Not WCF compatible

Question

Hello,

i am pretty new in WCF. So I don't understand why the WCF-Testclient cannot handle following Class. It is always telling me on methods, where I use followng class, that WCF-Testclient does not support this method, because of type GeoObject.

public class GeoObject
  {
    [DataMember]
    public long Id;

    [DataMember]
    public int CreaterId;

    [DataMember]
    public System.DateTime CreationDate;

    [DataMember]
    public Dictionary<String, PropertyValueObject> Properties;
    
    [DataMember]
    public System.Nullable<double> Longitude;

    [DataMember]
    public System.Nullable<double> Latitude;

    [DataMember]
    public System.DateTime LastUpdate;

    [DataMember]
    public VisibleState VisibleState;

   
    public GeoObject()
    {
     // [...]
    }

    
    public Dictionary<String, PropertyValueObject> getAllPropertiesWithoutSublists()
    {
     // [...]
    }

  
    protected Dictionary<String, PropertyValueObject> getSubPropertiesWithoutSublists(Dictionary<String, PropertyValueObject> parent)
    {
     // [...]
    }
  }

If I add some datamembers it is not changing. But I think I tried all datamembers in another class in similar way, and was working.

Thanks for any help.

Answer 1

1. Da fehlt das DataContract Attibute über der Klassen Deklaration.
2. Worher kommt das PropertyValueObject? Wenn es deine eigene Klasse ist, muss diese auch mit den Data... Attributen versehen werden.

Answer 2

Hallo, danke für die Antwort. Leider hab ich hier zuviel gekürzt. Vor beiden public class GeoObject/PropertyValueObject steht
    [DataContract]

wie auch bei anderen Klassen auch. Hier nochmal PVO:

 public class PropertyValueObject
  {
    private PropertyTypeEnum _valueType;
    [DataMember]
    public PropertyTypeEnum ValueType 
    {
      get { return this._valueType; }
      set { this._valueType = value; }
    }
    
    private long _propertyObjectId;
    [DataMember]
    public long PropertyObjectId
    {
      get { return this._propertyObjectId; }
      set { this._propertyObjectId = value; }
    }


    private Object _propertyValue;
    [DataMember]
    public Object PropertyValue
    {
      get 
      {
        [...]

        return retValue;
      }

      set { this._propertyValue = value; }
    }
  }

Teste mal [DataContract(IsReference=true)] über die Klassen und teste es nochmal.
