Vista - Deserialize array as object

Hello Newsgroup,

I have trouble serializing a data contract that has a data member of
type object.
At runtime this member carries an array of strings and WCF fails to
deserialize this member:
Code:
[DataContract]
public class DC
{
private object _dcvalue;

public DC ()
{}

public DC (object v )
{
_dcvalue = v;
}

[DataMember]
public object DCValue
{
get { return _dcvalue; }
set { _dcvalue = value; }
}
}

The WCF Error Trace reads as follows:
Type 'System.String[]' with data contract name 'ArrayOfstring:http://
schemas.microsoft.com/2003/10/Serialization/Arrays' is not expected.
Add any types not known statically to the list of known types - for
example, by using the KnownTypeAttribute attribute or by adding them
to the list of known types passed to DataContractSerializer.

How do I transfer array types in data members of type objects?

Thanks in advance for your help!

You'll want to add the known type attribute:

[KnownType(typeof(String[]))]

to the DCValue DataMember.

I have the same problem.

But, setting the attribute
[KnownType(typeof(String[]))]

on a DataMember does not compile.

Error 2 Attribute 'KnownType' is not valid on this declaration type. It is only valid on 'class, struct' declarations.

I hope someone have a solution for this issue....
