Web服务函数调用中的out参数问题

Question

I have the following function in my web service:

[WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
    // [System.Web.Script.Services.ScriptService]
 public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";

        }

        [WebMethod]
        public void Login(string url, string id, out int ClientType, out int ClientID)
        {
            ClientID = 11;
            ClientType = 12;
        }
    }
}

On the client side I see it in object reference without the out parameter this is the whole code , I am interested in public void Login(string url, string id, out int ClientType, out int ClientID) , I just want to use in on the client side with as I see it on the server side.What changes I should do in the server that I will puslish It with out changes.

    }
}

Any idea why I dont see the out parameter there, and why I cannot use it?

Answer 1

With the help of John Saunders , thanks again , I know what to search .

I have found this answer how to generate web service out of wsdl

And It was exactly what I needed .

Answer 2

I think this similar question might help you out.

Is it unusual for a web service call to have an "out" parameter?

Also, you could just make a struct or class that bundles up your two out parameters and returns it something like this.

public class LoginResult
{
    public LoginResult(int clientType, int clientId)
    {
         ClientType = clientType;
         ClientID = clientId;
    }

    public int ClientType { get; set; };
    public int ClientID{ get; set; };
}

[WebMethod]        
public LoginResult Login(string url, string id)
{
    return new LoginResult( 11, 12 );      
}

Answer 3

It will be in the LoginResponseBody . IIRC the method will be modified on the client side so that it returns a value. Or maybe inside LoginRequest .
