一、创建实体模型-About.cs
using System;
namespace Test.Models
{
/// <summary>
/// 关于页
/// </summary>
public class About
{
/// <summary>
/// App标题
/// </summary>
public string Title=> AppInfo.Name;
/// <summary>
/// App版本
/// </summary>
public string Version => AppInfo.VersionString;
/// <summary>
/// 信息
/// </summary>
public string Text => "Holle World!";
}
}
二、创建视图-AboutPage.xaml
<?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"
xmlns:models="clr-namespace:Test.Models"
x:Class="Test.Views.AboutPage"
Title="关于页">
<ContentPage.BindingContext>
<models:About />
</ContentPage.BindingContext>
<VerticalStackLayout>
<HorizontalStackLayout Spacing="10">
<Image Source="dotnet_bot.png"
SemanticProperties.Description="你好!"
HeightRequest="64" />
<Label FontSize="22" FontAttributes="Bold" Text="{Binding Title}" VerticalOptions="End" />
<Label FontSize="22" Text="{Binding Version}" VerticalOptions="End" />
</HorizontalStackLayout>
<Label Text="{Binding Text}" />
</VerticalStackLayout>
</ContentPage>
1、AboutPage.xaml视图页引用模型类所在的路径:xmlns:models="clr-namespace:Test.Models"
;
2、AboutPage.xaml根元素ContentPage
添加BindingContext
属性用来绑定数据:
<ContentPage.BindingContext>
<models:About />
</ContentPage.BindingContext>
3、使用 {Binding ..}
来给控件的属性绑定实体中的数据,例如:<Label Text="{Binding Version}" />
