以下详细说明了我收到的错误 The Student Class

public class Student () {
    public int Id {get;set;}
    public Student(int id IEnumerable<StudentOwner> owner) {
         _owners = owners != null ? owners.ToList() : new List<StudentOwner>();
    }
    private List<StudentOwner> _owners;
}

StudentDetails 类

public class StudentDetails () {
    pubiic int Id {get; set;}
    public DateTime UpdateDate { get; }
    public string Comments { get; set; }
    public int StudentRef {get; set; }

}

查询的违规代码选择如下，如果你按 s.ID 订购，则可以使用

  baseQuery = baseQuery.Where(
              o => s.StudentDetails
                   .OrderByDescending(s => **s.UpdateDate**).First().StudentRef
                == StudentSearchParams.StudentRef;

发生以下错误，但是如果你按 Id 进行排序，它可以工作，但不会产生所需的结果。有任何想法吗 ？？？

 .OrderByDescending(s1 => s1.UpdateDate)' could not be translated. 
 Additional information: Translation of member 'UpdateDate' on entity type 'StudentDetails' failed. 
 This commonly occurs when the specified member is unmapped. Either rewrite the query in a form 
 that can be translated, or switch to client evaluation explicitly by inserting a call to 
 'AsEnumerable', 'AsAsyncEnumerable', 'ToList', or 'ToListAsync'. See https://go.microsoft.com/fwlink/?linkid=2101038 for more information.
