Question

I have one form and a button inside it, how can i toggle the window height, so when i click on the button for the first time, the window height will increase by 166, and when i click on the button for the second time, the height will be decreased by 166.

Sorry for the question being stupid but i got really confused ;thanks

 private void button2_Click(object sender, EventArgs e)
    {

        int  FormHeight = this.Height;
        int  FormHeightBefore = FormHeight;

        if (this.Height == FormHeightBefore)
        {//toggle off 
            this.Height = this.Height + 166;
        }
        else { 
        //toggle on
            this.Height = this.Height - 166;
        }

    }

I tried with the code above but the it doesn’t worked, Whenever i press the button, the form height still increasing

partial class Form1 {
    public int FormHeight;

    private void button2_Click(object sender, EventArgs e) {
        this.Height += (FormHeight = (FormHeight > 0 ? -1 : 1) * 166);
    }
}
