如何克隆WPF对象？

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

public static T CloneObject<T>(T obj)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter formatter = new BinaryFormatter();
        formatter.Serialize(ms, obj);

        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}
