CodeGo.net>有库将数字拼音转换为带有音标的拼音吗？

只是想知道是否有人知道可以将汉语拼音转换为带有声调的类库的类库,例如nin2 hao3 ma到nínhǎoma.它将类似于this answer,但希望使用.NET框架.

解决方法:

这是我将@ Greg-Hewgill python algorithm移植到C#的过程.到目前为止,我还没有遇到任何问题.

public static string ConvertNumericalPinYinToAccented(string input)
    {
        Dictionary<int, string> PinyinToneMark = new Dictionary<int, string>
        {
            {0, "aoeiuv\u00fc"},
            {1, "\u0101\u014d\u0113\u012b\u016b\u01d6\u01d6"},
            {2, "\u00e1\u00f3\u00e9\u00ed\u00fa\u01d8\u01d8"},
            {3, "\u01ce\u01d2\u011b\u01d0\u01d4\u01da\u01da"},
            {4, "\u00e0\u00f2\u00e8\u00ec\u00f9\u01dc\u01dc"}
        };

        string[] words = input.Split(' ');
        string accented = "";
        string t = "";
        foreach (string pinyin in words)
        {
            foreach (char c in pinyin)
            {
                if (c >= 'a' && c <= 'z')
                {
                    t += c;
                }
                else if (c == ':')
                {
                    if (t[t.Length - 1] == 'u')
                    {
                        t = t.Substring(0, t.Length - 2) + "\u00fc";
                    }
                }
                else
                {
                    if (c >= '0' && c <= '5')
                    {
                        int tone = (int)Char.GetNumericValue(c) % 5;

                        if (tone != 0)
                        {
                            Match match = Regex.Match(t, "[aoeiuv\u00fc]+");
                            if (!match.Success)
                            {
                                t += c;
                            }
                            else if (match.Groups[0].Length == 1)
                            {
                                t = t.Substring(0, match.Groups[0].Index) +
                                    PinyinToneMark[tone][PinyinToneMark[0].IndexOf(match.Groups[0].Value[0])]
                                    + t.Substring(match.Groups[0].Index + match.Groups[0].Length);
                            }
                            else
                            {
                                if (t.Contains("a"))
                                {
                                    t = t.Replace("a", PinyinToneMark[tone][0].ToString());
                                }
                                else if (t.Contains("o"))
                                {
                                    t = t.Replace("o", PinyinToneMark[tone][1].ToString());
                                }
                                else if (t.Contains("e"))
                                {
                                    t = t.Replace("e", PinyinToneMark[tone][2].ToString());
                                }
                                else if (t.Contains("ui"))
                                {
                                    t = t.Replace("i", PinyinToneMark[tone][3].ToString());
                                }
                                else if (t.Contains("iu"))
                                {
