我使用方法NumberToWords((将数字转换为单词C#，我想将所有单词添加到列表中。所以我像这样更改代码。
public List<String> NumberToWords(int number)
{
/* It will show wrong output when declare outside */
List<string> ttsEN = new List<string>();
var unitsMap = new[] { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
var tensMap = new[] { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };
if (number == 0)
{
ttsEN.Add("zero");
return ttsEN;
}
string words = "";
if ((number / 1000000) > 0)
{
words += NumberToWords(number / 1000000) + " million ";
ttsEN.Add(unitsMap[(number / 1000000)]);
ttsEN.Add("million");
number %= 1000000;
}
if ((number / 1000) > 0)
{
words += NumberToWords(number / 1000) + " thousand ";
ttsEN.Add(unitsMap[(number / 1000)]);
ttsEN.Add("thousand");
number %= 1000;
}
if ((number / 100) > 0)
{
words += NumberToWords(number / 100) + " hundred ";
ttsEN.Add(unitsMap[(number / 100)]);
ttsEN.Add("hundred");
number %= 100;
}
if (number > 0)
{
if (words != "")
{
words += "and ";
ttsEN.Add("and");
}
if (number < 20)
{
words += unitsMap[number];
/* If comment this line it's work but not show fifteen after and in output */
ttsEN.Add(unitsMap[number]);
}
else
{
words += tensMap[number / 10];
ttsEN.Add(tensMap[number / 10]);
if ((number % 10) > 0)
{
words += "-" + unitsMap[number % 10];
ttsEN.Add(unitsMap[number % 10]);
}
}
}
return ttsEN;
}
我想在 NumberToWords(( 之外的列表中添加更多字符串，例如
private void button1_Click(object sender, EventArgs e)
{
List<string> voiceEN = new List<string>();
voiceEN = NumberToWords("5051");
ttsEN.Add("at");
voiceEN = NumberToWords("50");
ttsEN.Add("end");
所以我必须使用 List ttsEN = new List((; 在 NumberToWords(( 之外。但是当我使用 List ttsEN = new List((; 在 NumberToWords(( 之外并运行此代码时，它会显示这样的输出，其中有 2 个 4 和 2 个 5。这是错误的输出。
four four thousand five five hundred and fifteen
如果我在ttsEN.Add(unitsMap[number](上发表评论; 它的工作，但不显示十五个之后和输出。
我更改为在 NumberToWords(( 之外声明这样的列表
List<string> ttsEN;
并在里面像这样使用
ttsEN = new List<string>();
但它显示这样的输出。如何使用列表外部方法添加更多字符串？
five
five
hundred
and
fifteen
下面的代码将打印five thousand and fifty-one [at] fifty [end]
但您应该考虑使用StringBuilder以获得更好的性能。你真的需要List<string>结果吗？您可以通过按空格字符拆分字符串来从字符串中提取列表：List<string> list = result.Split(' ').ToList();
class Program
{
static void Main(string[] args)
{
string line = string.Empty;
line += NumberToWords(5051);
line += " [at] ";
line += NumberToWords(50);
line += " [end]";
Console.WriteLine(line);
Console.ReadKey();
}
