Ray*_*eng 2 c# oracle orm entity-framework
Oracle 的实体框架支持使所有类名都大写并保留下划线。因此 ORDER_ITEMS 表在类名中变为 ORDER_ITEMS。但我想使用帕斯卡大小写作为类名。
ORDER_ITEMS ==> 需要 OrderItems。
如何更改默认命名规则？

大约两周前，我的任务是摆脱 Linq Connect 作为我们的数据提供者，转而使用 EF 进行 ORM 操作。众所周知，当微软和甲骨文参与其中时，事情绝非易事，因为它们不能很好地协同工作。精明的开发人员需要找到 Pascal 大小写和复数化的解决方案，以便从 Oracle 数据库生成的实体符合我们的标准。我们不希望带下划线的表名出现在我们的模型上。经过一番思考和开发，最终得出了一个好的解决方案。最终结果是操作 EDMX 文件，然后运行 T4 模板来实现奇迹。我们的最终结果将所有实体及其属性转换为帕斯卡大小写。它还将所有存储的函数转换为 Pascal 大小写。集合的导航属性也全部是复数的。以下是要遵循的步骤和代码片段。希望这对编码社区中的某些人有所帮助，您可以随时通过 Twitter 上的seafarer_007 与我联系，提出有用的评论或建议。如下： 1. 使用 EF 数据模型项生成 EDMX。我在 Visual Studio 2012 中使用了 EF 5.0。 2. 编写一个控制台应用程序来操作 EDMX 和设计器文件。我在应用程序配置中添加了对两者的引用。3. 应该就是这样，您将拥有 Pascal 大小写和复数实体。您可以随时根据自己的需要调整帕斯卡案例方法。4. 我在 Visual Studio 2012 和 EF 5.0 上测试了代码。5.警告：仅适用于不带点的单字命名空间，基本上您可以\xe2\x80\x99t为模型提供 OrgName.DeptName.Namespace，它只会处理 OrgName，但是，您可以调整 Pascal 大小写方法来解决那。
