克隆WPF控件和对象层次结构

Question

我有一些问题克隆一个对象hierarchie.它是用于建模应用程序的工具包,工具箱包含类实例作为原型.但是我很难克隆这些:)

以下代码显示了问题:

public abstract class Shape {
  protected List<UIElement> elements;
  private Canvas canvas;
  ...
  public Canvas getCanvas() { ... };
}

public class MovableShape : Shape {
  protected ... propertyA;
  private ... propertyXY;
  ...
}

public abstract class AbstractLayout : MovableShape, ... {
  ...
}

public class SomeLayoutClass : AbstractLayout, ... {
  ...
}

public class AContainingClass {
  SomeLayoutClass Layout { get; set; }
  ...
}

当我将一个对象插入AContainingClass到我的项目工作表中时,它应该被克隆.到目前为止,我尝试了手动克隆(由于private基类中的字段而失败)和二进制序列化(BinaryFormatter和MemoryStreams).

第一种方法缺乏调用base.clone()方法的方法(或者我错了？),后者不起作用,因为UIElements不是[Serializable].

注意:它必须是深拷贝!

有任何想法吗？谢谢!

UPDATE

只是为了澄清我的手动克隆方法:如果每个类都有自己的Clone方法,那么如何调用Clone基类的方法？

public class Shape { // not abstract any more
  ...
  public Shape Clone() {
    Shape clone = new Shape() { PropertyA = this.PropertyA, ... };
    ...do some XamlWriter things to clone UIElements...
    return clone;
  }
}

public class MovableShape : Shape {
  ...
  public MovableShape Clone() {
     // how to call base.Clone??? 
     // this would be required because I have no access to the private fields!
  }
}

Answer 1

这里有它的功能:

    public T XamlClone<T>(T source)
    {
        string savedObject = System.Windows.Markup.XamlWriter.Save(source);

        // Load the XamlObject
        StringReader stringReader = new StringReader(savedObject);
        System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
        T target = (T)System.Windows.Markup.XamlReader.Load(xmlReader);

        return target;
    }
