的XmlSerializer 可能不精彩与关联。如果启用序列化的数据上下文的表面，它增加（WCF）数据契约属性。也许只需使用：

XmlSerializer may not be wonderful with associations. If you enable serialization on the data-context surface, it adds (WCF) data-contract attributes. Perhaps just use:

var data = db.MyEntitys.ToList();
var ser = new DataContractSerializer(data.GetType());
ser.WriteObject(dest, data);
