WPF调用webapi并展示数据(一)：WPF页面的构建

有错误欢迎大家给我指正

本项目为WPF+Prism+net6.0

RestSharp调用API

UI为MaterialDesignThemes

EF Core自动生成数据库

效果展示：

项目启动后点击待办事项进入数据展示页

源码地址：绎Ronion/WPF.ToDo (gitee.com)

1.准备

1.1创建WPF项目

1.2 创建完成后，下载Nuget包：Prism.DryIoc、MaterialDesignThemes、Newtonsoft.Json

2.App.xaml的修改

2.1 添加

xmlns:prism="http://prismlibrary.com/"xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"

2.2 把最外层的Application标签改为prism:PrismApplication

2.3 引入资源文件，并删除StartupUri（不删除会重复加载，导致出现两个窗体）

App.xaml全文如下：

3.主页面

3.1 新建文件夹Views，在文件夹内新建窗口MainView.xaml(删除默认窗口)

3.2引用MaterialDesignThemes和Prism

xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"xmlns:prism="http://prismlibrary.com/"

主页面最终引用：

WindowStartupLocation=”CenterScreen” 启动时居中
WindowStyle=”None”隐藏边框
AllowsTransparency=”True”隐藏白边

3.3 这里设定为，点击导航栏的待办事项跳转到待办页，所以会用到UI组件的部分组件，会直接引用，我会把所有的代码贴出来

UI的源码地址，感兴趣的可以详细了解：

Releases · MaterialDesignInXAML/MaterialDesignInXamlToolkit (github.com)

3.4在App.xaml的下添加样式资源

3.5创建文件夹Common，在里面创建新文件MenuBar

/// 
/// 系统导航菜单实体类/// 
public class MenuBar : BindableBase{private string icon;/// 
/// 菜单图标/// 
public string Icon{get { return icon; }set { icon = value; }}private string title;/// 
/// 菜单名称/// 
public string Title{get { return title; }set { title = value; }}private string nameSpace;/// 
/// 菜单命名空间/// 
public string NameSpace{get { return nameSpace; }set { nameSpace = value; }}}

3.6创建文件夹Extensions，在里面创建新文件PrismManager

public static class PrismManager{/// 
/// 首页区域/// 
public static readonly string MainViewRegionName = "MainViewRegion";/// 
/// 设置页区域/// 
public static readonly string SettingsViewRegionName = "SettingsViewRegion";}

3.7创建文件夹ViewModels，在里面创建新文件MainViewModel

public class MainViewModel : BindableBase{public MainViewModel(IRegionManager regionManager){MenuBars = new ObservableCollection();CreateMenuBar();NavigateCommand = new DelegateCommand(Navigate);this.regionManager = regionManager;}private void Navigate(MenuBar obj){if (obj == null || string.IsNullOrWhiteSpace(obj.NameSpace))return;regionManager.Regions[PrismManager.MainViewRegionName].RequestNavigate(obj.NameSpace, back =>{});}public DelegateCommand NavigateCommand { get; private set; }//做导航private readonly IRegionManager regionManager;//ObservableCollection是一个动态属性集合，可以动态地添加和删除其中的元素private ObservableCollection menuBars;//动态属性集合public ObservableCollection MenuBars{get { return menuBars; }set{menuBars = value;RaisePropertyChanged();//通知属性值发生了变化}}void CreateMenuBar(){MenuBars.Add(new MenuBar() { Icon = "Home", Title = "首页", NameSpace = "IndexView" });MenuBars.Add(new MenuBar() { Icon = "NotebookOutline", Title = "待办事项", NameSpace = "ToDoView" });MenuBars.Add(new MenuBar() { Icon = "NotebookPlus", Title = "备忘录", NameSpace = "MemoView" });MenuBars.Add(new MenuBar() { Icon = "Cog", Title = "设置", NameSpace = "SettingsView" });} }

3.8在Views创建ToDoView，在ViewModels创建ToDoViewModel

3.9在App.xaml.cs注册，注意把Application改为PrismApplication

public partial class App : PrismApplication{protected override Window CreateShell(){return Container.Resolve();}protected override void RegisterTypes(IContainerRegistry containerRegistry){containerRegistry.RegisterForNavigation();}}

3.10主页的全部代码如下

3.6在MainView.xaml.cs内，添加各个按钮的事件

public MainView(){InitializeComponent();//点击导航栏后收回menuBar.SelectionChanged += (s, e) =>{drawerHost.IsLeftDrawerOpen = false;};//最小化btnMin.Click += (s, e) => { this.WindowState = WindowState.Minimized; };//最大化btnMax.Click += (s, e) =>{if (this.WindowState == WindowState.Maximized)this.WindowState = WindowState.Normal;elsethis.WindowState = WindowState.Maximized;};//关闭btnClose.Click += async (s, e) =>{this.Close();};//拖动窗口ColorZone.MouseMove += (s, e) =>{if (e.LeftButton == MouseButtonState.Pressed)this.DragMove();};//双击放大/缩小ColorZone.MouseDoubleClick += (s, e) =>{if (this.WindowState == WindowState.Normal)this.WindowState = WindowState.Maximized;elsethis.WindowState = WindowState.Normal;};}
