示例：调用webservice查询IP地址信息

webservice地址：http://www.wjg121.cn/Service/IPAddress.asmx?op=GetIPCountryAndLocal

      static void Main(string[] args)
        {

             
            //构造soap请求信息
            StringBuilder soap = new StringBuilder();
            soap.Append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
            soap.Append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
            soap.Append("<soap:Body>");
            soap.Append("<GetIPCountryAndLocal xmlns=\"http://tempuri.org/\">");
            soap.Append("<RequestIP>183.39.119.90</RequestIP>");
            soap.Append("</GetIPCountryAndLocal>");
            soap.Append("</soap:Body>");
            soap.Append("</soap:Envelope>");

            string url = "http://www.wjg121.cn/Service/IPAddress.asmx";
            Console.WriteLine(WebServiceUtility.GetSOAPReSource(url,soap.ToString()));           
            Console.ReadKey();

        }

//返回结果：

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.
xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
