Prism框架（二）——Prism应用程序初始化

Bootstrapper主要用来初始化Prism应用程序，其处理流程如图：

在Prism应用中，Bootstrapper的开发过程如下：
override基类的Bootstrapper
Unity基类提供了UnityBootstrapper和MefBootstrapper，可以根据实际的应用选用不同的Bootstrapper。
[csharp]
class DirectorBootstrapper : UnityBootstrapper
    {
        protected override System.Windows.DependencyObject CreateShell()
        {
            return Container.Resolve<Shell>();
        }

        protected override void InitializeShell()
        {
            Application.Current.MainWindow = (Window)Shell;
            Application.Current.MainWindow.Show();
        }
    }
在App类中调用Bootstrapper的Run函数
[csharp]
public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            DirectorBootstrapper bootstrapper = new DirectorBootstrapper();
            bootstrapper.Run();
        }
    }
配置ModuleCatalog
下面的代码使用plug in模式，将Module配置在Shell中。
[csharp]
protected override IModuleCatalog CreateModuleCatalog()
        {
            ModuleCatalog catalog = new ConfigurationModuleCatalog();
            return catalog;
        }

[html]
<configSections>
    <section name="modules" type="Microsoft.Practices.Prism.Modularity.ModulesConfigurationSection, Microsoft.Practices.Prism"/>
</configSections>

<modules>
    <module assemblyFile="Modules.DeviceManager.dll"
            moduleType="Modules.DeviceManager.DeviceManagerModule, Modules.DeviceManager"
            moduleName="DeviceManagerModule"/>
</modules>
实现模块接口
[csharp]
public class DeviceManagerModule : IModule
    {
        private IUnityContainer unityContainer;
        private IRegionManager regionManager;

        public DeviceManagerModule(IUnityContainer container, IRegionManager regionManager)
        {
            this.unityContainer = container;
            this.regionManager = regionManager;
        }

        #region IModule Members

        /// <summary>
        /// IModule inte易做图ce method called on module loading.
        /// </summary>
        public void Initialize()
        {
            this.regionManager.RegisterViewWithRegion(RegionNames.MainRegion,
                () => this.unityContainer.Resolve<DeviceView>("DeviceView"));
        }

        #endregion
    }
