如何在代码隐藏中添加资源

Question

如何在代码中添加以下资源？

<Window.Resources>
    <ResourceDictionary>
        <FrameworkElement x:Key="OpenHand" Cursor="pack://application:,,,/Resources/openhand.cur"/>
    </ResourceDictionary>
</Window.Resources>

Answer 1

在C＃Code-Behind中，您可以这样做：

ResourceDictionary rd = new ResourceDictionary();
FrameworkElement fe = new FrameworkElement() 
{
   Cursor = new Cursor("pack://application:,,,/Resources/openhand.cur") 
};
rd.Add("OpenHand", fe);
Application.Current.Resources = rd;

如果您的资源中有其他ResourceDictionary，您应将rd添加到资源，而不是 将资源设置为rd ：

Application.Current.Resources.MergedDictionaries.Add(rd);

Answer 2

试试这个：

 public MainWindow()
        {
            InitializeComponent();
            DataContext = new MainViewModel();
            var res = new ResourceDictionary();
            var frame = new FrameworkElement() 
            {
             Cursor = new Cursor("pack://application:,,,/Resources/openhand.cur") 
            };
            res .Add("framework", frame);
            this.Resources.Add(rd);
        }

Answer 3

var element = Application.Current.MainWindow.Resources["OpenHand"] as FrameworkElement;
