.net 8 发布了，试下微软最近强推的MAUI

本文主要是介绍.net 8 发布了，试下微软最近强推的MAUI，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

先看下实现的效果：

下面发下XAML文件：

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"x:Class="MauiApp2.MainPage"><ScrollView><VerticalStackLayoutPadding="30,0"Spacing="25"><Label x:Name="txt_label" Text="Value :0 "></Label><Slider x:Name="slider_1" Minimum="0" Maximum="1"  ValueChanged="Slider_ValueChanged" /><ImageSource="dotnet_bot.png"HeightRequest="185"Aspect="AspectFit"SemanticProperties.Description="dot net bot in a race car number eight" /><LabelText="Hello, World!"Style="{StaticResource Headline}"SemanticProperties.HeadingLevel="Level1" /><LabelText="Welcome to &#10;.NET Multi-platform App UI"Style="{StaticResource SubHeadline}"SemanticProperties.HeadingLevel="Level2"SemanticProperties.Description="Welcome to dot net Multi platform App U I" /><Buttonx:Name="CounterBtn"Text="Click me" SemanticProperties.Hint="Counts the number of times you click"Clicked="OnCounterClicked"HorizontalOptions="Fill" /></VerticalStackLayout></ScrollView></ContentPage>

.cs文件：

namespace MauiApp2
{public partial class MainPage : ContentPage{int count = 0;public MainPage(){InitializeComponent();}private void OnCounterClicked(object sender, EventArgs e){count++;if (count == 1)CounterBtn.Text = $"Clicked {count} time";elseCounterBtn.Text = $"Clicked {count} times";SemanticScreenReader.Announce(CounterBtn.Text);}private void Slider_ValueChanged(object sender, ValueChangedEventArgs e){this.txt_label.Text = this.slider_1.Value.ToString();}}}

下一个示例实现调用手机的蓝牙或者一些设备。
