只使用C#代码创建WPF应用程序

只使用C#代码创建WPF应用程序

1. 新建一个WPF项目，将App.Xaml和MainWindow.xaml删除

2. 创建一个Window1的类，并继承自Window。注意需要添加三个using引用 ```csharp using System.Windows; using System.Windows.Controls; using System.Windows.Markup;

namespace 项目6 { class Window1:Window { private Button button1;

    public Window1()
    {
        InitializeComponeent();
    }
    private void InitializeComponeent()
    {
        //设置窗体大小
        this.Width = 600;
        this.Height = 450;
        this.Left = this.Top = 100;
        Title = "Code-Only Window";
        DockPanel panel=new DockPanel();//创建面板
        button1 = new Button();
        button1.Content = "Please Click me!";
        button1.Margin=new Thickness(30);
        button1.Click += Button1_Click;
        IAddChild container = panel;
        container.AddChild(button1);
        container = this;
        container.AddChild(panel);
    }
    private void Button1_Click(object sender, RoutedEventArgs e)
    {
        button1.Content = "Thank you!";
    }
}

}

   31. 再新建个Program.cs类，作为启动程序：
```csharp
using System;
using System.Windows;
namespace 项目6 {
    class Program :Application{
        [STAThread()]
        static void Main()
        {
            Program app=new Program();
            app.MainWindow=new Window1();
            app.MainWindow.ShowDialog();
        }
    }
}
