Question

我想使用Visual Studio的文件查找（或其他一些机制）来查找我的解决方案中的所有隐式WPF样式（所有没有Key的样式因此自我应用全球范围内）。如何实现这一目标？

我们必须检查Key资源的Style。如果Key的值为System.Type类型且其基类为System.Windows.FrameworkElement，则表示它是隐式Style。

static List<Style> _styles = new List<Style>();
private void Button_Click(object sender, RoutedEventArgs e)
{
    // Check for Application
    var appResDict = Application.Current.Resources;
    foreach (DictionaryEntry entry in appResDict)
    {
        if ((entry.Key is System.Type) && ((Type)entry.Key).IsSubclassOf(typeof(System.Windows.FrameworkElement)))
            _styles.Add((Style)entry.Value);
    }

    // Check for Window
    var resDict = this.Resources;
    foreach (DictionaryEntry entry in resDict)
    {
        if ((entry.Key is System.Type) && ((Type)entry.Key).IsSubclassOf(typeof(System.Windows.FrameworkElement)))
            _styles.Add((Style)entry.Value);
    }

    // Check for all other controls
    MainWindow.EnumVisual(this);

    MessageBox.Show(_styles.Count.ToString());
}

// Enumerate all the descendants of the visual object.
static public void EnumVisual(Visual myVisual)
{
    for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
    {
        // Retrieve child visual at specified index value.
        Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);

        // Check for implicit style
        if (childVisual is FrameworkElement)
        {
            FrameworkElement elem = (FrameworkElement)childVisual;
            var resDict = elem.Resources;

            foreach (DictionaryEntry entry in resDict)
            {
                if ((entry.Key is System.Type) && ((Type)entry.Key).IsSubclassOf(typeof(System.Windows.FrameworkElement)))
                    _styles.Add((Style)entry.Value);
            }
        }


        // Enumerate children of the child visual object.
        EnumVisual(childVisual);
    }
}

如何在我的解决方案中找到所有隐式WPF样式？
