实现效果:
  

知识运用:
  RegistryKey类的GetValue方法

  public Object GetValue (string name , Object defaultValue)

  name : 要检索的值的名称

  defaultValue: 在name不存在时返回的值 

实现代码:

        private void Form1_Load(object sender, EventArgs e)
        {
            RegistryKey regMain = Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Internet Explorer\Main");
            object DPage = regMain.GetValue("Start Page","没有值");
            textBox1.Text = DPage.ToString();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            if (!string.IsNullOrEmpty(textBox2.Text))
            {
                RegistryKey regMain = Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Internet Explorer\Main");
                regMain.SetValue("Start Page", textBox2.Text);
                MessageBox.Show("已设置主页为:"+textBox2.Text);
            }
        }
        private void button2_Click(object sender, EventArgs e)
        {
            RegistryKey regMain = Registry.CurrentUser.CreateSubKey(@"Software\Microsoft\Internet Explorer\Main");
            regMain.SetValue("Start Page", "about:blank");
            MessageBox.Show("已设置主页为:"+"空白页");
        }
