如何使用Linq与城堡的ActiveRecord [英] How to use Linq with Castle ActiveRecord

问题描述

我与城堡ActiveRecord的玩耍，发现下载包含的文件， Castle.ActiveRecord.Linq.dll 。我还没有发现任何文档使用LINQ用ActiveRecord，只有一些的old 的blog帖子的。

I am playing around with Castle ActiveRecord and noticed that the download included the file, Castle.ActiveRecord.Linq.dll. I haven't found any documentation for using Linq with ActiveRecord, only some old blog posts.

什么是使用模式？为 Castle.ActiveRecord.Linq 可供生产使用？

What is the usage pattern? Is Castle.ActiveRecord.Linq ready for production use?

推荐答案

是的，Castle.ActiveRecord.Linq是生产准备就绪。它是包含在最新的ActiveRecord版本。实际的LINQ提供程序是NHibernate.Linq.dll实施，ActiveRecord的LINQ的DLL是薄直通层。有使用它基本上有两种方式：

Yes, Castle.ActiveRecord.Linq is production ready. It's included in the latest ActiveRecord release. The actual Linq provider is implemented in NHibernate.Linq.dll, the ActiveRecord Linq dll is a thin pass-through layer. There are basically two ways to use it:

1. 请您实体从 ActiveRecordLinqBase<继承; T> ，然后查询：

var blogs = (from b in Blog.Queryable select b).ToList();

使用 ActiveRecordLinq.AsQueryable< T> ，例如：

var blogs = (from b in ActiveRecordLinq.AsQueryable<Blog>() select b).ToList();

看的测试了解一些示例代码

更新：为ActiveRecord的3.0测试版中的LINQ集成到Castle.ActiveRecord.dll和NHibernate.Linq.dll没有更多的（融入NHibernate.dll例如NHibernate 3）

UPDATE: as of ActiveRecord 3.0 beta, Linq is integrated into Castle.ActiveRecord.dll, and NHibernate.Linq.dll is no more (integrated into NHibernate.dll as of NHibernate 3)
