Question

我编写了以下用于生成报告的sql。我运行一些sql sueries并将其结果存储在临时表中，并在sproc的末尾将所有表联合起来。然而，当我将这个sproc添加到EF时，它不会为它创建一个复杂的类型，没有它就没用。如何使EF识别返回的结果集并创建复杂类型。

EF不会为您创建复杂类型，但EF可以实例化声明的复杂类型的对象集合。

例如

public class AType {
     public String Prop1 {get; set;}
}

context.Database.SqlQuery<AType>("select c1 as Prop1 from ATable");

将返回AType的集合。如果使用对存储过程的调用替换查询，则相同。

在这种情况下，您必须声明一个用于映射存储过程返回的类型。

否则你可以看看dynamic，但是：

不知道它是否适用于EF
您将失去使用编译语言的优势。

在使用dynamic进行一些测试后，会返回正确的数字或对象，但我对它们无能为力。

实体框架不会为我的存储过程创建复杂类型？
