c#: force compiler blunder myobj.tostring()

i have category contains garland properties. mistake programmer tostring() an vigilant type. take instance code:

using system;

public category foo
{
    open int id = 123;
    open twine name = "somename";

    private twine tostring() { relapse null; }
}

public category myclass
{
    open stationary vacant main()
    {
        foo myobj = new foo();
        wl("i wish compiler error: {0}", myobj.tostring());
        rl();
    }

    #region supporter methods

    private stationary vacant wl(object text, params object[] args)
    {
        console.writeline(text.tostring(), args);   
    }

    private stationary vacant rl()
    {
        console.readline(); 
    }

    #endregion
}

you reason id many wish combined out string, following i should exercise tostring advantage id. however, i trust bad use since programmers "accidentally" operative code. programmer controlling category should mention want.

instead, i someone calls myobj.tostring() have arrangement adult accumulate error. i guess i formulating private tostring() function, nonetheless doesn't work.

the reason i brought adult finished adult query twine contained entirely competent category name rather following an id.

so doubt is: is there any proceed "hide" tostring() duty job an vigilant category causes compiler error?
