i have tried

foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("select"))
{
if (el.Id == "DDL1")
{
foreach (HtmlElement comboItem in el.Children)
{
comboBox1.Items.Add(comboItem.InnerText);
if (comboItem.InnerText == "select from list")
{
comboBox1.SelectedItem = comboItem.InnerText;
}

}
}
}
