Readable File Sizes

Published on 29 August 2010 at 22:28 by Adam

In an effort to fill up this blog with code, I will over the next few weeks be looking back over my snippets, finding useful methods and posting them. Today's feature is a simple text formatter, which converts a long (representing bytes) into a string, giving you a nice readable file size.

So without further ado:

private static string GetReadableBytes(long lSize)
{
    double size = lSize;
    if (size >= 1024 && size < 1048576)
        return string.Format("{0:#,0.00} KB", (size / 1024));

    else if (size >= 1048576 && size < 1073741824)
        return string.Format("{0:#,0.00} MB", (size / 1048576));

    else if (size >= 1073741824 && size < 1099511627776)
        return string.Format("{0:#,0.00} GB", (size / 1073741824));

    else if (size >= 1099511627776)
        return string.Format("{0:#,0.00} TB", (size / 1099511627776));

    else return string.Format("{0} B", size);
}

And here you can see the output.

/* Bytes                    Readable Size
 * =====                    =============
 * 436                  ->  436 B
 * 2159                 ->  2.11 KB
 * 36236                ->  35.39 KB

 * 3623647473473        ->  3.30 TB

Enjoy!
