How to set a property in a WCF service from client side

Hello everyone,

first of all I am new to WCF. That is the basic problem to my problem, I know!

I want to make a call to my WCF service and in that works OK.
What I want is that each call to the Service contains a filled LoginUser object.

C#

[Serializable]
    [DataContract]
    public class LoginUser
    {
        [DataMember]
        public string UserName { get; set; }
        [DataMember]
        public string Password { get; set; }
    }

In my Interface I state:

C#

BLL.LoginUser LoginUser { [OperationContract] get; [OperationContract]set; }

In my service class I have:

C#

public BLL.LoginUser LoginUser { [OperationBehavior]get; [OperationBehavior]set; }

In the client I get 2 methods (get_LoginUser() ans set_LoginUser()) but I want to see a property.

I tested with these methods and I can set the values for UserName and Password with the method, but when calling the next method my Loginuser object is NULL again.

That is why I want to have a property to set and that in the next call the LoginUser object still has the data.

I do not want to add the object of LoginUser as a parameter in the WCF call or is that the only option?

I instantiate my call to the service as:

C#

srPersonal.IStatistics sc = new srPersonal.StatisticsClient();

I then want to do a

C#

srPersonal.BLL.LoginUser lu = new srPersonal.BLL.LoginUser();
lu.UserName = "hi";
lu.Password = "*****";
sc.LoginUser = lu;
var result = sc.GetMyData();

What do I have to change?

WCF don't allow properties on interfaces. The 'get' and 'set' will work as a methods, but not as a property.

In your case, this will work:

C#

ServiceReference1.IService1 proxy = new ServiceReference1.Service1Client();
ServiceReference1.LoginUser lu =
    new ServiceReference1.LoginUser() { UserName = "hi", Password = "****" };
proxy.set_UserLogin(lu);
var result = proxy.get_UserLogin();

You could do a regular basic authentication. It is some work, but it is a better way to handle user name and passwords.
