Only assignment, call, increment, decrement, and new object expressions can be used as a statement error when no error(Closed)

Question

Im getting these two errors, 1.Only assignment, call, increment, decrement, and new object expressions can be used as a statement 2.; Expected

 protected bool IsPatientAlreadyExists(String patientId)
    {
        using (CareGiverEntities dc = new CareGiverEntities())
        {

             dc.Contacts.Add(new Contact
            {
               return dc.Contacts.Any(x=> x.PatientIc==patientId);
            });
        }
        return false;

    }

i really cant see whats wrong with these codes hoping someone can enlighten me

It seems you copy/pasted something and did not clean up: guessing from your method's name, remove `dc.Contacts.Add(new Contact {` You only want to keep this line: `return dc.Contacts.Any(x => x.PatientId == patientId);` — René Vogt, Feb 06 '17 at 13:47
You can't use `dc.Contacts.Add(new Contact)` line with `return` keyword inside. — Saurabh Srivastava, Feb 06 '17 at 13:47
@galister what do you mean? Note that your answer is the same as my comment. — René Vogt, Feb 06 '17 at 13:48

The problem is here:

dc.Contacts.Add(new Contact
{
    return dc.Contacts.Any(x => x.PatientIc == patientId);
});

You create Contact object but use return statement in object initializer.

Change your using to:

using (CareGiverEntities dc = new CareGiverEntities())
{
    return dc.Contacts.Any(x => x.PatientIc == patientId);
}
