WPF Prism 7.0+ IModule（模块化)

源码下载：PrismCore.zip

安装程序包Prism.DryIoc

设置模块

regionManager.Regions["LoginRegion"].RequestNavigate(obj); 

 无参数导航

regionManager.RequestNavigate("LoginRegion", "LoginControl");

 带参数导航

NavigationParameters pairs = new NavigationParameters();
pairs.Add("参数名", "参数值");
regionManager.Regions["LoginRegion"].RequestNavigate(obj, pairs);

 

 

创建模块：

 LoginProfile.cs

public class LoginProfile : IModule
{
    public void OnInitialized(IContainerProvider containerProvider)
    {
    }

    public void RegisterTypes(IContainerRegistry containerRegistry)
    {
        containerRegistry.RegisterForNavigation<Views.LoginControl, ViewModels.LoginViewModel>();
    }
}

 LoginViewModel.cs

namespace LoginModule.ViewModels
{
    public class LoginViewModel : BindableBase
    {
        public DelegateCommand LoginCommand { get; private set; }
        public LoginViewModel()
        {
            LoginCommand = new DelegateCommand(OnLogin);
        }

        private void OnLogin()
        {
            string username = UserName;
            string password = Password;
        }
        /// <summary>
        /// 账号
        /// </summary>
        private string _username = string.Empty;
        public string UserName
        {
            get { return _username; }
            //数据同步方法：RaisePropertyChanged();
            set { _username = value; RaisePropertyChanged(); }
        }
        /// <summary>
        /// 密码
        /// </summary>
        private string _password = string.Empty;
        public string Password
        {
            get { return _password; }
            //数据同步方法：RaisePropertyChanged();
            set { _password = value; RaisePropertyChanged(); }
        }
    }
}

 LoginControl.xaml

<UserControl x:Class="LoginModule.Views.LoginControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:local="clr-namespace:LoginModule.Views"
             xmlns:prism="http://prismlibrary.com/"
             prism:ViewModelLocator.AutoWireViewModel="True"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid Height="100" Background="Aquamarine">
        <StackPanel>
            <DockPanel>
                <Label Content="账号：" Width="120" HorizontalContentAlignment="Right"/>
                <TextBox Text="{Binding UserName}"/>
            </DockPanel>
            <DockPanel>
                <Label Content="密码：" Width="120" HorizontalContentAlignment="Right"/>
                <TextBox Text="{Binding Password}"/>
            </DockPanel>
            <DockPanel>
                <Label Content="" Width="120"/>
                <Button Content="登录" Width="120" HorizontalAlignment="Left" Command="{Binding LoginCommand}"/>
            </DockPanel>
        </StackPanel>
    </Grid>
</UserControl>

 

主项目注册模块

public partial class App : PrismApplication
{
    // Window窗体， StartupUri可以启动一个窗体
    // CreateShell()主要负责启动一个主页面
    protected override Window CreateShell()
    {
        // 启动一个窗体MainWindow
        return Container.Resolve<Views.MainWindow>();
    }
    //通过IOC容器注册IApplicationCommands为单例
    protected override void RegisterTypes(IContainerRegistry containerRegistry)
    {
            
    }

    //注册子窗体模块
    protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog)
    {
        //添加模块A
        moduleCatalog.AddModule<LoginModule.Profiles.LoginProfile>();
        base.ConfigureModuleCatalog(moduleCatalog);
    }
    //方式2 如果不用 引用库的方式  可以重写此方法 把dll 放在同一文件夹
    /*protected override IModuleCatalog CreateModuleCatalog()
    {
        //此 模块注入方式 是把所有相关的dll放在统一文件夹 Modules下，会检索所有实现了IModule接口的类，注册到容器
        return new DirectoryModuleCatalog { ModulePath = @".\Modules" };
    }*/
}

 主项目切换模块：

public class MainWindowViewModel : BindableBase
{
    private readonly IRegionManager regionManager;
    public DelegateCommand<string> OpenModuleViewCommand { get; private set; }
    public MainWindowViewModel(IRegionManager _regionManager)
    {
        OpenModuleViewCommand = new DelegateCommand<string>(OpenModuleView);
        regionManager = _regionManager;
    }

    private void OpenModuleView(string obj)
    {
        regionManager.Regions["LoginContentRegion"].RequestNavigate(obj);
    }
}

 主项目使用模块：

<ContentControl prism:RegionManager.RegionName="LoginContentRegion"/>
