c#静态扩展方法，字典的克隆扩展方法
这种方法是采用序列化反序列的克隆，是最靠谱的克隆，同样这种写法可以应用到类克隆，List克隆，都可以

原方法：可*修改
public static T Clone<T>(T RealObject)
{
using (Stream objectStream = new MemoryStream())
{
//利用 System.Runtime.Serialization序列化与反序列化完成引用对象的复制
IFormatter formatter = new BinaryFormatter();
formatter.Serialize(objectStream, RealObject);
objectStream.Seek(, SeekOrigin.Begin);
return (T)formatter.Deserialize(objectStream);
}
}
