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");
}
