推荐答案

像这样的实体使用AsEnumerable！

use AsEnumerable with the entity like this!

public IEnumerable<dml.person> GetAll()
        {
       
            var a = (from p in dbo.Person.AsEnumerable()
                     join r in dbo.Role.AsEnumerable() on p.PersonRoleID equals r.RoleID
                     select new DML.Person { 
                      Name =  p.Name,
                       Role= r.Name

                     });

           return a;

        }
</dml.person>

如果你搜索谷歌有很多例子这个问题被问到了。



这里甚至有一个：错误实体或复杂类型'EPatient.Models.cls_Measurement'不能在LINQ to Entities查询中构造。 [ ^ ]



也许你有同样的问题，解决方案同样适用于你。



鉴于有限我们可以看到的信息，无法访问您的解决方案，这是我能建议的最佳信息。

If you search google there is a whole host of examples of this question being asked.

There is even one on here: Error "The entity or complex type 'EPatient.Models.cls_Measurement' cannot be constructed in a LINQ to Entities query."[^]

Maybe you have the same problem and the solution equally applies to you.

Given the limited information we can see, and having no access to your solution, that is the best I can suggest.
