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(10) + Convert.ToChar(13);
            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(10) + Convert.ToChar(13);
            byte[] vPost = Encoding.GetEncoding("GB2312").GetBytes(_postData);
            this.webBrowser1.Navigate(navigateUrl, null, vPost, vHeaders);
        }
