Whenever you think "there's common functionality!" you should consider a method to implement it. It could look like this:

    private void openFile(TextBox box) {
        if (openFileDialog1.ShowDialog(this) == DialogResult.OK) {
            box.Text = openFileDialog1.FileName;
            box.Focus();
        }
        else {
            box.Text = "";
        }
    }

    private void button1_Click(object sender, EventArgs e) {
        openFile(textBox1);
    }
