Answer 1

I use this code to avoid "G29" scientific notation:

public static string DecimalToString(this decimal dec)
{
    string strdec = dec.ToString(CultureInfo.InvariantCulture);
    return strdec.Contains(".") ? strdec.TrimEnd('0').TrimEnd('.') : strdec;
}

EDIT: using system CultureInfo.NumberFormat.NumberDecimalSeparator :

public static string DecimalToString(this decimal dec)
{
    string sep = CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator;
    string strdec = dec.ToString(CultureInfo.CurrentCulture);
    return strdec.Contains(sep) ? strdec.TrimEnd('0').TrimEnd(sep.ToCharArray()) : strdec;
}
