I'm coding a date class and am having trouble with the post-fix increment (the prefix increment seems fine).

Here is the sample code:

public class date
{
    int year,
        month,
        day;

    public date(int d, int m, int y)
    {
        day = d;
        month = m;
        year = y;
    }

    static public date operator ++(date d)
    { 
        return d.Next(d);
    }
}

The method "Next(date d)" takes a date and returns tomorrows date (I left it out for brevity). I'm to young in C# to understand why the prefix is fine but postfix increment does nothing. But remember in C++ we would have to have two methods instead of just one - for prefix and postfix increments.

Also no errors or warnings on compile.
