我编写了一个UIElement
复制元素的属性和子元素的扩展——请注意,它不会为克隆设置事件。

namespace UIElementClone
{
public static class UIElementExtensions
{
public static T DeepClone<T>(this T source) where T : UIElement
{
T result;
// Get the type
Type type = source.GetType();
// Create an instance
result = Activator.CreateInstance(type) as T;
CopyProperties<T>(source, result, type);
DeepCopyChildren<T>(source, result);
return result;
}
private static void DeepCopyChildren<T>(T source, T result) where T : UIElement
{
// Deep copy children.
Panel sourcePanel = source as Panel;
if (sourcePanel != null)
{
Panel resultPanel = result as Panel;
if (resultPanel != null)
{
foreach (UIElement child in sourcePanel.Children)
{
// RECURSION!
UIElement childClone = DeepClone(child);
resultPanel.Children.Add(childClone);
}
}
}
}
private static void CopyProperties<T>(T source, T result, Type type) where T : UIElement
{
// Copy all properties.
IEnumerable<PropertyInfo> properties = type.GetRuntimeProperties();
foreach (var property in properties)
{
if (property.Name != "Name") // do not copy names or we cannot add the clone to the same parent as the original.
{
if ((property.CanWrite) && (property.CanRead))
{
object sourceProperty = property.GetValue(source);
UIElement element = sourceProperty as UIElement;
if (element != null)
{
UIElement propertyClone = element.DeepClone();
property.SetValue(result, propertyClone);
}
else
{
try
{
property.SetValue(result, sourceProperty);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
}
}
}
}
}
}
