Question

I have two classes (Person and Address) that i need to send via wcf, the classes look like this:

public class PersoanaFizica :IExtensibleDataObject
{
    [DataMember]
    private Guid _id;
    [DataMember(Name = "Id")]
    protected virtual Guid Id
    {
        get { return _id; }
        set { _id = value; }
    }

    private ExtensionDataObject _extensionData;
    public virtual ExtensionDataObject ExtensionData
    {
        get
        {
            return _extensionData;
        }
        set
        {
            _extensionData = value;
        }
    }


    private string _firstName;
    [Searchable(PropertyName="FirstName")]
    [DataMember]
    public virtual string FirstName 
    {
        get { return this._firstName; }
        set { this._firstName = value; }
    }

    private string _lastName;
    [Searchable(PropertyName="LastName")]
    [DataMember]
    public virtual string LastName 
    {
        get { return this._lastName; }
        set { this. _lastName = value; }
    }

    private Address _address;
    [Searchable(PropertyName="Address")]
    [DataMember]
    public virtual Address Address 
    {
        get { return this._address; }
        set { this._address = value; }
    }
}

public class Address : IExtensibleDataObject
{
 [DataMember]
    private Guid _id;
    [DataMember]
    public virtual Guid Id
    {
        get { return _id; }
        set { _id = value; }
    }

    private ExtensionDataObject _extensionData;
    public virtual ExtensionDataObject ExtensionData
    {
        get
        {
            return _extensionData;
        }
        set
        {
            _extensionData = value;
        }
    }

        private string _country;
    [Searchable(PropertyName="Country")]
    [DataMember]
    public virtual string Country 
    {
        get { return this._country; }
        set { this._country = value; }
    }
// and some other properties related to the address
}

The problem is that when i try to send them via wcf, the client receives the Id properties set to 00000-0000-00000-00000 or something like this.

Any idea why this is happening? And how to serialize the proper values?

Answer 1

nope… did not help. I just looked at
the code generated by svcutil.exe
(thats what i use to generate my
client) and i couldn’t find an Id
property at all. I tried changing the
protected keyword to public and
everything worked fine. It seems that
the problem is with the fact that i
need the properties to be protected
and not public.

Denis – any chance at all that your WCF client uses the XmlSerializer (which only serializes public read/write properties with a get and set method) instead of the DataContractSerializer?? The DataContractSerializer would definitely serialize a protected property or field – it really doesn’t care about the .NET visibility modifiers….

You should see this in the WCF client side proxy being generated – do you have [DataContract] and [DataMember] attributes there, or do you see [XmlElement] and so forth?? Does your class in the WCF client side proxy have a [DataContractAttribute] or a [XmlTypeAttribute] on it??
