C#窗体跳转和隐藏原来的窗体

C#窗体如何从Form1跳转到Form2，同时隐藏Form1，关闭Form2时显示Form1

Form1，Form2的代码如下

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Visible = false;
            Form2 f = new Form2(this);
            f.Visible = true;
        }
    }

    public partial class Form2 : Form
    {
        public static Form2 frm2;
        private Form1 returnForm1 = null;
        public Form2(Form1 F1)
        {
            InitializeComponent();
            this.returnForm1 = F1;
            frm2 = this;
        }
        private void button2_Click(object sender, EventArgs e)
        {
            this.Close();
            this.returnForm1.Visible = true;
        }
    }
