    int DataContaxt = 10;
}

Answer 1

也许只是将DataContext字段设置为静态

Answer 2

Make Method and fields which you want to use in another class of DetailedBookView static . Doing so, you can use these methods and fields with the class name directly.

public partial class DetailedBookView : UserControl
{
    static int DataContaxt = 10;
}

Now you can use DataContaxt directly as:

public partial class MainWindow : Window
{    
    int a = DetailedBookView.DataContaxt;

}
