Is there a way to handle a DataColumn returning DBNull in a single line statement?

I have a table returning a column defined at decimal(18,2).  This column is allowed to return a DBNull.  I am trying to eloquently handle the value in this column as I am using it just once in a method as part of an equation.  This scenario is repeated for about 15 more columns returned in this table.  Each column is capable of returning as DBNull and I need to be able to use (or convert for use) the DBNull as a decimal.

decimal.Parse(ds.Tables[0].Rows[0]["MyNullableColumn"].ToString())  will throw an exception when the data in the column is null.

Thanks,
Bruce

I suspect what you are after is the ternary operator:

ds.Tables[0].Rows[0]["MyNullableColumn"] == DBNull.Value ? 0M : Convert.ToDecimal(ds.Tables[0].Rows[0]["MyNullableColumn"])
