我正在使用WPF类库，而不是应用程序。这是我在c＃中制作的Label的示例，我想使用XAML对其进行“样式化”。

   private void CreateElement(int i)
    {
        UIElementOut[i] = new Label();
        var uiElement = (Label)UIElementOut[i];
        uiElement.HorizontalAlignment = HorizontalAlignment.Center;
        uiElement.VerticalAlignment = VerticalAlignment.Center;
        uiElement.FontFamily = new FontFamily(FFontInput[i]);
        uiElement.FontSize = Convert.ToDouble(FontSizeIn[i]);
        uiElement.Content = TextIn[i];
        Brush BgBrushColor = new SolidColorBrush(RGBAToMediaColor(FBgCol[i]));
        Brush FgBrushColor = new SolidColorBrush(RGBAToMediaColor(FFgCol[i]));
        uiElement.Background = BgBrushColor;
        uiElement.Foreground = FgBrushColor;
        Uri uri = new Uri("Styles/LabelStyle.xaml", UriKind.Relative);
        StreamResourceInfo info = Application.GetContentStream(uri);
        System.Windows.Markup.XamlReader reader = new System.Windows.Markup.XamlReader();
        ResourceDictionary myResourceDictionary = (ResourceDictionary)reader.LoadAsync(info.Stream);
        Application.Current.Resources.MergedDictionaries.Add(myResourceDictionary);
        Style myLabelStyle = myResourceDictionary["LabelStyle"] as Style;
        uiElement.Style = myLabelStyle;
    }

为此，我有包含我的LabelStyle的ressourcedictionnary，所有内容都可以正常编译。

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" …

参考：Ookii.Dialogs.Wpf.VistaOpenFileDialog：

我正在尝试像这样设置 Ookii 的 VistaOpenFileDialog 初始目录：

    VistaOpenFileDialog vfb = new VistaOpenFileDialog();
        vfb.Multiselect = true;
        vfb.Title = "pouet";
        vfb.RestoreDirectory = false;
        vfb.InitialDirectory = @"C:\Users\";
        if (vfb.ShowDialog() ?? false)
        {
            this.Dispatcher.Invoke(DispatcherPriority.Send, new Action(delegate
            {
                for (var i = 0; i < vfb.FileNames.Length; i++)
                {
                    FileDisplay.Add(vfb.FileNames[i]);                    
                }
            }));
        }
    }

    private void AddFiles_Click(object sender, RoutedEventArgs e)
    {
        t = new Thread(new ThreadStart(AddFileDialog));
        t.SetApartmentState(ApartmentState.STA);
        t.Start();
    }

但是无论我尝试什么都不起作用，对话框一开始永远不会被初始目录打开，也永远不会被初始目录重新打开。我仍然可以毫无问题地选择文件夹的文件。

我已经尝试了以下（作为测试）：

vfb.InitialDirectory = @"C:\Users\";
vfb.InitialDirectory = "C:\\Users\\";
vfb.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop).ToString();

也试过 restoredirectory true 或 false …

我正在尝试为按钮创建样式，特别是更改 IsMouseOver 样式（必须通过控件模板覆盖它）。我正在尝试这段代码（我必须使用 c#，没有 xaml），但按钮只是变成黄色，IsMouseOver 没有做任何事情。

private void CreateElement(int i)
{
    UIElementOut[i] = new Button();
    var uiElement = (Button)UIElementOut[i];
    uiElement.Width = 100;
    uiElement.Height = 100;
    uiElement.VerticalAlignment = VerticalAlignment.Center;
    uiElement.HorizontalAlignment = HorizontalAlignment.Center;
    uiElement.Content = TextIn[i];
    uiElement.FontFamily = new FontFamily(FFontInput[i]);
    uiElement.FontSize = Convert.ToDouble(FontSizeIn[i]);

    Style MyButtonStyle = new Style();
    ControlTemplate templateButton = new ControlTemplate(typeof(Button));
    FrameworkElementFactory elemFactory = new FrameworkElementFactory(typeof(Button));
    elemFactory.Name = "myButton";
    elemFactory.SetValue(Button.BackgroundProperty, Brushes.Yellow);
    templateButton.VisualTree = elemFactory;
    elemFactory.AppendChild(new FrameworkElementFactory(typeof(ContentPresenter)));

    Trigger templateTrigger = new Trigger { Property = Button.IsPressedProperty, Value = true };
    templateTrigger.Setters.Add(new …
