Fail Loop

This gem is part of a code (C#) example that we got from a vendor recently. This exact same pattern appears multiple times in the example.

It stands out because it does manage work correctly...

using (FileStream rdr = new FileStream(contentInfo.FullName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{                    {
    index = 1;
    while (true)
    {
        long offset = (index - 1) * chunkSize;
        long remaining = contentInfo.Length - offset;
        if (remaining < 1) break; // Stop processing, at the end of the file

        // stuff that doesn't ever touch the index variable 

        index++;
    }
}
