C# webBrowser 類比登陸填充操作等(寫網頁註冊機之類的時候要用到)

判斷是否網路正常private   bool IsConnectedToInternet(){    int Desc;    return internet.InternetGetConnectedState(out   Desc, 0);}   設定預設頁面:webBrowser1.Navigate(new Uri("http://www.ic2ic.com/copy.jsp"));登入代碼: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");//這是登入成功的操作,跳轉到//upload.asp      //注意不是直接跳過去的,類比點選連結      //SESSION不會丟失      herfclick("http://www.ic2ic.com/copy.jsp");} 類比點選連結: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");//引發”CLICK”事件                 break;        }    }}運行網頁中的JS函數private void callJsMethod(string jsfun,string jsParameter)//函數名字,函數參數{         HtmlDocument doc = webBrowser1.Document;         doc.InvokeScript(jsfun,new object[]...{jsParameter});}填充資料: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");//選擇radio控制項      txtarea[0].InnerText = txt.ToString();}原理很簡單,在webBrowser1的DocumentCompleted事件中判斷一下當前完成的url地址,如果當前完成url和當初要開啟的url相等,就確定當前網頁已經載入完成 //string strURL 要找開的頁面的URL
        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            if (e.Url.ToString().Trim() == strURL.Trim())
            {
                //已經載入完成
            }       }控制流程動條webBrowser1.Document.Window.ScrollTo(100, 100);//滾動到你要的座標,以像素為單位
