第一个WPF桌面应用程序

安装Visual Studio

创建应用程序项目

工作区大概长这样子

写代码测试

编辑MainWindow.xaml（类似安卓开发的xml语言）

在Grid布局中添加

<TextBlock HorizontalAlignment="Left" Margin="252,47,0,0" TextWrapping="Wrap" Text="Select a message option and then choose the Display button." VerticalAlignment="Top"/>
        <RadioButton x:Name="HelloButton" Content="Hello" IsChecked="True" HorizontalAlignment="Left" Margin="297,161,0,0" VerticalAlignment="Top" Height="30.24" Width="78.107"/>
        <RadioButton x:Name="GoodbyeButton" Content="Goodbye" HorizontalAlignment="Left" Margin="488,161,0,0" VerticalAlignment="Top"/>
        <Button Content="Display" Click="Button_Click_1" HorizontalAlignment="Left" Height="40.061" Margin="346.107,245.449,0,0" VerticalAlignment="Top" Width="201.689"/>

(可进行拖拽，放大缩小的图形化操作)

在MainWindow.xmal.ca添加按钮事件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace WpfApp1
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
                            if (HelloButton.IsChecked == true)
                                {
                               MessageBox.Show("Hello.","提示");
                                }
                           else if (GoodbyeButton.IsChecked == true)
                            {
                                MessageBox.Show("Goodbye.","提示");
                            }
         }
    }
}

其中Button_Click_1与之前xaml中Click对应
