Можно переписать данный метод под switch?

Question

    private string ReadableFileSize()
    {
        LoadFileInfo();
        var length = _info.Length;

        if (length < Math.Pow(1024, 1)) 
            return length + " B";               //lower than 1kb
        if (length < Math.Pow(1024, 2)) 
            return TrimSize(length, 1) + " KB"; //lower than 1mb
        if (length < Math.Pow(1024, 3)) 
            return TrimSize(length, 2) + " MB"; //lower than 1gb
        if (length < Math.Pow(1024, 4)) 
            return TrimSize(length, 3) + " GB"; //lower than 1tb

        return length + " TB";//return size in tb    
    }

    private string GetFileSize()
    {
        LoadFileInfo();

        var length = _info.Length;
        string[] sizes = { "B", "KB", "MB", "GB", "TB" };
        var order = 0;

        while (length >= 1024 && order < sizes.Length - 1) 
        {
            order++;
            length /= 1024;
        }

        var result = $"{length:0.##} {sizes[order]}";

        return result;
    }
