SQL语句中的实体框架对象

[英]Entity Framework objects from SQL Statement

原文 2015-02-19 21:53:59 9 1 c#/ sql/ entity-framework/ datawindow

I've been working on a project which is based on PowerBuilder and DataWindow objects. 我一直在研究基于PowerBuilder和DataWindow对象的项目。 Now, one of the things we want is to "grab" the DataWindow objects and convert them to .NET objects (in C#) by basing them on the query. 现在，我们想要做的一件事情是“抓取” DataWindow对象，并根据查询将它们转换为.NET对象（在C＃中）。 From that query I want EF to analyse it and build an object that mirrors the object retrieved by that query/datawindow. 从该查询中，我希望EF对其进行分析并构建一个对象，该对象反映该查询/数据窗口检索到的对象。 The data is pulled from 4 different tables on a Sybase ASE database. 数据是从Sybase ASE数据库的4个不同表中提取的。

I was under the impression that I could tell EF to behave like that by passing it the query and letting it build the object but I've been unable do to so and I've sort of hit a brick wall since DataWindow.NET (from Sybase) is a discontinued project (in 2008) and I really can't find any other alternative besides EF. 我的印象是我可以通过向EF传递查询并让它构建对象来告诉EF那样的行为，但是我一直无法做到这一点，而且自从DataWindow.NET（ Sybase）是一个已停产的项目（在2008年），除EF外，我真的找不到其他选择。

If the intended behavior is possible, could someone point me in the right direction? 如果可能的行为是可能的，那么有人可以向我指出正确的方向吗？ And if not, is there any component/framework that behaves like intended? 如果不是，是否有任何组件/框架的行为像预期的那样？

Entity Framework doesn't work this way. 实体框架无法以这种方式工作。 You can't give it some SQL and have it hydrate some .NET objects for you. 您不能给它一些SQL并为它添加一些.NET对象。 You can however do this using Dapper-dot-net . 但是，您可以使用Dapper-dot-net进行此操作。
