如何在不使用WebReference的情况下调用WebService

Question

我想知道是否有人使用类来调用WebService，这个WS在组织引用后接收一个整数，并响应到一个json文件

实际上，我的问题是在不使用webreference的情况下调用webservice，读取json文件并将其解析为字典

我感谢你的帮助

致以最良好的问候，我让你我的代码

    class ConsumirWebService

        public void ConsumirWS()
        {
            Dimex.ChangeSAP.Core.Entities.Seguridad.Usuario users = new Dimex.ChangeSAP.Core.Entities.Seguridad.Usuario();
            int idUsuaro = users.IdUsuario;
            try
            {
                System.Net.WebRequest req = System.Net.WebRequest.Create("http://192.168.8.97/PassportPruebas/api/partners?enterprise_system_id=1&organizational_reference=" + idUsuaro);
                //req.Proxy = new System.Net.WebProxy(ProxyString, true);
                //Add these, as we're doing a POST
                req.ContentType = "application/x-www-form-urlencoded";
                req.Method = "POST";
                //We need to count how many bytes we're sending. 
                //Post'ed Faked Forms should be name=value&
                string postData = "OPERATION_NAME=ADD_REQUEST&TECHNICIAN_KEY=90BA&INPUT_DATA=" + sendXML;
                byte[] bytes = System.Text.Encoding.ASCII.GetBytes(postData);
                req.ContentLength = bytes.Length;
                System.IO.Stream os = req.GetRequestStream();
                os.Write(bytes, 0, bytes.Length); //Push it out there
                os.Close();
                System.Net.WebResponse resp = req.GetResponse();
                if (resp == null)
                {
                    return null;
                }
                System.IO.StreamReader sr =
                      new System.IO.StreamReader(resp.GetResponseStream());
                string respuesta = sr.ReadToEnd().Trim();
                return respuesta;
            }
            catch (Exception ex)
            {
                return "";
                //throw or return an appropriate response/exception
            }

        }
    }

实际上，这也是我为任何有这种问题的人编写的代码，

        public static string LlamarWebService(string url)
        {
            try
            {
                System.Net.WebRequest req = System.Net.WebRequest.Create(url);
                req.ContentType = "application/json";
                req.Method = "GET";
                System.Net.WebResponse resp = req.GetResponse();
                if (resp == null) return null;
                System.IO.StreamReader sr =
                      new System.IO.StreamReader(resp.GetResponseStream());
                string respuesta = sr.ReadToEnd().Trim();
                return respuesta;
            }
            catch (Exception ex)
            {
                throw ex;
                // return "";
                //throw or return an appropriate response/exception
            }
        }

您可以在visualstudio命令提示符下使用wsdl实用程序或svcutil创建代理类输入命令wsdl.exe/out:[文件的路径和名称]/language:CS
