C#流转输分段上传

wcf 流传输上传文件不能分段上传的问题已解决。

技巧就是上传的流参数不用FileStream 用MemoryStream即可。

以下是代码:

服务契约类：

[ServiceContract()]
    public interface IMyServer
    {
        [OperationContract]
        void UploadFile(UploadPartMessage msg);


      
    }

消息契约：

 [MessageContract]
    public class UploadPartMessage
    {
        [MessageHeader]
        public string FileName { get; set; }
        [MessageHeader]
        public long FileLength { get; set; }

        /// 

        /// 保存上传的数据
        /// 
        [MessageBodyMember]
        public Stream Stream { get; set; }

        /// 

        /// 当前分块的大小
        /// 
           [MessageHeader]
        public int PartSize { get; set; }
       
        /// 

        /// 总分块数
        /// 
        [MessageHeader]
        public int TotalPartCount { get; set; }
           [MessageHeader]
        public int PartID { get; set; }
        [MessageHeader]
        public bool IsLastPart { get; set; }

        /// 

        /// 分块在文件中的位置
        /// 
        [MessageHeader]
        public long Position { get; set; }

       
    }

服务的实现

 [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, IncludeExceptionDetailInFaults = true)]
    class MyServer : IMyServer
    {




        string baseDirectory =Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"server")  ;
        public void UploadFile(UploadPartMessage msg)
        {
            Console.WriteLine("已经接收Part: "+m
