WCF streaming files

Question

I need to pass a memory stream to the WCF server , how do i need to add this data type in my data contract. I will eventually need to convert this to a memory stream and pass it on to my service layer.

datacontact[DataMember]

 Stream str = null; 

        public Stream File
        {
            get { return str;   }
            set { str = value;  }

        }

Here is the WCF Streaming page. I'm not really sure if (how) you can do this with a DataContract, the normal way is to specify streams in the OperationContract. Wouldn't that work for you?

Short summary:

• Sender produces the Stream
• Sender does not Close the Stream
• Receiver does close the stream
• Set the MaxReceivedMessageSize property of the binding to a value larger than the largest item you wish to transfer.
