How can i send a List<Stream> as part of WCF messageContract

Question

Hi All,

I want to send List<Stream> through wcf service.My contract is something below.

    [MessageContract]
    public class ResponseData 
    {
        /// <summary>
        /// 
        /// </summary>
        [MessageHeader]
        public CustomResult Result { get; set; }
        /// <summary>
        /// Stream Data
        /// </summary>
        [MessageBodyMember]
        public List<VolumeInfo> Info { get; set; }
    }

    /// <summary>
    /// 
    /// </summary>
    [MessageContract]
    public class VolumeInfo
    {
        /// <summary>
        /// 
        /// </summary>
        [MessageHeader]
        public int Index { get; set; }
        /// <summary>
        /// 
        /// </summary>
        [MessageBodyMember]
        public Stream Data { get; set; }
    }
	
API:
	[OperationContract]
	public ResponseData GetVolumeDeta();

Is there any way to do that?

Thanks in advance.

Hi @la07k-4914

Generally, the transmission of List data is transmitted using XML. You can convert your stream to a byte array and use the XmlSerializer class to transport it.
