Title Body

I'm using Filestream for read big file (> 500 MB) and I get the OutOfMemoryException. I use Asp.net , .net 3.5, win2003, iis 6.0 I want this in my app: Read DATA from Oracle Uncompress file using FileStream and BZip2 Read file uncompressed and send it to asp.net page for download. When I read file from disk, Fails !!! and get OutOfMemory... . My Code is: using (var fs3 = new FileStream(filePath2, FileMode.Open, FileAccess.Read)) { byte[] b2 = ReadFully(fs3, 1024); } // http://www.yoda.arachsys.com/csharp/readbinary.html public static byte[] ReadFully(Stream stream, int initialLength) { // If we've been passed an unhelpful initial length, just // use 32K. if (initialLength < 1) { initialLength = 32768; } byte[] buffer = new byte[initialLength]; int read = 0; int chunk; while ((chunk = stream.Read(buffer, read, buffer.Length - read)) > 0) { read += chunk; // If we've reached the end of our buffer, check to see if there's // any more information if (read == buffer.Length) { int nextByte = stream.ReadByte(); // End of stream? If so, we're done if (nextByte == -1) { return buffer; } // Nope. Resize the buffer, put in the byte we've just // read, and continue byte[] newBuffer = new byte[buffer.Length * 2]; Array.Copy(buffer, newBuffer, buffer.Length); newBuffer[read] = (byte)nextByte; buffer = newBuffer; read++; } } // Buffer is now too big. Shrink it. byte[] ret = new byte[read]; Array.Copy(buffer, ret, read); return ret; } Now, I specify my issue better. Uncompress file using FileStream and BZip2 is OK, all is right. The Problem is the following: Read fat big file
