How create a WCF service with a class type parameter

Question

I'm trying to create a new service UpdateApplicationBidStatus and it should have two parameters -

 

1. ApplicationBidPayload (class)

2. PartnerId (Int)

 

ExchangeService.cs

public ExchangeService: IExchangeService
{
    public int UpdateApplicationBidStatus(ApplicationBidPayload _InputXml, string PartnerId)
   {
      //------
   }
}

IExchangeService.cs

[OperationContract]
[WebGet(UriTemplate = "/UpdateApplicationBidStatus/{InputXml}/{PartnerId}", RequestFormat = WebMessageFormat.Xml)]
int UpdateApplicationBidStatus(ApplicationBidPayload _InputXml, string PartnerId);

ApplicationBidPayload .cs class structure -

[Serializable]
[DataContract]
public class ApplicationBidPayload
{
[DataMember]
public PayloadApplication Applicant { get; set; }
}
public class PayloadPropertyAddress
{
[DataMember]
public string Flat { get; set; }
[DataMember]
public string BuildingName { get; set; }
[DataMember]
public string StreetNo { get; set; }
[DataMember]
public string StreetName { get; set; }
[DataMember]
public string Area { get; set; }
[DataMember]
public string Town { get; set; }
[DataMember]
public string County { get; set; }
[DataMember]
public string Postcode { get; set; }
}
public class PayloadApplication
{
[DataMember]
public string ApplicationId { get; set; }
[DataMember]
public string PropertyId { get; set; }
[DataMember]
public PayloadPropertyAddress PropertyAddress { get; set; }
[DataMember]
public string AdvertCloseDate { get; set; }
[DataMember]
public string BidStatus { get; set; }
[DataMember]
public string BidStatusDate { get; set; }
[DataMember]
public string PropertyLandlord { get; set; }
}
