I want to update label of Form1 from Form2. So here's what I have:

// Form1
public string Label1
{
    get { return this.label1.Text; }
    set { this.label1.Text = value; }
}


// Form2
private void button1_Click(object sender, EventArgs e)
{
    Form1 frm1 = new Form1();
    frm1.Label1 = this.textBox1.Text;
    this.Close();
}

So the above code doesn't work. However, when I add the following:

frm1.Show();

after

this.Close();

in Form2 code, the Form1 is being opened again (two windows). But I want it to update in the same window so I suggest this.Close() is unnecessary.
