C#中把货币、日期转换成中文大写

日期转换代码如下：

/// <summary> /// 日期转换为中文大写 /// </summary> public class UpperConvert { public UpperConvert() { // // TODO: 在此处添加构造函数逻辑 // } //把数字转换为大写 public string numtoUpper(int num) { String str=num.ToString(); string rstr = ""; int n; for (int i = 0; i < str.Length; i++) { n =Convert.ToInt16(str[i].ToString());//char转数字,转换为字符串，再转数字 switch (n) { case 0:rstr=rstr+"〇";break; case 1:rstr=rstr+"一";break; case 2:rstr=rstr+"二";break; case 3:rstr=rstr+"三";break; case 4:rstr=rstr+"四";break; case 5:rstr=rstr+"五";break; case 6:rstr=rstr+"六";break; case 7:rstr=rstr+"七";break; case 8:rstr=rstr+"八";break; default:rstr=rstr+"九";break; } } return rstr; } //月转化为大写 public string monthtoUpper(int month) { if (month < 10) { return numtoUpper(month); } else if (month == 10) { return "十"; } else { return "十" + numtoUpper(month - 10); } } //日转化为大写 public string daytoUpper(int day) { if (day < 20) { return monthtoUpper(day); } else { String str = day.ToString(); if (str[1] == '0') { return numtoUpper(Convert.ToInt16(str[0].ToString()))+"十" ; } else { return numtoUpper(Convert.ToInt16(str[0].ToString())) + "十" + numtoUpper(Convert.ToInt16(str[1].ToString())); } } } //日期转换为大写 public string dateToUpper(System.DateTime date) { int year = date.Year; int month = date.Month; int day = date.Day; return numtoUpper(year) + "年" + monthtoUpper(month) + "月" + daytoUpper(day) + "日"; } }

 

货币转换代码：

/// <summary> /// MoneyConvert 的摘要说明 /// </summary> public class MoneyConvert { public MoneyConvert() { // // TODO: 在此处添加构造函数逻辑 // } public string GetUpper(string numstr) { try { decimal num = Convert.ToDecimal(numstr); return GetUpper(num); } catch { return "非数字形式！"; } } public string GetUpper(int numint) { try { decimal num = Convert.ToDecimal(numint); return GetUpper(num); } catch { return "非数字形式！"; } } /**/ /// <summary> /// 转换人民币大小金额 /// </summary> /// <param name="num">金额</param> /// <returns>返回大写形式</returns> public string GetUpper(decimal num) { string strUpperMum = "零壹贰叁肆伍陆柒捌玖"; //0-9所对应的汉字 string strNumUnit = "万仟佰拾亿仟佰拾万仟佰拾元角分"; //数字位所对应的汉字 string strOfNum = ""; //从原num值中取出的值 string strNum = ""; //数字的字符串形式 string strReturnUpper = ""; //人民币大写金额形式 int i; //循环变量 int sumLength; //num的值乘以100的字符串长度 string ch1 = ""; //数字的汉语读法 string ch2 = ""; //数字位的汉字读法 int nzero = 0; //用来计算连续的零值是几个 int temp; //从原num值中取出的值 num = Math.Round(Math.Abs(num), 2); //将num取绝对值并四舍五入取2位小数 strNum = ((long)(num * 100)).ToString(); //将num乘100并转换成字符串形式 sumLength = strNum.Length; //找出最高位 if (sumLength > 15) { return "溢出"; } strNumUnit = strNumUnit.Substring(15 - sumLength); //取出对应位数的strNumUnit的值。如：200.55,sumLength为5所以strNumUnit=佰拾元角分 //循环取出每一位需要转换的值 for (i = 0; i < sumLength; i++) { strOfNum = strNum.Substring(i, 1); //取出需转换的某一位的值 temp = Convert.ToInt32(strOfNum); //转换为数字 if (i != (sumLength - 3) && i != (sumLength - 7) && i != (sumLength - 11) && i != (sumLength - 15)) { //当所取位数不为元、万、亿、万亿上的数字时 if (strOfNum == "0") { ch1 = ""; ch2 = ""; nzero = nzero + 1; } else { if (strOfNum != "0" && nzero != 0) { ch1 = "零" + strUpperMum.Substring(temp * 1, 1); ch2 = strNumUnit.Substring(i, 1); nzero = 0; } else { ch1 = strUpperMum.Substring(temp * 1, 1); ch2 = strNumUnit.Substring(i, 1); nzero = 0; } } } else { //该位是万亿，亿，万，元位等关键位 if (strOfNum != "0" && nzero != 0) { ch1 = "零" + strUpperMum.Substring(temp * 1, 1); ch2 = strNumUnit.Substring(i, 1); nzero = 0; } else { if (strOfNum != "0" && nzero == 0) { ch1 = strUpperMum.Substring(temp * 1, 1); ch2 = strNumUnit.Substring(i, 1); nzero = 0; } else { if (strOfNum == "0" && nzero >= 3) { ch1 = ""; ch2 = ""; nzero = nzero + 1; } else { if (sumLength >= 11) { ch1 = ""; nzero = nzero + 1; } else { ch1 = ""; ch2 = strNumUnit.Substring(i, 1); nzero = nzero + 1; } } } } } if (i == (sumLength - 11) || i == (sumLength - 3)) { //如果该位是亿位或元位，则必须写上 ch2 = strNumUnit.Substring(i, 1); } strReturnUpper = strReturnUpper + ch1 + ch2; if (i == sumLength - 1 && strOfNum == "0") { //最后一位（分）为0时，加上“整” strReturnUpper = strReturnUpper + '整'; } } if (num == 0) { strReturnUpper = "零元整"; } return strReturnUpper; } }
