数字转中文金额大写输出

数字转中文金额大写输出：

public string ToChineseAmount(decimal number)
{
    string s = number.ToString("#L#E#D#C#K#E#D#C#J#E#D#C#I#E#D#C#G#E#D#C#F#E#D#C#.0B0A");
    string d = Regex.Replace(s, @"((?<=\.)[0-9]..|(?!\.)[0-9]..)", m => "零壹贰叁肆伍陆柒捌玖"[(int)m.Value[0] - 48] + (m.Value[1] == '0' ? "" : "元空拾佰仟万空拾佰仟亿空拾佰仟万空拾佰仟整角分"[m.Value[1] - 'A']));
    
    // 二次正则：处理连续的零和单位冗余
    return Regex.Replace(d, @"零项|零拾|零佰|零仟|零亿|零万|零元", "零")
                .Replace("零零", "零")
                .Replace("零亿", "亿")
                .Replace("零万", "万")
                .Replace("零元", "元")
                .TrimStart('零').Replace("元零", "元");
}

 一行代码版：

string result = Regex.Replace(decimal.Parse(num).ToString("#L#E#D#C#K#E#D#C#J#E#D#C#I#E#D#C#G#E#D#C#F#E#D#C#.0B0A"), @"((?<=\.)[0-9]..|(?!\.)[0-9]..)", m => "零壹贰叁肆伍陆柒捌玖"[(int)m.Value[0] - 48] + (m.Value[1] == '0' ? "" : "元空拾佰仟万空拾佰仟亿空拾佰仟万空拾佰仟整角分"[m.Value[1] - 'A']));
