WPF学习笔记-纯代码实现WPF程序

1，分析WPF引用和继承的类

2，手写界面

3，手写启动程序

界面代码，cs类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;  //三个引用
using System.Windows.Controls;
using System.Windows.Markup;

namespace WPFdemo2
{
    public class Windows1 : Window   
    {
        private Button button1 = null;
        public Windows1()
        {
            //模仿建立一个初始化界面方法
            InitializeComponent();
        }
        private void InitializeComponent()
        {
            //设置窗体基本信息
            this.Height = 100;
            this.Width = 200;
            this.Title = "Code WPF";

            //创建窗体面板
            DockPanel panel = new DockPanel();
            //创建面板内元素对象，比如Button
            button1 = new Button();
            button1.Height = 50;
            button1.Width = 100;
            button1.Content = "Pls Click";
            //元素的事件
            button1.Click += Button1_Click;

            ////添加容器，指定面板
            //IAddChild container = panel;
            ////面板里面加button元素
            //container.AddChild(button1);
            ////改变面板指向当前对象
            //container = this;
            ////当前对象在加子元素面板
            //container.AddChild(panel);

            //或者  直接指定容器为当前对象
            IAddChild container = this;
            //容器加面板元素
            container.AddChild(panel);
            //面板加子元素
            panel.Children.Add(button1);

        }

        private void Button1_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("Hello Code WPF");
        }
    }
}

启动程序代码，cs类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
namespace WPFdemo2
{
    //继承运行程序
    public  class Program:Application
    {
        //需要单线程启动
        [STAThread]
        static void Main()
        {
            Program app = new Program();
            app.MainWindow = new Windows1();
            app.MainWindow.ShowDialog();
        }
    }
}
