WCF Service to display on a Winform its current data - visual-studio

Question

I'm making a 2-stage "reservation management" program that other Software interacts with via WCF messages. Clients can claim a reservation, and release a reservation they previously had laid claim to. I'd like all this reservation info to be viewable on a WinForm for the host.
What I'm not sure how to accomplish is getting data from the Service into my WinForm. Im still very green when it comes to WCF stuff, I followed the MSDN guide to get that skeleton, but they didnt go into much detail tying to GUIs, or having any stored info.
My Service:
namespace ReservationServiceLib
{
public class reservation
{
public string location;
public bool claimed;
public string currentHolder;
public reservation(string l)
{
location = l;
claimed = false;
currentHolder = "host";
}
}
public class ReservationService : IReservationService
{
public bool reservationManagerLocked= false;
public List<reservation> keys = new List<reservation>();
private static Mutex managerLock = new Mutex();
public bool GetAccess(string n1)
{
//get acceess lock for using the reservationManager
return true;
}
public bool ClaimReservation(string rez, string clientN)
{
//Client requests/retrieves key
if(reservationManagerLocked!=true)
{
int i = 999;
i = keys.IndexOf(keys.Find(delegate (reservation x) { return x.location == rez; }));
if((keys[i].claimed == false) && (i < 999))
{
i = 999;
keys[i].claimed = true;
keys[i].currentHolder = clientN;
return true;
}
}
return false;
}
public bool ReleaseReservation(string n1)
{
//Client relenquishes access to key
return true;
}
And my "host" Winform:
namespace ReservationManager
{
public partial class ReservationManager : Form
{
public void populateComboBox()
{
for (int x = 0; x < dataGridView_IZone.Rows.Count-1; x++)
{
//comboBox_keyNames.Items.Add(dataGridView_IZone.Rows[x].Cells[0].Value);
}
}
public IZoneManager()
{
//create Keys and add to service's store of keys
//setup GUI
InitializeComponent();
// Step 1: Create a URI to serve as the base address.
Uri baseAddress = new Uri("http://localhost:8000/ReservationServiceLib/");
CalculatorService CSs = new CalculatorService();
// Step 2: Create a ServiceHost instance.
ServiceHost selfHost = new ServiceHost(typeof(ReservationService), baseAddress);
try
{
// Step 3: Add a service endpoint.
selfHost.AddServiceEndpoint(typeof(IReservation), new WSHttpBinding(), "ReservationService");
// Step 4: Enable metadata exchange.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
selfHost.Description.Behaviors.Add(smb);
// Step 5: Start the service.
selfHost.Open();
Console.WriteLine("The service is ready.");
}
catch (CommunicationException ce)
{
Console.WriteLine("An exception occurred: {0}", ce.Message);
selfHost.Abort();
}
}
}
}
