相关疑难解决方法(0)

采访者今天问我这件事......有答案吗？

我有这样的代码:

var myList = db.Table1.ToList();
/*doing some operations on the list*/
var myList = db.Table2.ToList();
/*again doing some operations on the list*/
var myList = db.Table3.ToList(); // I'm getting out of memory exception here.

我不能按页检索数据,因为我需要一次所有的表.在加载另一个表之前,如何处理(我的意思是释放该列表所公开的空间)列表？谢谢.

编辑:

我加载后,实际上是从myList生成了很多(有时是数千个)子列表.所以我真的需要学习如何释放列表.
