Question

I’m passing a bool to a method in another class by reference, so that I can change it (-the original argument) from within the method.

I also want an event (which is subscribed to by that method) to be able to change it.

Doing this:

class myCheckBox : CheckBox
{
    bool b1;
    public myCheckBox(ref bool b)
    {
        b1 = b;
        this.CheckedChanged += new EventHandler(myCheckBox_CheckedChanged);
    }

    void myCheckBox_CheckedChanged(object sender, EventArgs e)
    {
        b1 = Checked;
    }
}

doesn’t help, since b1 is only a copy of b.

Is there any way of doing: ref b1 = ref b; ? if not, how do I solve this?

(The examples are only to explain the question.)

Answer 1

Pass the class containing the field, a string denoting it, and save them instead of b1. Then use reflection.
