私は英語の単語プログラムに単純な数字を作ろうとしていますが、配列を使用することにしました。ただし、99 より大きい数値を入力すると、3 番目の if 句でエラーが発生します。これを修正するには、何を変更する必要がありますか? これが私のコードです。

    class Program
    {
        static void Main(string[] args)
        {
         string[] uptonineteen = {"Zero","One","Two","Three","Four",
        "Five","Six","Seven","Eight","Nine","Ten",
        "Eleven","Twelve","Thirteen","Fourteen","Fifteen",
        "Sixteen","Seventeen","Eighteen","Nineteen"};
        string[] ten = {"","","Twenty","Thirty","Forty","Fifty",
        "Sixty","Seventy","Eighty","Ninety",};
        Console.WriteLine(" ---------------");
        int i = int.Parse(Console.ReadLine());
            if (i < 20)
            {
                Console.WriteLine(uptonineteen[i]);
            }
            if (i < 100)
            {
                Console.WriteLine(ten[i / 10] + ((i % 10 > 0) ? "" + uptonineteen[i%10] : ""));
            }
            if (i <= 999)
            {
                object lenthree = ten[i / 100] + "hundred"+" " + ((i % 100 > 0) ? "and" +" "+  uptonineteen[i % 1000] : "");
                Console.WriteLine(lenthree);
            } 
            Console.ReadKey();
        }
    }
}

私はこれを何度も見てきました...これは、小切手の書き込みなどを処理し、数百万、数千、最後にセントを含める必要がある場合があります...

public class NumToWords
{
    public NumToWords()
    {}

    string[] OneToNineteen = 
        { "zero",   
          "one",    "two",    "three",    "four",     "five",    "six",     "seven",     "eight",    "nine",   "ten",   
          "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };

    // empty string for zero-place-holder for tens grouping
    string[] Tens = { "", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

    // leave blank for "hundreds" because you would NOT do 123 as One hundred twenty-three hundred.
    string[] Block3Section = { "", "thousand", "million", "billion" };


    public string ToEnglish(int num)
    {
        int Block3Seq = 0;
        int curSegment;
        int tmp;
        string FinalWords = "";
        string curWord = "";

        while (num > 0)
        {
            curSegment = num % 1000;    // get only 3 digits worth (right) of the number
            num = (num - curSegment) / 1000;  // subtract this portion from the value

            if (curSegment > 0)
            {
                // always add the closing word as we HAVE something to build out
                curWord = "";

                // how many "hundreds" of the current segment
                tmp = (int)curSegment / 100;
                if (tmp > 0)
                    curWord += " " + OneToNineteen[tmp] + " hundred";

                // what is remainder of this 100 based segment
                tmp = curSegment % 100;

                if (tmp < 20)
                    curWord += " " + OneToNineteen[tmp];
                else
                {
                    curWord += " " + Tens[(int)tmp / 10]
                                + '-' + OneToNineteen[tmp % 10];
                }

                // always add the closing word as we HAVE something to build out
                curWord += " " + Block3Section[Block3Seq];

                // add the section above to the overall words
                FinalWords = curWord + FinalWords;
            }

            // to allow the next closing word for segment such as thousand, million, billion, etc
            Block3Seq++;
        }

        return FinalWords;
    }

これを試して...

        string[] ten = {"", "","Twenty","Thirty","Forty","Fifty",
        "Sixty","Seventy","Eighty","Ninety",};
        Console.WriteLine(" ---------------");
        int i = int.Parse(Console.ReadLine());
        if (i < 20)
        {
            Console.WriteLine(uptonineteen[i]);
        }
        else if (i < 100)
        {
            Console.WriteLine(((((i % 100) / 10) > 1) ? ten[((i % 100) / 10)] + ((i % 10) > 0 ? " " + uptonineteen[(i % 10)] : "") : " and " + uptonineteen[i % 100]));
        }
        else if (i <= 999)
        {
            object lenthree = uptonineteen[(i % 1000) / 100] + " hundred " + ((((i % 100) / 10) > 1) ? ten[((i % 100) / 10)] + ((i % 10) > 0 ? " " + uptonineteen[(i % 10)] : "") : " and " + uptonineteen[i % 100]);
            Console.WriteLine(lenthree);
        } 
        Console.ReadLine();
    }

string lenthree = ten[i / 100] + "hundred" + " " + 
    ((i % 100 > 0) ? "and" + " " + uptonineteen[i % 100] : "");

最後の 1000 は 100 のはずです。しかし、uptonineteen数字がいっぱいではないため、完全な数字を正しく入力することはできません。
