最近我对开发PRISM WPF应用程序产生了兴趣。现在,我正试图从构建模块项目(Wpf用户控制库)后创建的DLL中加载我的模块。在模块项目的构建过程中,我复制调试文件夹中的DLL(副本:xcopy/y"$(TargetPath)"$(SolutionDir)FooBar\$(OutDir)modules\")。接下来,我配置引导程序,我想有是我丢失了它。
我将在下面附上我的代码。
引导程序
public class Bootstrapper : UnityBootstrapper
{
protected override DependencyObject CreateShell()
{
var shell = ServiceLocator.Current.GetInstance<Shell>();
return shell;
}
protected override void InitializeShell()
{
base.InitializeShell();
App.Current.MainWindow = (Window)this.Shell;
App.Current.MainWindow.Show();
}
protected override IModuleCatalog CreateModuleCatalog()
{
return base.CreateModuleCatalog();
}
protected override void ConfigureModuleCatalog()
{
var moduleCatalog = new DirectoryModuleCatalog();
moduleCatalog.ModulePath = Environment.CurrentDirectory + @"Modules";
ModuleCatalog = moduleCatalog;
}
protected override void InitializeModules()
{
base.InitializeModules();
}
protected override ILoggerFacade CreateLogger()
{
return base.CreateLogger();
}
}
Shell.xaml.cs
protected readonly IModuleCatalog _moduleCatalog;
public Shell(IModuleCatalog moduleCatalog)
{
this._moduleCatalog = moduleCatalog;
InitializeComponent();
}
App.xaml.cs
public partial class App : Application
{
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
var bootstrapper = new Bootstrapper();
bootstrapper.Run();
}
ViewModelBase
public abstract class ViewModelBase : INotifyPropertyChanging, INotifyPropertyChanged,IModule
{
//Implementation INotify etc..
public void Initialize()
{
}
}
所以我想知道为什么我的ModuleCatalog.Modules总是0。有人能帮我吗?
您的模块目录为空吗?或者不包含模块?检查Environment.CurrentDirectory+@"\Modules";返回正确的路径,并且所有DLL都在中。你真的需要从目录加载它们吗?你不知道会加载哪些模块吗?
我通常这样做:
public partial class Bootstrapper: UnityBootstrapper
{
protected override void ConfigureContainer()
{
base.ConfigureContainer();
}
protected override IModuleCatalog CreateModuleCatalog()
{
// Create the module catalog from a XAML file.
return Microsoft.Practices.Prism.Modularity.ModuleCatalog.CreateFromXaml(new Uri("/Shell;component/ModuleCatalog.xaml", UriKind.Relative));
}
protected override DependencyObject CreateShell()
{
// Use the container to create an instance of the shell.
ShellView view = Container.TryResolve<ShellView>();
// Display the shell's root visual.
//view.ShowActivated = false;
view.Show();
return view;
}
}
和我的模块目录
<prism:ModuleCatalog xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
xmlns:prism="clr-namespace:Microsoft.Practices.Prism.Modularity;assembly=Microsoft.Practices.Prism">

<sys:String>Tools</sys:String>
<sys:String>DrawingModule</sys:String>
</prism:ModuleInfo.DependsOn>
</prism:ModuleInfo>
并且所有模块都具有buildAction:copy"$(TargetPath)"$(SolutionDir)Shell\$(OutDir)"
