A local variable named 'p' cannot be declared in this scope because it would give a different meaning to 'p', which is already used in a 'parent or current' scope to denote something else

Hello,

C#

foreach (SqlParameter parameter in commandParameters) {
        // check for derived output value with no value assigned
        if (((parameter.Direction == ParameterDirection.InputOutput) && (parameter.Value == null))) {
            parameter.Value = null;
        }
        command.Parameters.Add(parameter);
    }

and remove:

SqlParameter p = default(SqlParameter);

Valery.
