WCF，序列化大量数据时内存不足异常

基本上，我从SQL Server中获取数据。如果我选择所有的数据（这大约是80000行），然后我收到以下错误（接收100行工作正常）

似乎很简单：“没有足够的内存来继续执行程序时引发的异常”http://msdn.microsoft.com/en-us/library/system.outofmemoryexception.aspx –

@ DaveZiegler感谢您的回应！我知道我有一个内存管理问题。我的问题是，我该如何解决这个问题。 – Adrian

那么，你返回多少数据？有多少内存可用？我不认为这是你可以在web.config中修复的东西。你能带回更少的数据吗？或者你需要一次全部80000+行？ –

如果你从你的服务返回80K行话，我想你最好摆脱服务的都在一起。只需让客户端直接访问数据库，然后他们就可以从数据库中提取所需的所有行。

编辑

介绍服务边界，它没有必要是一个非常常见的错误，和一个我看到的情况越来越多。在大多数情况下，让客户端直接使用NHibernate甚至ADO以及存储过程或视图来调用数据库会更清晰。

如果您的客户端无法在物理上看到网络上的数据库，那么您可能必须使用服务。

感谢您的回应！你能否提供一些例子？我对“一起摆脱所有服务的含义感到困惑，只是让客户端直接访问数据库”...我想保持我的客户端清洁.. – Adrian
