cannot convert from 'System.Guid?' to 'System.Guid'

Question

Does anyone know how to deal with this error?

cannot convert from \'System.Guid?\' to \'System.Guid\'

Answer 1

First intialize the guid variable.

Guid yourGuid= Guid.NewGuid()

then set value in that which you want for eg:

 Guid defaultId = Guid.NewGuid();
 if (customerRow.GuardianState.Length > 2) {
 Guid StateId = record.StateId ?? defaultId;}
