Thread: Binary Reader Buffer size

Hello,

I woud like to read a very big binary file in C#. Say, 256 Mega Bytes of data. Actually I should read from one big 256Mbytes file and append to another file.
How do I append to my original file?
can i use some thing like this?

Code:

public static byte[] ReadFully (Stream stream)
{
byte[] buffer = new byte[268435456];
using (MemoryStream ms = new MemoryStream())
{
while (true)
{
int read = stream.Read (buffer, 0, buffer.Length);
if (read <= 0)
return ms.ToArray();
ms.Write (buffer, 0, read);
}
}
}

any help, suggestions is appreciated.


Thanks,
