推荐答案
自跟踪实体是可序列化的，因此获取实体的深层克隆(deep clone =图形的克隆)的最简单方法是使用DataContractSerializer并序列化并立即反序列化.反序列化的实体将是您的图形克隆.
Self tracking entities are serializable so the simplest way to get deep clone of the entity (deep clone = clone of the graph) is to use DataContractSerializer and serialize and immediately deserialize it. Deserialized entity will be your clone of the graph.
