Question

纠结了一下午了蛋都碎了。。

Answer 1

  string loginRespHtml = null;
            Dictionary<string, string> postDict = new Dictionary<string, string>();
           postDict.Add("__VIEWSTATE", "dDwtMTUxNzM0MjM0Mjs7Pot0nxzpyf7s6ZEFm%2F41QONw9iU9");
            //postDict.Add("codestring", "");
            postDict.Add("TextBox1",textBox1.Text);
            postDict.Add("TextBox2", textBox2.Text);
            postDict.Add("RadioButtonList1", "%D1%A7%C9%FA");
            postDict.Add("Button1", "");
            postDict.Add("lbLanguage", "");
            string baiduMainUrl = "http://61.139.105.138/xs_main.aspx";
            
                 loginRespHtml = getUrlRespHtml(baiduMainUrl, postDict);
            
            MessageBox.Show(loginRespHtml);
            webBrowser1.Navigate("about:blank");
            while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
            {
                Application.DoEvents();
            }
            webBrowser1.Document.Write(ConvertExtendedASCII(loginRespHtml));这是按按钮登录的代码。

            HttpWebResponse resp = getUrlResponse(url, postDict, "");            //long realRespLen = resp.ContentLength;            StreamReader sr;            sr = new StreamReader(resp.GetResponseStream(),     System.Text.Encoding.GetEncoding("GB2312"));            respHtml = sr.ReadToEnd();            return respHtml;        }
