c#中的wpf只用代码创建wpf应用程序

window1.cs

using System.Windows;using System.Windows.Controls;using System.Windows.Markup;namespace WpfApp3{    class window1:Window    {        private Button button1;        public window1() {            InitializeComponent();        }        private void InitializeComponent() {            //设置窗体            this.Width = 285;            this.Height = 250;            this.Left = this.Top = 100;            this.Title = "code-Only window";            //创建停靠面板对象            DockPanel panal = new DockPanel();            button1 = new Button();            button1.Content = "please click me";            button1.Margin = new Thickness(30);            button1.Click += button1_click;            IAddChild container = panal;            container.AddChild(button1);            //容器等于当前对象            container = this;            container.AddChild(panal);//加上panal面板        }        private void button1_click(object sender,RoutedEventArgs e) {            button1.Content = "thank you";        }    }}

program.cs

using System;using System.Windows;namespace WpfApp3{    class program:Application    {        [STAThread()]     //单线程        static void Main() {            program app = new program();            app.MainWindow = new window1();            app.MainWindow.ShowDialog();        }    }}
