如何在应用程序级别设置teleriks WPF IsTouchEnabled属性？

private void Application_Startup(object sender, StartupEventArgs e)
{
    // 获取Telerik的主题资源字典
    ResourceDictionary telerikThemeDictionary = Application.Current.Resources.MergedDictionaries
        .FirstOrDefault(d => d.Source != null && d.Source.OriginalString.Contains("Telerik.Windows.Controls.xaml"));

    if (telerikThemeDictionary != null)
    {
        // 获取Telerik的主题样式
        Style telerikThemeStyle = telerikThemeDictionary[typeof(Telerik.Windows.Controls.Theme)] as Style;

        if (telerikThemeStyle != null)
        {
            // 获取Telerik主题资源
            Telerik.Windows.Controls.ThemeResourceKey themeResourceKey = telerikThemeStyle.FindName("IsTouchEnabled") as Telerik.Windows.Controls.ThemeResourceKey;

            if (themeResourceKey != null)
            {
                // 设置IsTouchEnabled属性为true或false
                themeResourceKey.ResourceValue = true; // 启用触摸支持
                // themeResourceKey.ResourceValue = false; // 禁用触摸支持
            }
        }
    }
}
