Unable to create a constant value of type <object>. Only primitive types or enumeration types are supported in this context - entity-framework

Question

I am using the following code:
public static Grid.GridResult GetExamDetailsForGrid(Grid.GridFilter Filter, int userid, int _user_roleid, int selectedYear,string Tin,string Measure, DateTime? Startdate, DateTime? Enddate)
{
Grid.GridResult _examsEntered = new Grid.GridResult();
using (var entity = new PQRSEntityContainer())
{
((IObjectContextAdapter)entity).ObjectContext.CommandTimeout = 120;
var Measureid = 0;
if(!string.IsNullOrEmpty(Measure))
{
Measureid = entity.tbl_Lookup_Measure.Where(m => m.CMSYear == selectedYear && m.Measure_num == Measure)
.Select(v => v.Measure_ID).FirstOrDefault();
}
var _username = CurrentUser.UserName;
var npi = FileProcessBL.getNPINumber(userid);
var cmsYear = selectedYear != 0 ? selectedYear : 0;
var Newtin= string.IsNullOrEmpty(Tin) ? null : Tin;
var NewStartdate = Startdate ==null ? null : Startdate;
var NewEnddate = Enddate == null ? null : Enddate;
var NewMes= string.IsNullOrEmpty(Measure) ? null : Measure;
var liDetails = (from ex in entity.tbl_Exam.Where(i => i.Physician_NPI == npi && i.CMS_Submission_Year == cmsYear
&& i.Exam_TIN == (Newtin==null?i.Exam_TIN:Newtin)
&& i.Exam_Date >= (NewStartdate == null ? i.Exam_Date : NewStartdate)
&& i.Exam_Date <= (NewEnddate == null ? i.Exam_Date : NewEnddate))
from exmes in entity.tbl_Exam_Measure_Data.Where(i => i.Exam_Id == ex.Exam_Id
&& i.Measure_ID== (Measureid == 0 ? i.Measure_ID : Measureid) ).DefaultIfEmpty()
from nume in entity.tbl_lookup_Numerator_Code.Where(nume => exmes.tbl_Lookup_Measure.Measure_ID == nume.tbl_Lookup_Measure.Measure_ID && exmes.Numerator_response_value == nume.Numerator_response_Value).DefaultIfEmpty()
join sc in entity.tbl_Lookup_Data_Source on ex.DataSource_Id equals sc.DataSource_Id
where exmes.Exam_Id != null
select new MesCasesGrid
{
NPI = ex.Physician_NPI,
TIN = ex.Exam_TIN == null ? "" : ex.Exam_TIN,
ExamID = ex.Exam_Id,
//MeasureID = exMes.Measure_ID,
MeasureID = (exmes != null) ? exmes.Measure_ID : 0,
MeasureNum = (exmes != null) ? exmes.tbl_Lookup_Measure.Measure_num : null,
CPTCode = (exmes != null) ? exmes.Denominator_proc_code : null,
///NumeratorCode = (exmes!=null)?exmes.tbl_Lookup_Measure.tbl_lookup_Numerator_Code.Select(i=>i.Numerator_Code).FirstOrDefault():null,
NumeratorCode = nume.Numerator_Code,
Created_Date = ex.Created_Date,
ExamDate = ex.Exam_Date,
UniqueExamID = ex.Exam_Unique_ID,
PatientGender = (ex.Patient_Gender == "M" ? "Male" : ex.Patient_Gender == "F" ? "Female" : ex.Patient_Gender == "O" ? "Other" : ex.Patient_Gender == "U" ? "Unknown" : ""),
PatientID = ex.Patient_ID,
isEncrypt = ex.IsEncrypt,
PatientAge = ex.Patient_Age,
StatusDesc = (exmes != null) ? exmes.tbl_Lookup_Measure_Status.Status_Desc : null,
///Type =ex.DataSource,
Type = sc.DataSource,
cmsYear = ex.CMS_Submission_Year
}).Distinct().ToList();
if (_user_roleid == Constants.FacilityAdminID || _user_roleid == Constants.FacilityUserID || _user_roleid == Constants.RegistryAdminID
|| _user_roleid == Constants.SuperCorporateAdminID || _user_roleid == Constants.CorporateAdminID || _user_roleid == Constants.ServiceUserID) // jira-579
{
var facilityTins = entity.sp_getFacilityTIN(_username).Select(x => x.TIN).ToList();
liDetails = liDetails.Where(i => facilityTins.Contains(i.TIN)).Select(x => x).Distinct().ToList();
}
var value = Convert.ToBoolean(1);
foreach (var item in liDetails)
{
if (item.isEncrypt == value && item.PatientID != null)
{
try
{
var patidDecrypt = AesHelper.Decrypt256(item.PatientID);
item.PatientID = patidDecrypt;
}
catch (Exception ex)
{
}
}
}
return _examsEntered;
}
}
I have recently added the following code above method:
i.Measure_ID == && i.Measure_ID== (Measureid == 0 ? i.Measure_ID : Measureid)
When adding the highlighted code to this method I am getting following error:
:Error in RecordEnteredGridBind()
System.NotSupportedException: Unable to create a constant value of type 'DAL.Entities.tbl_Exam_Measure_Data'. Only primitive types or enumeration types are supported in this context.

I have tried lot of ways but not working. So, Can anyone help me?
