winform 多窗体相互切换form

    public partial class FrmSideBar : Form
    {
        private Form1 mainForm = null;
        public FrmSideBar(IntPtr frmPtr)
        {
            InitializeComponent();
            this.mainForm = (Form1)Form1.FromHandle(frmPtr);

            int Y = Screen.PrimaryScreen.Bounds.Height- this.Height- ;
            int X = Screen.PrimaryScreen.Bounds.Width - this.Width;

            this.Location = new Point(X,Y);
        }
}

            Program.frmSideBar = new FrmSideBar(this.Handle);
            Program.frmSideBar.ShowDialog();

    static class Program
