WPF 将数字转化为中文大写

WPF 中可以使用以下代码将数字转化为中文大写：

public static string ConvertNumberToChinese(double number)
{
    string[] numArray = new string[] { "零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖" };
    string[] unitArray = new string[] { "元", "拾", "佰", "仟", "万", "拾", "佰", "仟", "亿" };

    string result = "";
    string str = Math.Round(number, 2).ToString();
    int length = str.Length;
    int zeroCount = 0;
    for (int i = 0; i < length; i++)
    {
        int num = int.Parse(str[i].ToString());
        int unitNum = length - i - 1;
        string unit = unitArray[unitNum];
        if (num == 0)
        {
            zeroCount++;
            if (unitNum == 4 && zeroCount < 4)
            {
                result += unitArray[unitNum];
                zeroCount = 0;
            }
        }
        else
        {
            if (zeroCount > 0)
            {
                result += numArray[0];
                zeroCount = 0;
            }
            result += numArray[num] + unit;
        }
    }
    if (zeroCount > 0 && length >= 5)
    {
        result += "零";
    }
    result += "整";
    return result;
}

调用方法：

double number = 1234567890.12;
string chinese = ConvertNumberToChinese(number);

输出结果：

壹拾贰亿叁仟肆佰伍拾陆万柒仟捌佰玖拾元壹角贰分整
