C#如何打印包含文本框和数值的列表？

Console.WriteLine("姓名：张三");
Console.WriteLine("年龄：25");

listBox1.Items.Add("姓名：" + textBox1.Text);
listBox1.Items.Add("年龄：" + textBox2.Text);

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
{
    Font font = new Font("Arial", 12);
    float lineHeight = font.GetHeight(e.Graphics);
    float x = e.MarginBounds.Left;
    float y = e.MarginBounds.Top;

    e.Graphics.DrawString("姓名：" + textBox1.Text, font, Brushes.Black, x, y);
    y += lineHeight;
    e.Graphics.DrawString("年龄：" + textBox2.Text, font, Brushes.Black, x, y);
}

private void button1_Click(object sender, EventArgs e)
{
    PrintDocument pd = new PrintDocument();
    pd.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
    pd.Print();
}
