantFromName(frameworkElement, name);
                    if (frameworkElement != null)
                        return frameworkElement;
            return null;
        #endregion

原文:silverlight，WPF动画终极攻略之番外  3D切换导航篇（Blend 4开发）
这篇介绍的是3D导航，点击图标，页面360°翻转的效果！有什么不足的欢迎大家指出来。
1.新建一个usercontrol，命名为menu.
2.按照下图设置一下属性。
