湖北响应式网站建设企业,现在的seo1发布页在哪里,做同城购物网站赚钱吗,wordpress需要多少运存最近有个需求#xff0c;需要显示汉字数字#xff0c;比如一二三四五…这样子#xff0c;问题看起来挺简单#xff0c;但我没有找到有自带这样的转换的方法#xff0c;数字转汉字数字#xff0c;挺有意思的#xff0c;就简单研究了一下#xff1b; 百度了一下#xff…最近有个需求需要显示汉字数字比如一二三四五…这样子问题看起来挺简单但我没有找到有自带这样的转换的方法数字转汉字数字挺有意思的就简单研究了一下 百度了一下有个基本的思路就是预定义有个数字直接取
var baseStr new Liststring() { 零, 一, 二, 三, 四, 五, 六, 七, 八, 九, 十,};直接按下标就能实现1~10的转换了 但是超过10怎么办呢不可能把所有数字预定义啊。那就组合拼装一下
var baseStr new Liststring() { 零, 一, 二, 三, 四, 五, 六, 七, 八, 九, };
var signs new Liststring() { 十, 百, 千, 万,}一下子就把范围扩大大99999了通过各个位数的值进行转换这样你就可以会得到 “一十”“一十一”“一百零” “三千零零五”这样不符合表达的结果
算了文章不会写。总之经过一系列的演化直接上源码吧
准备好预定义的汉字数字兆后面都是百度来的
var signs new Liststring() { 十, 百, 千, 万, 亿, 兆, 京, 垓, 秭, 穰, 沟, 涧, 正, 载, 极, 恒河沙, 阿僧祇, 那由他, 不可思议, 无量大数 };var baseStr new Liststring() { 零, 一, 二, 三, 四, 五, 六, 七, 八, 九, };做个初始判断支持正负号
var charFirst numStr.First();int startNumIndex 0;string firstSign string.Empty;if (!char.IsNumber(charFirst)){if (!charFirst.Equals(-)){if (!charFirst.Equals()){outString $输入参数第一位“ {charFirst} ”既不是数字也不是正负符号。;return false;}firstSign 正;}else{firstSign 负;}startNumIndex 1;}var realStr numStr.Substring(startNumIndex, numStr.Length - startNumIndex);realStr.Trim();realStr.ToList().RemoveAll(p !char.IsNumber(p));var strTemp realStr.ToString();if (string.IsNullOrEmpty(strTemp)){outString $输入参数“ {numStr} ”没有数字;return false;}从各位开始判断拼接字符串
var werishu strTemp.Length;var strReverse strTemp.Reverse().ToList();var strResult string.Empty;bool isShowZero ShowZero();for (int index 0; index werishu; index){var ch strReverse[index];var tempNumber int.Parse(ch.ToString());strResult ${Trans(tempNumber, index - 1, isShowZero)}{strResult};if (tempNumber 0){isShowZero false;}}outString ${firstSign}{strResult};return true;是否显示“零的判断”处理“一百”“一千”“一万” 这样的情况
bool ShowZero(){var sub1 strTemp.IndexOf(0);bool need0 false;if (sub1 ! -1){var less strTemp.Length - sub1 - 1;if (werishu 1 ||(less 0 strTemp.Substring(sub1 1).Count(p p.Equals(0)) ! less)){// 不是连续的0,要保留显示“零”need0 true;}}return need0;}转换逻辑按位取对应数字和单位
string Trans(int value, int signIndex, bool showZero){if (value 1 signIndex 0){return signs[signIndex];}var strSign signs[0];strSign CalSign(signIndex); var tempResult ${GeStr(value, showZero)}{strSign };return tempResult;}获取对应数字的逻辑
string GeStr(int baseStrIdex, bool showZero){if (showZero){return baseStr[baseStrIdex];}return baseStrIdex 0 ? string.Empty : baseStr[baseStrIdex];}重点来了单位计算比如十万~千万是单位与单位的拼接
string CalSign(int signIndex){var strSign string.Empty;var realSignIndex signIndex;if (realSignIndex 4){return GetSignStr(realSignIndex);}int signSecond 4; // 到亿if (realSignIndex 7){// 到亿return ${GetSignStr(signIndex - signSecond)};}if (realSignIndex 7){return GetSignStr(signSecond);}realSignIndex - 7;var signLen 4;var n realSignIndex / signLen;if (realSignIndex n * signLen){return GetSignStr(n signSecond);}return strSign ${GetSignStr(realSignIndex - (n * signLen) - 1)};string GetSignStr(int indexTemp){return indexTemp -1 ? string.Empty : signs[indexTemp];}}至此完成
全部带入如下复制粘贴即可
