Nullable object must have a value.
I have a variable defined as an int and then assign it a value of 0. Next I read a field of data from a table and determine if it is null or has a value. If it has a value I assigne it to the variable. I keep getting this error message even after I initialze the variable with 0. What am I missing?
Here is the code:
Here is the code:
class Program
{
// Global Variables Class
internal static class MyGlobalVars
{
public static int docnpi;
public static Guid initGuid;
}
static void Main(string[] args)
{
MyGlobalVars.docnpi = 0;---------------------------- Variable Initilized HERE -------
DataClasses1DataContext dcChartRelay = new DataClasses1DataContext();
DataClasses2DataContext dceClinicalWorks = new DataClasses2DataContext();
// Query to get all patients from the Patients table
// that have not been flagged as imported
var patients = from p in dceClinicalWorks.patients
where p.Imported == null
join d in dceClinicalWorks.doctors on p.doctorId equals d.doctorID
join u in dceClinicalWorks.users on p.pid equals u.uid
join i in dceClinicalWorks.patientinfos on p.pid equals i.pid
select new { d, u, i, p };
// Process each row of the result set in the foreach loop
foreach (var patient in patients)
{
// ------- eClinical Tables
patientinfo myPatientInfo = new patientinfo();
user myUser = new user();
// ------- Chart Relay Tables
MPI myMPI = new MPI();
PATIENT myCRpatient = new PATIENT();
PATIENT_PHONE_NUMBER myPatPhones = new PATIENT_PHONE_NUMBER();
Patient_Address myPatAddresses = new Patient_Address();
PATIENTS_ATTENDED_BY_DOCTOR myPatAttByDoc = new PATIENTS_ATTENDED_BY_DOCTOR();
PATIENT_IN myPatIns = new PATIENT_IN();
EMPLOYER myPatEmployers = new EMPLOYER();
BillingAlert myPatBillAlerts = new BillingAlert();
EligibilityStatus myPatElgStatus = new EligibilityStatus();
// ----------------Write the MPI Record
MyGlobalVars.initGuid = Guid.NewGuid();
myMPI.MPI1 = MyGlobalVars.initGuid;
//myMPI.NPI = Convert.ToInt32(patient.d.NPI.ToString());
MyGlobalVars.docnpi = patient.d.NPI != null ? (int)myMPI.NPI : 0;----- ERROR HERE-----------------------------------

weelio,
Thank you very much.
Thank you very much.
Hi Kenny;
Not sure on this but try this.
Change this line of code in the MyGlobalVars class:
public static int docnpi;
to this:
public static int? docnpi;
Change this line at the end of the code:
MyGlobalVars.docnpi = patient.d.NPI != null ? (int)myMPI.NPI : 0;
To this:
MyGlobalVars.docnpi = patient.d.NPI.GetValueOrDe fault();
