在WPF中创建一个公共窗口

using System.Windows;

public class CommonWindow : Window
{
    // 在这里添加公共属性和方法
}

using System.Windows;

public partial class MainWindow : CommonWindow
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

using System.Windows;

public class CommonWindow : Window
{
    public double TitleBarHeight
    {
        get { return (double)GetValue(TitleBarHeightProperty); }
        set { SetValue(TitleBarHeightProperty, value); }
    }

    public static readonly DependencyProperty TitleBarHeightProperty =
        DependencyProperty.Register("TitleBarHeight", typeof(double), typeof(CommonWindow), new PropertyMetadata(30.0));
}

using System.Windows;

public partial class MainWindow : CommonWindow
{
    public MainWindow()
    {
        InitializeComponent();
        TitleBarHeight = 50;
    }
}
