could not be set to a 'System.Decimal' value. You must set this property to a non-null value of type 'System.Double'
I think it might be because of null value conversion attempt to be stored in double.
Change your double to
double?For explanation, please see the link below:http://msdn.microsoft.com/en-us/library/2cf62fcy.aspx
Thanks!
It may be the problem from DB ,from my experience I got this exception because I use data from store-procedure (generate object class using entity framework)
that one number field in my SP I supplying a data contract like this
CAST(NULL AS DECIMAL) AS UnitAmountso in my code(after entity framework generate class) I got class that contain
Decimal UnitAmount{get;set;}but when I run my code this error happen
...could not be set to a 'System.Int32' value. You must set this property to a non-null value of type 'System.Decimal'.
it's because in my SP there is one case condition that I return my result like this so the data type return is mismatch.
-- if no dataSelect ... , 0 as UnitAmount, ....If you don't cast/convert the result 0 ->it will be seen as Int32 (0.00-> seen as Decimal ,)
