Why are parameters not being passed?

Question

Programming

Service code:

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    public class Service1 : System.Web.Services.WebService
    {
        [WebMethod]
        [SoapDocumentMethod("Ping")]
        public string Ping(string pingString)
        {
            return pingString;
        }
    }

Proxy to call the Ping method on the web service:

    [WebServiceBinding("PingServer.Service1")]
    public class PingServiceProxy : SoapHttpClientProtocol
    {
        public PingServiceProxy()
        {
            base.Url = "http://localhost:53366/Service1.asmx";
        }

        [WebMethod]
        [SoapDocumentMethod("Ping")]
        public string Ping(string pingString)
        {
            return (string)base.Invoke("Ping", new object[] { pingString })[0];
        }
    }

The call itself:

    using (PingServiceProxy proxy = new PingServiceProxy())
            {
                Console.WriteLine(proxy.Ping("Hello, World!"));
            }

The call goes well, the proxy accesses the service, but the method receives null instead of a string, I can’t understand the reason. Moreover, if you call the method, for example, from the browser, the parameter comes normally. Those. the jamb turns out in implementation of a proxy.

It is not worth suggesting the use of WCF or other methods, you need an implementation in this way (and it is on .net no higher than the second Framework)

Answer 1

the client is missing the Namespace parameter in the WebServiceBinding attribute
