大家好日子 .
我有实体或复杂类型无法遇到这是我第一次遇到这种类型的错误有人帮我
public IEnumerable<APPLICANT> GetApplicant()
{
IEnumerable<APPLICANT> applicantdata = Cache.Get("applicants") as IEnumerable<APPLICANT>;
IEnumerable<Profile> profiledata = Cache.Get("profiles") as IEnumerable<Profile>;
if (applicantdata == null)
{
var applicantList = (from a in context.Profiles
join app in context.APPLICANTs
on a.PROFILE_ID equals app.Profile_id
where app.APPLICANT_LogicalDelete == false
select new APPLICANT()
{
APPLICANT_LastName = a.Applicant_LASTNAME,
APPLICANT_FirstName = a.Applicant_FIRSTNAME,
APPLICANT_MiddleName = a.Applicant_MIDDLENAME,
APPLICANT_Address = a.Applicant_ADDRESS,
APPLICANT_City = a.Applicant_CITY,
APPLICANT_Phone = a.Applicant_PHONE,
APPLICANT_Email= a.Applicant_EMAIL
});
applicantdata = applicantList.Where(v => !String.IsNullOrEmpty(v.APPLICANT_LastName)).OrderBy(v => v.APPLICANT_ID).ToList();
if (applicantdata.Any())
{
Cache.Set("applicants", applicantdata, 30);
}
}
return applicantdata.ToList().Take(1000);
}
这是我遇到错误的行谢谢！
applicantdata = applicantList.Where(v => !String.IsNullOrEmpty(v.APPLICANT_LastName)).OrderBy(v => v.APPLICANT_ID).ToList();
和上面的线路中的错误是
System.NotSupportedException：无法在LINQ to Entities查询中构造实体或复杂类型“Model.APPLICANT” .
