.Net-Avalonia学习笔记（二）-HelloWorld与简易登录页

一、HelloWorld

1、创建解决方案

2、试运行

3、修改代码

  修改MainView.axaml文件，将“Welcome to Avalonia!”改为“HelloWorld！”;

4、结果

二、创建登录窗体

1、SignInWindow.axaml

<Window xmlns="https://github.com/avaloniaui"
        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"
        mc:Ignorable="d" d:DesignWidth="600" d:DesignHeight="450" Width="600" Height="450"
        x:Class="AvaloniaUI_Simple.SignInWindow"
        Title="登录窗体">
	<Grid>
		<StackPanel Orientation="Vertical">
			<Panel Height="60"/>
			<Label Content="欢迎登录" FontSize="40" VerticalAlignment="Center" HorizontalAlignment="Center"/>
			<Panel Height="40"/>
			<StackPanel Width="290" Orientation="Horizontal" HorizontalAlignment="Center">
				<Label Content="账户：" VerticalAlignment="Center" HorizontalAlignment="Left" FontSize="18"/>
				<TextBox Name="txtName" Width="224" FontSize="20"/>
			</StackPanel>
			<Panel Height="12"/>
			<StackPanel Width="290" Orientation="Horizontal" HorizontalAlignment="Center">
				<Label Content="密码：" VerticalAlignment="Center" HorizontalAlignment="Left" FontSize="18"/>
				<TextBox Name="txtPwd" Width="224" FontSize="20"/>
			</StackPanel>
			<Panel Height="20"/>
			<!-- Orientation="Horizontal"-->
			<Button Content="登录" Name="Btn_SignIn" FontSize="20" Foreground="White" Width="282" Height="48" Background="#375778" HorizontalAlignment="Center" VerticalAlignment="Center" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Cursor="Hand" />
			<Panel Height="10"/>
			<Button Content="注册" Name="Btn_Register" FontSize="20"  Foreground="White" Width="282" Height="48" Background="#375778" HorizontalAlignment="Center" VerticalAlignment="Center" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" />
		</StackPanel>
	</Grid>
</Window>

2、MainWindow.axaml添加按钮进行跳转

<Window xmlns="https://github.com/avaloniaui"
        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"
        mc:Ignorable="d" d:DesignWidth="800" d:DesignHeight="450" Width="800" Height="450"
        x:Class="AvaloniaUI_Simple.MainWindow"
        Title="AvaloniaUI_Simple -Bili执笔小白">
	<Grid>
		<StackPanel Margin="15">
			<Label Content="HelloWorld！"/>
			<Panel Height="10" />
			<Button Content="登录" Width="74" Name="Btn_SignIn" HorizontalContentAlignment="Center" Click="BtnSignIn_Click"/>
		</StackPanel>
	</Grid>
</Window>

3、MainWindow.axaml.cs

using Avalonia.Controls;
using Avalonia.Interactivity;
using System.Diagnostics;

namespace AvaloniaUI_Simple
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        /// <summary>
        /// 打开 登录页
        /// </summary>
        /// <param name="source"></param>
        /// <param name="args"></param>
        public void BtnSignIn_Click(object source, RoutedEventArgs args)
        {
            SignInWindow signInWindow = new SignInWindow();
            signInWindow.Show();
        }
    }
}
