The length of the stream should be in the http header named Content-Length.
In case it's missing, you may read by chunks and cumulate the result:

 

                MemoryStream mem = new MemoryStream();

                byte[] buffer = new byte[BUFFER_LENGTH];

                int rd;

                while((rd = strm.Read(buffer, 0, buffer.Length)) > 0)
mem.Write(buffer, 0, rd);

                return mem.ToArray();

Libor and others

I'm probably missing the obvious but here is what I'm trying to do.

 

In C# I simply want to ready the stream into a byte array and then write the
byte array to a file.  However the stream that is returned by the GetObject
request doesn't support "seek" type operations so I cannot tell the length
of the stream.

 

What am I missing?

 

Here is the code I'm attempting to use.

 

                Stream strm = getobject.ResponseStream;

                long i = strm.Length;

                byte[] a = new byte[i];

                strm.Read(a, 0, a.Length);

                FileStream fs = new FileStream(@"c:\test.jpg",
FileMode.Create);

                fs.Write( a, 0, a.Length);

                fs.Close();

If you're asking about RETS 1.x, then yes.

If the request has been for only one photo (ID=entity:n, where n is not an
asterisk), the body of the response is usually the jpg (or other image)
file, unless there was any problem, in which case the response is usually
regular xml <RETS> response with non-zero reply code.

If more than one photo has been requested, a multipart response is returned
(See the specs, chapter 5.11).

I know I'm not the first person to ask but.  

 

Are photos returned in a byte stream from the GetObject Transaction or ?

 

Thanks.
