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.

Hi Jon,

I forgot to thank you for this greath answer.

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

I hope that I do not disappoint you, when I tell you that I did know that
already but made a typo.

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 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.

Why though? How would you do things differently if it's writing to a
disk compared with writing anywhere else?
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.

Well, you said you could write strings directly using a stream, which
you can't - you need to wrap it with a StreamWriter first, and that's
true whether the stream is to memory, the network or wherever.

Hi Jon,

Show me where I wrote that above, this is the X th time you are telling from
people what they said, while they did not.

So copy it where I wrote that and show it.

But as usualy you answer this not anymore because you cannot.

My mistake, you didn't use the word "directly". However, you did say:

<quote>
Are you talking about a stream to disk, than you can just do it as
strings.
</quote>

Which you can't. You can't (directly - my word) write a string to a
stream. You *have* to go through a conversion process (which is what
the OP apparently wanted to avoid) whether that's done directly using
Encoding or using StreamWriter. It doesn't matter whether you're
writing to a disk or not.

Your post gave the impression (to me at least) that you thought you
could write strings directly to a stream, which you can't.

Hi Jon,

Your post gave the impression (to me at least) that you thought you
could write strings directly to a stream, which you can't.

Did you see me write here that I thought that you said that it was only
possible to write bytearrays to disk?

That I could have been writing very easy by what you where telling and than
telling to you that you can only write bytes to a disk.

I expect that you know those basic things.

No, I didn't - but that's basically true. Of course, you can *convert*
strings to byte arrays using StreamWriter, but it's still going to
write bytes to disk, one way or other.
That I could have been writing very easy by what you where telling and than
telling to you that you can only write bytes to a disk.

Sorry, could you rephrase that? I didn't understand that sentence.

I still say it's irrelevant whether or not the OP's stream is writing
to disk though.

Not needed see the phrase of you before that, the meaning is almost exactly
the same.
