Your question have a ready answer here


So DataReader should throw an exception on null values being fetched.
The proper way of dealing with it is IsDBNull method, which is used by
MS.NET DataAdapter when it analyse result. GetValue () should probably
just return DBNull.Value, though I didn't test this.
