大致了解了Blazor和MAUI之后,尝试创建一个.NET MAUI Blazor应用。
需要注意的是: 虽然都叫MAUI,但.NET MAUI与.NET MAUI Blazor 并不相同,MAUI还是以xaml为主,而MAUI Blazor则是以razor为主。

大致了解了Blazor和MAUI之后,尝试创建一个.NET MAUI Blazor应用。
需要注意的是: 虽然都叫MAUI,但.NET MAUI.NET MAUI Blazor 并不相同,MAUI还是以xaml为主,而MAUI Blazor则是以razor为主。

这个系列还是以MAUI Blazor为主,要创建一个MAUI Blazor应用,需要安装Visual Studio 2022 17.3 或更高版本,并在安装程序上,勾选.NET Multi-platform App UI 开发!最好是升级到最新的.NET 7。
学习.NET MAUI Blazor(三)、创建.NET MAUI Blazor应用并使用AntDesignBlazor

创建.NET MAUI Blazor应用

打开Visual Studio 2022,选择创建新项目

.NET MAUI Blazor 需要注意的地方

.NET MAUI Blazor 运行在WebView2上,WebView2是微软推出的新一代用于桌面端混合开发的解决方案。它可以让本地应用程序(WinForm、WPF、WinUI、Win32)、移动应用程序(MAUI)轻松嵌入Web技术。WebView2 控件使用 Microsoft Edge 作为呈现引擎在客户端应用程序及App中显示 Web 内容。使用 WebView2 可以将 Web 代码嵌入到客户端应用程序及App中的不同部分,或在单个 WebView 实例中构建所有本机应用程序。

可以这么看MAUI Blazor, .NET MAUI 包含 BlazorWebView 控件,该控件运行将 Razor 组件呈现到嵌入式 Web View 中。 通过结合使用 .NET MAUI 和 Blazor,可以跨移动设备、桌面设备和 Web 重复使用一组 Web UI 组件。

说人话就是,它就是一个Hybrid App(混合应用) !

调试.NET MAUI Blazor

在windows上调试 MAUI Blazor应用,需要Windows 10 1809及更高版本上,并打开开发者模式。
windows 11上,位于设置->隐私和安全性->开发者选项->开发人员模式

这时,MAUI Blazor使用的是bootstrap样式以及open-iconic图标。
wwwroot/index.html中也可以看到

<link rel="stylesheet" href="css/bootstrap/bootstrap.min.css" /> 

现在已经有个很多基于Blazor的组件库,所以暂时把默认的bootstrap替换成第三方组件库,这里使用的是AntDesignBlazor

使用AntDesignBlazor 组件库

安装依赖:

PM> NuGetInstall-Package AntDesign.ProLayout -Version 0.13.1 

注入AntDesign

MauiProgram.cs注入AntDesign 服务与设置基本配置,完整的MauiProgram.cs代码

using Microsoft.Extensions.Logging; using MauiBlazorApp.Data;  namespace MauiBlazorApp;  public static class MauiProgram { 	public static MauiApp CreateMauiApp() 	{ 		var builder = MauiApp.CreateBuilder(); 		builder 			.UseMauiApp<App>() 			.ConfigureFonts(fonts => 			{ 				fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular"); 			});  		builder.Services.AddMauiBlazorWebView();  #if DEBUG 		builder.Services.AddBlazorWebViewDeveloperTools(); 		builder.Logging.AddDebug(); #endif  		builder.Services.AddSingleton<WeatherForecastService>();         //注入AntDesign         builder.Services.AddAntDesign(); 		//基本配置 		builder.Services.Configure<ProSettings>(settings => 		{             settings.NavTheme = "light";             settings.Layout = "side";             settings.ContentWidth = "Fluid"; 			settings.FixedHeader = false; 			settings.FixSiderbar = true;             settings.Title = "DotNet宝藏库"; 			settings.PrimaryColor = "daybreak"; 			settings.ColorWeak = false; 			settings.SplitMenus= false; 			settings.HeaderRender= true; 			settings.FooterRender= false; 			settings.MenuRender= true; 			settings.MenuHeaderRender= true; 			settings.HeaderHeight = 48;  		}); 		return builder.Build(); 	} }  

配置项都写上了。参数含义从表达的意思就能看出来,不做注释了!

