Calling webservice with complex parameters from c# client

Question

Hello, Here is a class ...

public class Authentification {

    private string userField;
    private string passwordField;
    public string user
    {
        get
        {
            return this.userField;
        }
        set
        {
            this.userField = value;
        }
    }

    public string password
    {
        get
        {
            return this.passwordField;
        }
        set
        {
            this.passwordField = value;
        }
    }

}

here the web service :

[WebMethod]
public Vehicle[] getVehiculeList(Authentification authentification)
{
....
}

Here the client and the call of webservice : (the same class Authentification like in the webservice has been defined)

Authentification azz = new Authentification() ;
azz.user = "toto";
azz.password = "tata";
string aa = ws.getVehiculeList(azz);

gives an error : Error 27 The best overloaded method match for 'WSCL.localhost.Service1.getVehiculeList(WSCL.localhost.Authentification)' has some invalid arguments

and

Error 28 Argument '1': cannot convert from 'WSCL.Authentification' to 'WSCL.localhost.Authentification'

Any help ?

Thank a lot !

Answer 1

What might have happened is that you have referenced the assembly containing the data entities (e.g. Authentication) on your client, and now you have both the proxied entity (WSCL.localhost.Authentification) and the original server entity (WSCL.Authentification). If you change your client's use of Authentication to use the proxied class (WSCL.localhost.Authentification) it should work.

If you switch to WCF, you will be able to move the data entities like Authentication into a separate assembly, and then Share this same type between your Service and your Client. AFAIK this isn't possible 'out of the box' in ASMX.
