Reading & Writing in a Stream

[Ali]

Hi

I want to write (or read) to a stream, but the data is not byte array
I converted the data to byte array manually, but it is very slow, (becuse the data is very large)
Is another way for this kind of writing and reading

best regard
Ali.

Not all streams require byte arrays. Maybe try a StreamWriter for disk
output, or a StringWriter for writing to a string.

Hi Ali,

Are you talking about a stream to disk, than you can just do it as strings.
(unicode is standard)

I hope this helps,

Those aren't actually streams though - they're TextWriters, which are
sort of the *equivalent* of streams, but for text rather than binary
data.

No, streams deal solely with binary data. To convert between text data
and binary data, you need to use an encoding.

Jon,

This is maybe true, but the streamreader can be used to write direct data to
disk. You do not need to convert that first to a byte array. I explicitly
said "disk"

Yes, but a StreamWriter isn't a Stream.

Actually, the disk part here is irrelevant, as a StreamWriter can write
to any stream - a NetworkStream, MemoryStream, FileStream, whatever.
The important thing is that you don't write strings to a Stream though
- you write them to a TextWriter (such as StreamWriter) which might
well in turn write bytes to an underlying Stream.

Do you mind if I ask you to read this yourself again, without any comments
of me.

Sure. Have done. No problem with it as far as I can see.

A StreamWriter is a TextWriter. TextWriters deal with text, not binary
data - and a StreamWriter converts the text it is given *into* binary
data, which the stream it's created with can write. A stream itself
*only* deals with binary, not text.

The OP wants to know how to write data to a *stream*, so he can't do it
as strings - not without a StreamWriter or manually calling
Encoding.GetByt es etc.

Which bit of my post did you actually disagree with? Why do you feel
it's relevant whether or not the OP is writing to a disk?

(I missed something from your previous post, btw - a Stream*Reader*
doesn't write *anything* - it only *reads*.)

Hi Jon,

A newsgroup keep the messages open this is what you tell that is the
question from the OP

The OP wants to know how to write data to a *stream*, so he can't do it
as strings - not without a StreamWriter or manually calling
Encoding.GetByt es etc.

This is the question from the OP (copied from his message)
I want to write (or read) to a stream, but the data is not byte array.
I converted the data to byte array manually, but it is very slow, (becuse
the data is very large).
Is another way for this kind of writing and reading?
---------------------------------------------------------
I do not know if he means to mem. to http or to disk. Therefore I gave the
answer that if it is to disk, it is not necessary to make first that
bytearray.

I did not tell how, that could be done when he had asked for that or maybe
he had answered that it was not to disk and than I had given another answer.
