Streaming with WCF and MTOM

问题 I am using WCF bindings with streamed transfer mode, for both uploading and downloading binary content to/from a service. I've managed to get it working. I'll include the configuration, contracts, etc for reference. I've made some tests to benchmark different bindings and encodings. Uploading results seems ok. NetTcp being the fastest, followed by BasicHttp-MTOM and then BasicHttp-Text. What suprises me is that, when downloading large files, MTOM is very slow as opposed to Text encoding with

Can Stream.CopyTo() method save the streams incomplete?

问题 I have a WCF service which allows me to upload files in chunks. What I am wondering is could this code can cause the uploaded stream to be only partially appended to the target stream in any case? I have my logs that shows me that all the sent streams are 512000 byte(which I set on client side) and I've sent 6 chunks out of 9 chunks so far. But on server the files size is 2634325. Which means the last chunk sent(6th) is saved incompletely. What can be causing this behaviour? What should I do

问题 I have developed a bit of a complicated WCF Service method. I would like to use the Streaming transfer mode, and because I have more than one parameter, I have defined a MessageContract with a body and a header. [MessageContract] public class ReportAudioMessage { [MessageHeader] public int ReportId; [MessageHeader] public string FileName; [MessageHeader] public int FileLengthInBytes; [MessageHeader] public int LengthInSeconds; [MessageBodyMember] public Stream ReportAudio; } Notice the stream

Streamed transfer restrictions with WCF

问题 According to the following guide at MSDN, any operations that use streamed transfers can only have one input/output parameter. Link: http://msdn.microsoft.com/en-us/library/ms731913.aspx (see heading "Restrictions on Streamed Transfers") I'm using streamed transfers for a WCF service that lets clients/consumers upload files to it. The upload itself works fine, but I need a way of passing two more input parameters along with the Stream object: 'string filename' and 'int userid'. How would I go
