有什么方法可以提取底层Xaml?

问题描述

限时删除！！

无论如何都可以从控件中提取底层 xaml.

Is there anyway to extract the underlying xaml from a control.

IE.我有一个名为 fooBox 的文本框.我可以在运行时从代表文本框的文本框中获取 xaml 吗?

IE. I have a textbox named fooBox. Can I get xaml back from the textbox at runtime that represents the textbox?

推荐答案

这向您展示了完整的生命周期(从控件到 XAML 再到控件).如您所见，

This shows you the full lifecycle (from control to XAML back to control).As you can see,

string s = XamlWriter.Save(value);

是您可能关心的有趣部分.

is the interesting part you might care about.

    /// <summary>
    /// Clones a given UIElement.  Please note that any events, animations, etc
    /// on the source item may not carry over to the cloned object.
    /// </summary>
    /// <param name="value">UIElement to clone.</param>
    /// <returns>A shallow clone of the source element.</returns>
    public static UIElement CloneUIElement(UIElement value)
    {
        if (value == null)
        {
            return null;
        }

        string s = XamlWriter.Save(value);
        StringReader stringReader = new StringReader(s);
        XmlReader xmlReader = XmlTextReader.Create(stringReader, new XmlReaderSettings());
        return (UIElement)XamlReader.Load(xmlReader);
    }
