通过HttpWebRequest调用webService

调用远端接口，向远端接口写入一个xml文件（loginLog为xml的字符串）。关键方法如下：

        public object InsertAuditLog(string loginLog)
        {

            //Wsdlxml(loginLog)返回wsdl的xml
            byte[] bs = Encoding.UTF8.GetBytes(Wsdlxml(loginLog));
            HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://10.109.209.90:21010/gather/services/AioxPort");

            myRequest.Method = "POST";
            myRequest.ContentType = "text/xml; charset=utf-8";
            //mediate为调用方法
            myRequest.Headers.Add("SOAPAction", "http://tempuri.org/mediate");
            myRequest.ContentLength = bs.Length;

            //Console.WriteLine("完成准备工作");
            using (Stream reqStream = myRequest.GetRequestStream())
            {
                reqStream.Write(bs, , bs.Length);
            }

            using (HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse())
            {
                StreamReader sr = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
                return sr.ReadToEnd();
                //Console.WriteLine("反馈结果" + responseString);
            }
            //Console.WriteLine("完成调用接口");
        }
