Im calling a SQL stored procedure from a piece of C#.net code:

Answer 1

You can pass the DBNull.Value into the parameter's .Value property:

    SqlParameters[0] = new SqlParameter("LedgerID", SqlDbType.BigInt );
    SqlParameters[0].Value = DBNull.Value;

Just adjust for your two DateTime parameters, obviously - just showing how to use the DBNull.Value property value here.
