Answer 1

.Show()将显示您正在显示的新表单，但它将使您能够返回并使用主表单中的控件， .ShowDialog()不允许您访问主表单，除非将其关闭。

f2.ShowDialog();

Answer 2

Try using

Form2 f2 = new Form2();
f2.showDialog();

Answer 3

I tested that ways and don't worked but only below code worked:

    private void button1_Click_1(object sender, EventArgs e)
    {
        Form2 frm = new Form2();
        this.Enabled = false;
        frm.Show();
        frm.FormClosing += new FormClosingEventHandler(frm_FormClosing);
        frm.Show();
    }

    private void frm_FormClosing(object sender, FormClosingEventArgs e)
    {
        this.Enabled = true;
    }
