{
db.SaveChanges();
}
catch (DbEntityValidationException dbEx)
{
foreach (
var validationErrors
in dbEx.EntityValidationErrors)
{
foreach (
var validationError
in validationErrors.ValidationErrors)
{
Trace.TraceInformation("Property: {0} Error: {1}",
validationError.PropertyName,
validationError.ErrorMessage);
}
}
}
Using debug tools, set breakpoints, then you will see the detail error message during the foreach loop.
