我对 .NET 还很陌生，但是现在已经在这个项目上工作了一段时间，进展甚微，而且随着课程数量的增加，它变得有点不堪重负。
客观的：
从实体框架表生成数据（应该使用 LINQ）<- LINQ 似乎正在工作。
将数据转换为 XML <-根本不工作
如果不工作，则发送电子邮件<-这工作得很好，很奇怪，哈哈；）
谁能给我一个代码示例，您可以在其中通过 DataContract 连接到实体并序列化（如果这是最好的方法，可能使用泛型）到 XML Writer？根据这里的评论是我想要的一个样本。-- 所以我们还说，在这个模型中，我们想要加入“DIRTYMIKE”表，其中包括“男孩”作为一个对象，其名称将通过 xml 和 PRIUS 中的“CARS”表通过 id 提取显然这是一个理论上的实体集，但希望它能给某人带来笑声:)
这是我刚刚开始的一些理论课-希望这能更多地解释目标是什么：

//Really I am supposed to use LINQ for the querying
