被标记的答案是第一部分。

The marked answer is the first part.

第二部分是，你必须创建一个防爆pressionConverter并注入到序列化进程。这个细节在这里：

The second part is that you have to create an ExpressionConverter and inject it into the serialization process. Details for this are here:

推荐答案

这是我所做的是使用的XamlWriter到WPF对象保存为一个字符串的最简单方法。 Save方法将序列化逻辑树中的对象及其所有孩子。现在，您可以创建一个新对象，并用XamlReader加载它。

The simplest way that I've done it is to use a XamlWriter to save the WPF object as a string. The Save method will serialize the object and all of its children in the logical tree. Now you can create a new object and load it with a XamlReader.

例如：
写对象为XAML（假设对象是一个Grid控件）：

ex: Write the object to xaml (let's say the object was a Grid control):

string gridXaml = XamlWriter.Save(myGrid);

加载到一个新的对象：

Load it into a new object:

StringReader stringReader = new StringReader(gridXaml);
XmlReader xmlReader = XmlReader.Create(stringReader);
Grid newGrid = (Grid)XamlReader.Load(xmlReader);
