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：

<prism:PrismApplication x:Class="ToDoDemo.App"             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"             xmlns:local="clr-namespace:ToDoDemo"             xmlns:prism="http://prismlibrary.com/"             xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes">    <Application.Resources>        <ResourceDictionary>            <ResourceDictionary.MergedDictionaries>                <materialDesign:BundledTheme BaseTheme="Dark" PrimaryColor="DeepPurple" SecondaryColor="Lime" />                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />            </ResourceDictionary.MergedDictionaries>        </ResourceDictionary>            </Application.Resources></prism:PrismApplication>

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

<Window x:Class="ToDoDemo.Views.MainView"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"        xmlns:local="clr-namespace:ToDoDemo.Views"        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"        xmlns:i="http://schemas.microsoft.com/xaml/behaviors"        xmlns:prism="http://prismlibrary.com/"        xmlns:ext="clr-namespace:ToDoDemo.Extensions"        mc:Ignorable="d"        Height="450" Width="800"        WindowStyle="None"        AllowsTransparency="True"        WindowStartupLocation="CenterScreen"></Window>

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</ResourceDictionary.MergedDictionaries>下添加样式资源

<Style x:Key="MyListBoxItemStyle" TargetType="ListBoxItem">    <Setter Property="MinHeight" Value="40" />    <Setter Property="Template">        <Setter.Value>            <ControlTemplate TargetType="{x:Type ListBoxItem}">                <Grid>                    <Border x:Name="borderHeader" />                    <Border x:Name="border" />                    <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />                </Grid>                <ControlTemplate.Triggers>                    <Trigger Property="IsSelected" Value="True">                        <Setter TargetName="borderHeader" Property="BorderThickness" Value="4,0,0,0" />                        <Setter TargetName="borderHeader" Property="BorderBrush" Value="{DynamicResource PrimaryHueLightBrush}" />                        <Setter TargetName="border" Property="Background" Value="{DynamicResource PrimaryHueLightBrush}" />                        <Setter TargetName="border" Property="Opacity" Value="0.2" />                    </Trigger>                    <Trigger Property="IsMouseOver" Value="True">                        <Setter TargetName="border" Property="Background" Value="{DynamicResource PrimaryHueLightBrush}" />                        <Setter TargetName="border" Property="Opacity" Value="0.2" />                    </Trigger>                </ControlTemplate.Triggers>            </ControlTemplate>        </Setter.Value>    </Setter></Style>

3.5创建文件夹Common，在里面创建新文件MenuBar

/// <summary>/// 系统导航菜单实体类/// </summary>public class MenuBar : BindableBase{    private string icon;    /// <summary>    /// 菜单图标    /// </summary>    public string Icon    {        get { return icon; }        set { icon = value; }    }    private string title;    /// <summary>    /// 菜单名称    /// </summary>    public string Title    {        get { return title; }        set { title = value; }    }    private string nameSpace;    /// <summary>    /// 菜单命名空间    /// </summary>    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{    /// <summary>    /// 首页区域    /// </summary>    public static readonly string MainViewRegionName = "MainViewRegion";    /// <summary>    /// 设置页区域    /// </summary>    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<MenuBar>();        CreateMenuBar();        NavigateCommand = new DelegateCommand<MenuBar>(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<MenuBar> 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<MenuBar> menuBars;//动态属性集合    public ObservableCollection<MenuBar> 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<MainView>();    }    protected override void RegisterTypes(IContainerRegistry containerRegistry)    {        containerRegistry.RegisterForNavigation<ToDoView, ToDoViewModel>();    }}

3.10主页的全部代码如下

<Window x:Class="ToDoDemo.Views.MainView"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"        xmlns:local="clr-namespace:ToDoDemo.Views"        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"        xmlns:i="http://schemas.microsoft.com/xaml/behaviors"        xmlns:prism="http://prismlibrary.com/"        xmlns:ext="clr-namespace:ToDoDemo.Extensions"        mc:Ignorable="d"        Height="450" Width="800"        WindowStyle="None"        AllowsTransparency="True"        WindowStartupLocation="CenterScreen">    <materialDesign:DialogHost DialogTheme="Inherit" Identifier="RootDialog"                             SnackbarMessageQueue="{Binding ElementName=MainSnackbar, Path=MessageQueue}">        <materialDesign:DrawerHost x:Name="drawerHost"                                  IsLeftDrawerOpen="{Binding ElementName=MenuToggleButton, Path=IsChecked}">            <materialDesign:DrawerHost.LeftDrawerContent>                <DockPanel MinWidth="220">                    <!--侧边栏-->                    <ListBox ItemContainerStyle="{StaticResource MyListBoxItemStyle}"                          ItemsSource="{Binding MenuBars}" x:Name="menuBar">                        <i:Interaction.Triggers>                            <i:EventTrigger EventName="SelectionChanged">                                <i:InvokeCommandAction Command="{Binding NavigateCommand}"                                                    CommandParameter="{Binding ElementName=menuBar,Path=SelectedItem}"/>                            </i:EventTrigger>                        </i:Interaction.Triggers>                        <ListBox.ItemTemplate>                            <DataTemplate>                                <StackPanel Background="Transparent" Orientation="Horizontal">                                    <materialDesign:PackIcon Margin="15,0" Kind="{Binding Icon}"/>                                    <TextBlock Text="{Binding Title}" Margin="10,0"/>                                </StackPanel>                            </DataTemplate>                        </ListBox.ItemTemplate>                    </ListBox>                </DockPanel>            </materialDesign:DrawerHost.LeftDrawerContent>            <DockPanel>                <materialDesign:ColorZone Padding="16" x:Name="ColorZone"                                       materialDesign:ElevationAssist.Elevation="Dp4"                                       DockPanel.Dock="Top" Mode="PrimaryMid">                    <DockPanel LastChildFill="True">                        <!--最小化、最大化、关闭-->                        <StackPanel DockPanel.Dock="Right" Orientation="Horizontal">                            <Button x:Name="btnMin" Content="—" Style="{StaticResource MaterialDesignFlatMidBgButton}" />                            <Button x:Name="btnMax" Content="☐" Style="{StaticResource MaterialDesignFlatMidBgButton}" />                            <Button x:Name="btnClose" Content="✕" Style="{StaticResource MaterialDesignFlatMidBgButton}" />                        </StackPanel>                        <!--三横杠-->                        <StackPanel Orientation="Horizontal">                            <ToggleButton x:Name="MenuToggleButton" IsChecked="False"                                       AutomationProperties.Name="HamburgerToggleButton"                                       Style="{StaticResource MaterialDesignHamburgerToggleButton}" />                        </StackPanel>                    </DockPanel>                </materialDesign:ColorZone>                <ContentControl prism:RegionManager.RegionName="{x:Static ext:PrismManager.MainViewRegionName}" />            </DockPanel>        </materialDesign:DrawerHost>    </materialDesign:DialogHost></Window>

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;        else            this.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;        else            this.WindowState = WindowState.Normal;    };}