引入样式

打开wwwroot/index.html。由于我们使用的是AntDesign,所以需要改造下index.html,修改后内容如下:

<!DOCTYPE html> <html lang="en"> <head>     <meta charset="utf-8" />     <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no, viewport-fit=cover" />     <title>DotNet宝藏库</title>     <base href="/" />          <link href="_content/AntDesign/css/ant-design-blazor.css" rel="stylesheet" />     <link rel="stylesheet" href="_content/AntDesign.ProLayout/css/ant-design-pro-layout-blazor.css" /> </head>  <body>      <div class="status-bar-safe-area"></div>      <div id="app">         <style>             html,             body,             #app {                 height: 100%;

加入命名空间

_Imports.razor添加AntDesign命名空间:

@using System.Net.Http @using Microsoft.AspNetCore.Components.Forms @using Microsoft.AspNetCore.Components.Routing @using Microsoft.AspNetCore.Components.Web @using Microsoft.AspNetCore.Components.Web.Virtualization @using Microsoft.JSInterop @using MauiBlazorApp @using MauiBlazorApp.Shared //引入AntDesign @using AntDesign 

设置容器

Main.razor中加入<AntContainer />

<Router AppAssembly="@typeof(Main).Assembly">     <Found Context="routeData">         <RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" />         <FocusOnNavigate RouteData="@routeData" Selector="h1" />     </Found>     <NotFound>         <LayoutView Layout="@typeof(MainLayout)">             <p role="alert">Sorry, there's nothing at this address.</p>         </LayoutView>     </NotFound> </Router> <!--设置容器--> <AntContainer />  

修改 MainLayout

  • 修改MainLayout.razor
  • MainLayout.razor中默认布局删除
  • 引入AntDesign.ProLayout
  • 设置布局为AntDesign.ProLayout
  • 构造菜单、页脚的链接、版权
  • wwwroot目录下新建个文件夹images,把提前准备好的logo放进去

完整代码如下:

@using AntDesign.ProLayout @inherits LayoutComponentBase  <AntDesign.ProLayout.BasicLayout      Logo="@("images/logo.png")"     MenuData="MenuData">     <ChildContent>         @Body     </ChildContent>     <FooterRender>         <FooterView Copyright="MauiBlazorApp" Links="Links"></FooterView>     </FooterRender> </AntDesign.ProLayout.BasicLayout> <SettingDrawer />  @code {     private readonly MenuDataItem[] MenuData =         {         new MenuDataItem         {             Path = "/",             Name = "Home",             Key = "Home",             Icon = "home"         },         new MenuDataItem         {             Path = "/Counter",             Name = "Counter",             Key = "Counter",             Icon = "plus"         },         new MenuDataItem         {             Path = "/FetchData",             Name = "FetchData",             Key = "FetchData",             Icon = "cloud"         }     };     private readonly LinkItem[] Links =     {         new LinkItem         {             Key = "DotNet宝藏库",             Title = "基于Ant Design Blazor",             Href = "https://antblazor.com",             BlankTarget = true         }     }; } 

这时可以把项目中无用的内容删除掉了,如Shared/NavMenu.razorwwwroot/css文件。
由于删除掉了css文件夹,页面元素肯定没有样式了。那么就简单的改造下默认的几个页面!

改造默认页面

index.razor

打开Pages/Index.razor,将演示组件SurveyPrompt 删掉。顺便把Shared/SurveyPrompt.razor也删除掉。将<h1>Hello, world!</h1>
替换为Ant Design组件。

@page "/"  <Title Level="1">Hello,DotNet宝藏库</Title>  <br /> <Text Type="success">欢迎关注我的公众号!</Text>  

Counter.razor

打开 Pages/Counter.razor,将代码改为如下:

@page "/counter"  <Title Level="2">HCounter</Title> <Divider /> <p role="status">Current count: @currentCount</p>  <Button @onclick="IncrementCount" Type="primary">AntDesign 按钮</Button> @code {     private int currentCount = 0;      private void IncrementCount()     {         currentCount++;     } }  

FetchData.razor

打开Pages/FetchData.razor,将数据表格替换为Ant Design,删除页面所有代码,替换为Ant Design的示例!

@page "/fetchdata" @using System.ComponentModel @using AntDesign.TableModels @using System.Text.Json  @using MauiBlazorApp.Data @inject WeatherForecastService ForecastService  <Table @ref="table"        TItem="WeatherForecast"        DataSource="@forecasts"        Total="_total"        @bind-PageIndex="_pageIndex"        @bind-PageSize="_pageSize"        @bind-SelectedRows="selectedRows"        OnChange="OnChange">     <Selection Key="@(context.Id.ToString())" />     <PropertyColumn Property="c=>c.Id" Sortable />     <PropertyColumn Property="c=>c.Date" Format="yyyy-MM-dd" Sortable />     <PropertyColumn Property="c=>c.TemperatureC" Sortable />     <PropertyColumn Title="Temp.
