Question

我正在开发一个从网站上获取数据的项目。所以我使用webBrowser并将url设置为travelchi.ir并在下面编写代码

 private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            HtmlDocument doc = webBrowser1.Document;
            HtmlElement Source = doc.GetElementById("from");
            HtmlElement Destination = doc.GetElementById("to");
            HtmlElement adultCount = doc.GetElementById("adultCount");
            HtmlElement childCount = doc.GetElementById("childCount");
            HtmlElement infantCount = doc.GetElementById("infantCount");
            var links = webBrowser1.Document.GetElementsByTagName("button");
            var inputs = webBrowser1.Document.GetElementsByTagName("input");
            Source.SetAttribute("value", "شیراز");
            Destination.SetAttribute("value", "تهران");
            adultCount.SetAttribute("value", "1 بزرگسال");
            childCount.SetAttribute("value", "1 کودک");
            infantCount.SetAttribute("value", "0 خردسال");
            foreach (HtmlElement input in inputs)
            {
                if (input.GetAttribute("className") == "form-control")
                {
                    input.SetAttribute("value", "1395/05/14");
                }
            }

            foreach (HtmlElement link in links)
            {
                if (link.GetAttribute("className") == "btn btn-primary")
                {
                    link.InvokeMember("click");
                }
            }

到getelement并设置值，所以最后我知道这段代码不能设置值请帮我解决一下

方法 getElementById 而非 GetElementById 。

对于getElementsByTagName和setAttribute

也是如此
