看看如何使用C# [ ^ ].

尝试使用此方法创建一个NumberToWordsConvertor类:

Try this make a class NumberToWordsConvertor:

class NumberToWordsConvertor
    {

            // Single-digit and small number names
            private string[] _smallNumbers = new string[] { "Zero", "One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen" };

            // Tens number names from twenty upwards
            private string[] _tens = new string[] { "", "", "Twenty", "Thirty", "Forty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety" };

            // Scale number names for use during recombination
            private string[] _scaleNumbers = new string[] { "", "Thousand", "Million", "Billion" };



            // Converts an integer value into English words
            public string NumberToWords(int number)
            {
                // Zero rule
                if (number == 0)
                    return _smallNumbers[0];

                // Array to hold four three-digit groups
                int[] digitGroups = new int[4];

                // Ensure a positive number to extract from
                int positive = Math.Abs(number);

                // Extract the three-digit groups
                for (int i = 0; i < 4; i++)
                {
                    digitGroups[i] = positive % 1000;
                    positive /= 1000;
                }

                // Convert each three-digit group to words
                string[] groupText = new string[4];

                for (int i = 0; i < 4; i++)
                    groupText[i] = ThreeDigitGroupToWords(digitGroups[i]);

                // Recombine the three-digit groups
                string combined = groupText[0];
                bool appendAnd;

                // Determine whether an 'and' is needed
                appendAnd = (digitGroups[0] > 0) && (digitGroups[0] < 100);

                // Process the remaining groups in turn, smallest to largest
                for (int i = 1; i < 4; i++)
                {
                    // Only add non-zero items
                    if (digitGroups[i] != 0)
                    {
                        // Build the string to add as a prefix
                        string prefix = groupText[i] + " " + _scaleNumbers[i];

                        if (combined.Length != 0)
                            prefix += appendAnd ? "" : ", ";

                        // Opportunity to add 'and' is ended
                        appendAnd = false;

                        // Add the three-digit group to the combined string
                        combined = prefix + combined;
                    }
                }

                // Negative rule
                if (number < 0)
                    combined = "Negative " + combined;

                return combined;
            }



            // Converts a three-digit group into English words
            private string ThreeDigitGroupToWords(int threeDigits)
            {
                // Initialise the return text
                string groupText = "";

                // Determine the hundreds and the remainder
                int hundreds = threeDigits / 100;
                int tensUnits = threeDigits % 100;

                // Hundreds rules
                if (hundreds != 0)
                {
                    groupText += _smallNumbers[hundreds] + " Hundred";

                    if (tensUnits != 0)
                        groupText += "";
                }

                // Determine the tens and units
                int tens = tensUnits / 10;
                int units = tensUnits % 10;

                // Tens rules
                if (tens >= 2)
                {
                    groupText += _tens[tens];
                    if (units != 0)
                        groupText += "" + _smallNumbers[units];
                }
                else if (tensUnits != 0)
                    groupText += _smallNumbers[tensUnits];

                return groupText;
            }

然后像这样使用它:

then use it like this:

NumberToWordsConvertor numword = new NumberToWordsConvertor();

string marksinwords = numword.NumberToWords(85);
