C# ,webBrowser,登录,数据填充,模拟点击链接,运行JS函数

判断是否网络正常

private   bool IsConnectedToInternet()

{

    int Desc;

    return internet.InternetGetConnectedState(out   Desc, 0);

}  

设置默认页面:

webBrowser1.Navigate(new Uri("http://www.ic2ic.com/copy.jsp"));

登录代码:

private void btnlogin_Click(object sender, EventArgs e)

{

     webBrowser1.Document.GetElementById("id").InnerText =txtuser.Text.ToString().Trim();//fill name

       webBrowser1.Document.GetElementById("passwd").InnerText =txtpwd.Text.ToString().Trim();//fill pwd

         HtmlElement formLogin = webBrowser1.Document.Forms["frmLogin"];

        formLogin.InvokeMember("submit");

        Thread.Sleep(5000);

        herfclick("http://www.ic2ic.com/upload.jsp");//这是登录成功的操作,跳转到//upload.asp

      //注意不是直接跳过去的,模拟点击链接

      //SESSION不会丢失

      herfclick("http://www.ic2ic.com/copy.jsp");

}

模拟点击链接:

private void herfclick(string url)

{

      for (int i = 0; i < webBrowser1.Document.All.Count; i++)

      {

          if (webBrowser1.Document.All[i].TagName == "A" && webBrowser1.Document.All[i].GetAttribute("href").ToString().Trim() ==url)

          {

                 webBrowser1.Document.All[i].InvokeMember("click");//引发”CLICK”事件

                 break;

        }

    }

}

运行网页中的JS函数

private void callJsMethod(string jsfun,string jsParameter)//函数名字,函数参数

{

         HtmlDocument doc = webBrowser1.Document;

         doc.InvokeScript(jsfun,new object[]...{jsParameter});

}

填充数据:

private void filldate(string txt)

{

       HtmlElement frmWord = webBrowser1.Document.Forms["frmWord"];//找到from

      HtmlElementCollection txtarea = frmWord.GetElementsByTagName("TEXTAREA");

       HtmlElementCollection radio = frmWord.GetElementsByTagName("INPUT");

       radio[2].InvokeMember("click");//选择radio控件

      txtarea[0].InnerText = txt.ToString();

}
