Linq To SQL:类型为'；System.OutOfMemoryException'；被抛出，如何更正
本文关键字：何更正 OutOfMemoryException System 类型 SQL To Linq | 更新日期: 2023-09-27 18:24:12
我正试图用Linq从服务器检索数据，这个表中大约有167条记录，但当我编译代码时，我总是收到这个错误：
Exception of type 'System.OutOfMemoryException' was thrown .
在这里，我发布了我使用的代码（使用LinqPad）：

你知道这一步怎么走吗？
非常感谢您的关注。
干杯
在上次查询中使用query1和query2之前，为什么不使用ToList()方法来解决您的问题。。。。。
var query1 = (from dad in data select d ).ToList();
