Anybody have a good example how to deep clone a WPF object, preserving databindings?

标记的答案是第一部分.

The marked answer is the first part.

第二部分是您必须创建一个 ExpressionConverter 并将其注入序列化过程中.详细信息在这里:

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

我所做的最简单的方法是使用 XamlWriter 将 WPF 对象保存为字符串.Save 方法将序列化逻辑树中的对象及其所有子项.现在您可以创建一个新对象并使用 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:将对象写入 xaml(假设该对象是一个 Grid 控件):

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

string gridXaml = XamlWriter.Save(myGrid);

将其加载到新对象中:

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