将小写金额转换成为大写

如果有Bug，请留言我我及时的改。

public string FormatMoneyToUpper(decimal money) { bool isTrue = false;//判定是否为负值，是则为True否则为False if (money < 0) { //如果该值是负数，那先将该值转换为正数，然后将Istrue标记为True money=Math.Abs(money); isTrue = true; } //先转换为小数点后两位 string oldNum = Math.Round(money, 2).ToString(); //如果字符串中不存在"."那么就将他加".00" ,如果是一位小数则在后面补0; if (oldNum.IndexOf(".") == -1) { oldNum = oldNum + ".00"; } else if (oldNum.IndexOf(".") == oldNum.Length - 2) { oldNum = oldNum + "0";} char[] charArr = oldNum.ToCharArray(); string upper=""; string upperA = ""; string[] upperNum = {"零","壹","贰","叁","肆","伍","陆","柒","捌","玖"}; string[] unit = { "分", "角", "圆", "拾", "佰", "仟", "万", "亿" }; int len = 1; while (len <= oldNum.Length) { //判断每位对应的大写 switch (oldNum.Substring(oldNum.Length - len, 1)) { case ".": upperA = "圆"; break; case "0": upperA = "零"; break; case "1": upperA = "壹"; break; case "2": upperA = "贰"; break; case "3": upperA = "叁"; break; case "4": upperA = "肆"; break; case "5": upperA = "伍"; break; case "6": upperA = "陆"; break; case "7": upperA = "柒"; break; case "8": upperA = "捌"; break; case "9": upperA = "玖"; break; } //将数值后添加单位 switch (len) { case 1: upperA = upperA + "分"; break; case 2: upperA = upperA + "角"; break; case 3: upperA = upperA + ""; break; case 4: upperA = upperA + ""; break; case 5: upperA = upperA + "拾"; break; case 6: upperA = upperA + "佰"; break; case 7: upperA = upperA + "仟"; break; case 8: upperA = upperA + "萬"; break; case 9: upperA = upperA + "拾"; break; case 10: upperA = upperA + "佰"; break; case 11: upperA = upperA + "仟"; break; case 12: upperA = upperA + "億"; break; case 13: upperA = upperA + "拾"; break; case 14: upperA = upperA + "佰"; break; case 15: upperA = upperA + "仟"; break; case 16: upperA = upperA + "萬"; break; default: upperA += ""; break; } upper = upperA + upper; len++; } upper = upper.Replace("零拾", "零");// 处理101 壹佰零拾壹 upper = upper.Replace("零佰", "零");// 处理1001 壹仟零佰零拾壹 upper = upper.Replace("零仟", "零");// 处理10001 壹萬零仟零佰零拾壹 upper = upper.Replace("零零零", "零");//经过上面处理可能会出现 例如10001 就会是 壹萬零零零壹 upper = upper.Replace("零零", "零");//经过上面处理可能会出现 例如1001 就会是 壹仟零零壹 upper = upper.Replace("零角零分", "整");//1001.00 会出现 零角零分 upper = upper.Replace("零分", "整");//1001.50 会出现 零分 upper = upper.Replace("零角", "零");//1001.05 会出现 零角 upper = upper.Replace("零億零萬零圆", "億圆");// upper = upper.Replace("億零萬零圆", "億圆"); upper = upper.Replace("零億零萬", "億");//10000000001 壹佰零億零萬零壹圆整 upper = upper.Replace("零萬零圆", "萬圆"); upper = upper.Replace("零億", "億"); upper = upper.Replace("零萬", "萬"); upper = upper.Replace("零圆", "圆"); upper = upper.Replace("億萬", "億"); upper = upper.Replace("零零", "零"); //对零圆以下处理 if (upper.Substring(0, 1) == "圆") { upper = upper.Substring(1, upper.Length - 1); } if (upper.Substring(0, 1) == "角") { upper = upper.Substring(1, upper.Length - 1); } if (upper.Substring(0, 1) == "分") { upper = upper.Substring(1, upper.Length - 1); } if (upper.Substring(0, 1) == "零") { upper = upper.Substring(1, upper.Length - 1); } if (upper.Substring(0, 1) == "整") { upper = "零圆整"; } if (isTrue) { upper = "负" + upper; } return upper; }
