It gives the following error after i used this coding

int iNewOitem = dc.tOrderDetails.Max(u => u.OrderItemId ?? 0) + 1;

Operator ‘??’ cannot be applied to operands of type ‘int’ and ‘int’

Kindly give me a solution.

int iNewOitem = dc.tOrderDetails.Max(u => u.OrderItemId ?? 0)+ 1;

int iNewOitem = dc.tOrderDetails.Max(u => u.OrderItemId)+ 1;

Objective : if the database value is null ” dc.tOrderDetails.Max(u => u.OrderItemId) ” should return the value “0″ else it may return the exact maximum value .

how is it possible ? hope u can understand ?
