public void CreateSqlParameter()
{
    SqlParameter parameter = new SqlParameter(
        "@Description", SqlDbType.VarChar);
    parameter.IsNullable = true;
    parameter.Direction = ParameterDirection.Output;
    parameter.SourceColumn = "Description";
}

Public Sub CreateSqlParameter()
    Dim parameter As New SqlParameter( _
        "@Description", SqlDbType.VarChar)
    parameter.IsNullable = True
    parameter.Direction = ParameterDirection.Output
    parameter.SourceColumn = "Description"
End Sub

Remarks

The link between the value of the IDataParameter and the DataTable may be bidirectional depending on the value of the Direction property.
