利用Prism框架搭建Mvvm模式WPF程序

吴旭华 · 2024-12-31 12:11:23

一、利用NuGet安装Prism框架

二、构建ViewModel基类，注册导航器，弹窗服务，事件聚合器，多语言，log4net日记
1、新建ViewModelBase基类，继承自BindableBase, INavigationAware, IRegionMemberLifetime, IConfirmNavigationRequest构建ViewModel的通用方法，其他页面的ViewModel类均继承该基类即可。

1 public abstract class ViewModelBase : BindableBase, INavigationAware, IRegionMemberLifetime, IConfirmNavigationRequest
2 {
3 /// <summary>
4 /// 导航器
5 /// </summary>
6 public IRegionManager Region;
7 /// <summary>
8 /// 弹窗服务
9 /// </summary>
10 public IDialogService Dialog;
11 /// <summary>
12 /// 事件聚合器
13 /// </summary>
14 public IEventAggregator Event;
15 /// <summary>
16 /// 日志
17 /// </summary>
18 public ILogger Logger;
19
20 public ILanguage language;
21
22 public ViewModelBase()
23 {
24 }
25
26 public ViewModelBase(IContainerExtension container)
27 {
28 this.language = container.Resolve<ILanguage>();
29 this.Region = container.Resolve<IRegionManager>();
30 this.Dialog = container.Resolve<IDialogService>();
31 this.Event = container.Resolve<IEventAggregator>();
32 this.Logger = container.Resolve<ILogger>();
33 }
34
35 private DelegateCommand _LoadedCommand;
36 public DelegateCommand LoadedCommand =>
37 _LoadedCommand ?? (_LoadedCommand = new DelegateCommand(ExecuteLoadedCommand));
38
39 /// <summary>
40 ///初始化界面加载
41 /// </summary>
42 public virtual void ExecuteLoadedCommand()
43 {
44
45 }
46
47 /// <summary>
48 /// 标记上一个视图时候被销毁
49 /// </summary>
50 public bool KeepAlive => false;
51
52 public virtual void ConfirmNavigationRequest(NavigationContext navigationContext, Action<bool> continuationCallback)
53 {
54 continuationCallback(true);
55 }
56
57 /// <summary>
58 /// 导航后的目标视图是否缓存
59 /// </summary>
60 /// <param name="navigationContext"></param>
61 /// <returns></returns>
62 public virtual bool IsNavigationTarget(NavigationContext navigationContext)
63 {
64 return false;
65 }
66
67 /// <summary>
68 /// 导航前
69 /// </summary>
70 /// <param name="navigationContext"></param>
71 public virtual void OnNavigatedFrom(NavigationContext navigationContext)
72 {
73
74 }
75
76 /// <summary>
77 /// 导航后
78 /// </summary>
79 /// <param name="navigationContext"></param>
80 public virtual void OnNavigatedTo(NavigationContext navigationContext)
81 {
82
83 }
84
85 /// <summary>
86 /// 分页一页多少数据
87 /// </summary>
88 public List<int> Limits { get; set; } = new List<int>()
89 {
90 10,20,30,40,50
91 };
92
93 /// <summary>
94 /// 总数据
95 /// </summary>
96 public int Total { get; set; }
97 }

复制代码

2、增加多语言服务，在ViewModel基类中注册利用
新增多语言接口ILanguage　　
　　

1 public interface ILanguage
2 {
3 /// <summary>
4 /// 查找当前字典中翻译文字
5 /// </summary>
6 /// <param name="key"></param>
7 /// <returns></returns>
8 object GetValue(string key);
9 /// <summary>
10 /// 根据Key在当前程序中查找翻译文件
11 /// </summary>
12 /// <param name="key"></param>
13 void LoadResourceKey(string key);
14 /// <summary>
15 /// 根据路径加载翻译文件
16 /// </summary>
17 /// <param name="path"></param>
18 void LoadPath(string path);
19 /// <summary>
20 /// 加载翻译文件
21 /// </summary>
22 /// <param name="languageDictionary"></param>
23 void LoadDictionary(ResourceDictionary languageDictionary);
24 /// <summary>
25 /// 刷新视图翻译效果
26 /// </summary>
27 void Refresh();
28 }

复制代码

View Code　　新增多语言扩展类LanguageExtension，继承MarkupExtension类（using System.Windows.Markup;）封装实现获取多语言信息的静态方法

四、增加Home项目，封装实现主窗口的菜单页面
　　1.编写类HomeModule，实现首页模块注册。将Home页面注入到SystemResource.Nav_MainContent中　
　　　　

1 public class HomeModule : IModule
2 {
3 public void OnInitialized(IContainerProvider containerProvider)
4 {
5 var regionManager = containerProvider.Resolve<IRegionManager>();
6
7 regionManager.RegisterViewWithRegion(SystemResource.Nav_MainContent, typeof(Home.Views.Home));
8 }
9
10 public void RegisterTypes(IContainerRegistry containerRegistry)
11 {
12
13 }
14 }
