Bytes (1024) for string conversion (1 KB)?

Question

I would like to know if there is a function in .NET that converts numeric bytes to a string with the correct dimension?

Or do we just need to follow the old approach of separating and retaining conversion units to do this?

No no.

You can write the following:

public static string ToSizeString(this double bytes) {
    var culture = CultureInfo.CurrentUICulture;
    const string format = "#,0.0";

    if (bytes < 1024)
        return bytes.ToString("#,0", culture);
    bytes /= 1024;
    if (bytes < 1024)
        return bytes.ToString(format, culture) + " KB";
    bytes /= 1024;
    if (bytes < 1024)
        return bytes.ToString(format, culture) + " MB";
    bytes /= 1024;
    if (bytes < 1024)
        return bytes.ToString(format, culture) + " GB";
    bytes /= 1024;
    return bytes.ToString(format, culture) + " TB";
}
