async file write

[mander23]

I would like to be able to async file write. I would like to open a file and I would get the length like so.
fs.Read(buffer, 0, buffer.Length)

then I would like to open 2 filestream and write at the same time so it doesn't take as long. For example if the total length of the file is 100. I would split up and write 0-50 on one filestream and 51-100 on the second filestream, only writing them at the same time. Is this possible? Thank you.

No. You would have the file open with stream 1 and you would get a write error on the second stream. If for some reason you didn't get a file write error, your data would be interwoven.

you would get something like:
line 1
line 2
line 51
line 3
line 52
...

You could overlap writing out 2 separate text files.

What do you mean by overlap. THe file I have is a tif file. Is there someway I can do it with that.

A filestream is a file stream. the bytes you dump out are irrelevant. Whether your pic comes out jumbled or your homework gets saved out of order...

if you were able to pass a reference to an open file stream, or reference the open file stream from a thread you still run into this problem:

Rather than asking kid 1 to tell you the first half of the story then asking kid 2 to tell you the second half,
you have kid 1 tell you the first line of the first half of the story, then kid 2 tells you the first line of the second half of the story. it won't make sense when it's done.
