I get following error when i upload files larger than 500 MB
"Exception of type 'System.OutOfMemoryException' was thrown. "
My code is shown below:
public readonly string Filename, ContentType;
public readonly int Size;
public readonly byte[] Bytes;
public FileHolder(HttpPostedFile file)
{
Filename = Path.GetFileName(file.FileName);
ContentType = GetContentType(file.ContentType, Filename);
Size = file.ContentLength;
Bytes = new byte[file.InputStream.Length]; //Here i get error
file.InputStream.Read(Bytes, 0, Size);
}
Don't try to read the entire stream all at once. You won't get the entire stream all at once anyway.
Create a buffer with a reasonable size, then read a block at a time:
byte[] buffer = new byte[8192];
int offset = 0;
int left = Size;
while (left > 0) {
int len = file.InputStream.Read(buffer, 0, Math.Min(buffer.Length, left));
left -= len;
// here you should store the first "len" bytes of the buffer
offset += len;
}
You should not load the entire file into a byte array. Instead, you can process the file directly from the input stream.
