推荐答案

文本到网页，然后使浏览器提高输入框的更改/输入事件？您必须调用onChange事件或其他一些事件。

You're trying to input text to webpage then make make the webbrowser raise the change/input event of the input box? You have to invoke "onChange" event or some other event.

Bellow我使WebBrowser提高keydown事件，使用SendKey：

Bellow I make WebBrowser raise keydown event, use SendKey:

private void button2_Click(object sender, EventArgs e)
{
    HtmlDocument doc = webBrowser1.Document;
    HtmlElement HTMLControl2 = doc.GetElementById("flightno-filter");
    //HTMLControl.Style = "'display: none;'";
    if (HTMLControl2 != null)
    {
        // HTMLControl2.Style = "display: none";
        HTMLControl2.InnerText = textBox1.Text;

        HTMLControl2.Focus();              // Set focus to input box
        SendKeys.SendWait("{Right}");      // Send "Right" key
        textBox1.Focus();                  // Give focus back for one of WinForms control

    }
}
