Upload Image to WCF Rest Service

Jul 19, 2012 02:20 PM|LINK

Hi to all

  I have created the WCF Rest service to upload images.Now it is working,
  but when i open the uploaded image after converting from stream to image it is
  showing error can anyone guide what mistake i am doing.

Operation Contract :
 
 [OperationContract]
      [WebInvoke(BodyStyle = WebMessageBodyStyle.Bare, UriTemplate = "/PostImage", Method = "POST")]
      PublicMessage PostImage(Stream obj);

Service Definition :
 

public PublicMessage PostImage(Upload obj)
    {
        byte[] buffer = StreamToByte(obj.File);   //Function to convert the stream to byte array
     FileStream fs = new FileStream(@"D:\ShopMonkeyApp\Desert.jpg", FileMode.Create, FileAccess.ReadWrite);
        BinaryWriter bw = new BinaryWriter(fs);

        bw.Write(buffer);

        bw.Close();

        return new PublicMessage { Message = "Recieved the image on server" };
    }


public static byte[] StreamToByte(Stream stream)
      {
        byte[] buffer = new byte[16 * 1024];
        using (MemoryStream ms = new MemoryStream())
        {
          int read;
          while ((read = stream.Read(buffer, 0, buffer.Length)) > 0)
          {
            ms.Write(buffer, 0, read);
          }

          return ms.ToArray();

        }

      }



Client Application :

        string obj = @"D:\Images\Desert.jpg";
        var c = new System.Net.WebClient();
        c.OpenWrite(string.Concat("http://localhost:50268/shopmonkey.svc", "/PostImage"), "POST");
        c.Headers[HttpRequestHeader.ContentType] = "application/octet-stream";
        c.UploadFile("http://localhost:50268/shopmonkey.svc/PostImage"), obj);



Thanks & Regards,
Vijay
