How do I set the size of SqlParameter of SqlCommand for varchar(max)?

If you need to execute a Stored Procedure that implemented with varchar(max) parameter, using .Net Application, how do you set the size of the parameter?

Since the constructor of SqlParameter does not accept string value for size property, we have no way of passing max as the size;

// This will not compile
SqlParameter parameterNote = new SqlParameter("Note", SqlDbType.NVarChar, max);

But we can pass -1 as the size that indicates it is max;

SqlParameter parameterNote = new SqlParameter("Note", SqlDbType.NVarChar, -1);
