I have this line of code but i get a null reference when i run the code. I need to ..for example, say if it's null..replace with a default value or leave can I do this?

if (null == item.Shipment.CreatedOn)
{cmd.Parameters.Add("@ShipDate", SqlDbType.DateTime).Value = "defaultvalue";}
{cmd.Parameters.Add("@ShipDate", SqlDbType.DateTime).Value = item.Shipment.CreatedOn;}

thanks, let me try
Equivalent, in one line:

cmd.Parameters.Add("@ShipDate", SqlDbType.DateTime).Value = (item.Shipment.CreatedOn == null) ? "defaultvalue" :  item.Shipment.CreatedOn;

You might not find it as readable, but just to offer an alternative.

that's like the IIF in, i think. Let me try.
CamilliaAuthor Commented:
DBNull.Value for "defaultvalue"?
no for the null check
with minor change depending if Nulls allowed in DB Field
cmd.Parameters.Add("@ShipDate", SqlDbType.DateTime).Value = (item.Shipment.CreatedOn == null)  ? (object)DBNull.Value : item.Shipment.CreatedOn;
