Winform用Post方式打开IE

1.主要实现Code

  void OpenNewIe(string url, string postData)///url是要post的网址，postData是要传入的参数
         {
             if (ie != null)///避免重复打开ie对象没有释放，抛出异常
             {
                 try
                 {
                     ie.Quit();
                 }
                 catch
                 {
                     ie = null;
                 }
             }
             ie = new InternetExplorer();
             object vPost, vHeaders, vFlags, vTargetFrame;
             vPost = Encoding.GetEncoding("GB2312").GetBytes(postData);///注意编码方式是GB2312，还是ASCII
             vFlags = null;
             vTargetFrame = null;
             vHeaders = "Content-Type: application/x-www-form-urlencoded" + Convert.ToChar() + Convert.ToChar();
             ie.Visible = true;
             ie.Navigate(url, ref vFlags, ref vTargetFrame, ref vPost, ref vHeaders);
         }

2.参数传递

  StringBuilder postData = new StringBuilder();
             postData.AppendFormat("uid={0}", HelpEncrypt.Encode(uid.ToString(), key));
             postData.AppendFormat("&serial_number={0}", HelpEncrypt.Encode(serial_number, key));

3.调用方法

  if (checkBoxNo.Checked)
             {
                 OpenNewIe(Parameter.Payaddress, postData.ToString());
             }

4.附加：用WebBrowser组件Post打开IE

 private void TransferWebForm_Load(object sender, EventArgs e)
         {
             string vHeaders = "Content-Type: application/x-www-form-urlencoded" + Convert.ToChar() + Convert.ToChar();
             byte[] vPost = Encoding.GetEncoding("GB2312").GetBytes(_postData);
             this.webBrowser1.Navigate(navigateUrl, null, vPost, vHeaders);
         }
