Serializability of enum-like class
- by callisto
I need to access an enum through a webservice.
As a webservice allocates 0 based integers to an enumeration (ignoring preset values in enum definition), I built the following:
public class StatusType
{
public StatusVal Pending { get { return new StatusVal( 1, "Pending"); } }
public StatusVal Authorised { get { return new StatusVal(2, "Authorised"); } }
public StatusVal Rejected { get { return new StatusVal(3, "Rejected"); } }
public StatusVal Sent { get { return new StatusVal(4, "Sent"); } }
public StatusVal InActive { get { return new StatusVal(5, "InActive"); } }
public List<StatusVal> StatusList()
{
List<StatusVal> returnVal = new List<StatusVal>();
StatusType sv = new StatusType();
returnVal.Add(sv.Pending);
returnVal.Add(sv.Authorised);
returnVal.Add(sv.Rejected);
returnVal.Add(sv.Sent);
returnVal.Add(sv.InActive);
return returnVal;
}
}
public class StatusVal
{
public StatusVal(int a, string b)
{
this.ID = a;
this.Name = b;
}
public int ID { get; set; }
public string Name { get; set; }
}
I then get the list of StatusVal with the following webmethod:
[WebMethod]
public List<ATBusiness.StatusVal> GetStatus()
{
ATBusiness.StatusType a = new ATBusiness.StatusType();
return a.StatusList();
}
I cannot however use this webmethod as referring it, I get the error: StatusVal cannot be serialized because it does not have a parameterless constructor.
I don't quite understand: should I pass params into the StatusValue type defined as the WebMethod's return Type?
I need this to return a list of StatusVals as per the StatusList() method.
