用webBrowser模拟点击页面

自动输入内容并提交

            this.tb_url.Text = "http://www.baidu.com";
            this.webBrowser1.Url = new Uri(this.tb_url.Text.Trim());
            HtmlElement kw = webBrowser1.Document.All["kw"];
            HtmlElement su = webBrowser1.Document.All["su"];
            string str = DateTime.Now.ToString();
            str = "百度知道";
            kw.SetAttribute("value", str);
            su.InvokeMember("click");

 

模拟点击页面中的链接

            HtmlElementCollection link = webBrowser1.Document.GetElementsByTagName("a");
            for (int i = 0; i < link.Count; i++)
            {
                if (link[i].InnerHtml != null)
                {
                    if (link[i].InnerHtml.IndexOf("百度") != -1) //带百度2个字的链接会被点击
                    {
                        link[i].InvokeMember("click");
                        break;
                    }
                }
            }
