When communicating with a database use DBNull to indicate that the value of the column should be null (or Nothing in VB).

The reason for this is that there is to distinguish two different types of nullness. For example if you have a query and use ExecuteScalar to get a result you need to distinguish between Nothing (or null in C#) and DBNull. Nothing means that your query return no results. DBNull means that the query returned a result, and that result was null. (i.e. the value of the column was null).
