Answer 1

慢是正常的,你打开网页也需要时间啊?
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(Step1);
            webBrowser1.Navigate("http://www.ems.com.cn/");
        }        void Step1(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            WebBrowser wb = sender as WebBrowser;
            wb.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(Step1);
            wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(Step2);
            HtmlElement txt = webBrowser1.Document.All["mailNum"];
            txt.SetAttribute("value", "EC244752724CN");
            HtmlElement btn = webBrowser1.Document.All["btchaxun_r1_c2"];
            btn.InvokeMember("Click"); 
        }
        void Step2(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            WebBrowser wb = sender as WebBrowser;
            if (wb.Url.ToString().IndexOf("qcgzOutQueryAction.do") >-1) {
                wb.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(Step2);
                if (webBrowser1.Document.Body.InnerHtml.IndexOf(@"已妥投") > 0)
                {
                    MessageBox.Show("OK");
                }             }
        }
    }

Answer 2

为什么不直接webclient或者httpwebrequest？非得用WebBrowser么？

Answer 3

httpwebrequest想用这个可是不会啊

Answer 4

// 获取网页的HTML内容
static string GetPage(string url)
{
  HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
  try
  {
    using (HttpWebResponse res = (HttpWebResponse)req.GetResponse())
    {
      using (StreamReader sr = new StreamReader(res.GetResponseStream()))
      {
        return sr.ReadToEnd();
      }
    }
  }
  catch (System.Exception e)
  {
    return e.Message;
  }
  finally
  {
    req.Abort();
  }
}

Answer 5

获取网页不是重点..重点是post...

Answer 6

post就用webclientSystem.Net.WebClient WebClientObj = new System.Net.WebClient();
            System.Collections.Specialized.NameValueCollection PostVars = new System.Collections.Specialized.NameValueCollection();
//下面这3行自己改，改成你要post的数据,前面是Name后面是对应的 value
            PostVars.Add("userid", ID);
            PostVars.Add("password", Pwd);
            PostVars.Add("phonenumber", destNumber);
byte[] byt = null;
            try
            {
                byt = WebClientObj.UploadValues(Url, "POST", PostVars);  //Url自己设，你要Post的页面Url
            }
            catch (WebException exc)
            {
                Trace.WriteLine(exc.Message);
            }            String StrReturn = System.Text.Encoding.GetEncoding("gb2312").GetString(byt);
            Trace.WriteLine(StrReturn);            if (StrReturn.IndexOf("已妥投", 0) != -1)
            {
                //成功了
            }

Answer 7

 System.Net.WebClient WebClientObj = new System.Net.WebClient();
            System.Collections.Specialized.NameValueCollection PostVars = new System.Collections.Specialized.NameValueCollection();
            ////下面这3行自己改，改成你要post的数据,前面是Name后面是对应的 value
            //PostVars.Add("userid", "ID");
            PostVars.Add("password", Pwd);
            PostVars.Add("mailNum", "EC244752724CN");
           
            byte[] byt = null;
            try
            {
                byt = WebClientObj.UploadValues("http://www.ems.com.cn/", "POST", PostVars);  //Url自己设，你要Post的页面Url
            }
            catch 
            {
                //Trace.WriteLine(exc.Message);
            }            String StrReturn = System.Text.Encoding.GetEncoding("gb2312").GetString(byt);
            richTextBox1.Text = StrReturn;
           
            if (StrReturn.IndexOf("已妥投", 0) != -1)
            {
                MessageBox.Show("OK");
            }
怎么不对呢?????????????

Answer 8

Answer 9

像ems这样的网站会不防异站post吗....一定有什么措施的....

Answer 10

你写的代码.用线程调用button1_Click(null,null)这个事件后.
void Step1 和void Step2 这两个事件为什么没触发呢.

Answer 11

不好意思，在过年，一直没来。在这里祝大家新年快乐，万事如意！

Answer 12

你用我的代码Post不对是因为你的目标Url不对
目标Url不是http://www.ems.com.cn/，是你接收post数据那个页面
例如http://www.ems.com.cn/qcgzOutQueryAction.do

Answer 13

webBrowser1  和这个  HttpWebRequest   在同一个机器上哪个快呢

Answer 14
