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, 0, 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");        }
