任何将数字拼音转换为带声调标记的拼音的库

这是我将@Greg Hewgill python算法移植到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";
                    }

                        if (tone != 0)
                        {
                            Match match = Regex.Match(t, "[aoeiuv'u00fc]+");
                            if (!match.Success)

                                    PinyinToneMark[tone][PinyinToneMark[0].IndexOf(match.Groups[0].Value[0])]
                                    + t.Substring(match.Groups[0].Index + match.Groups[0].Length);
                            }
                            else
                            {

                                {
                                    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"))
                                {
                                    t = t.Replace("u", PinyinToneMark[tone][4].ToString());
                                }
                                else
                                {
                                    t += "!";
                                }
                            }
                        }
                    }
                    accented += t;
                    t = "";
                }
            }
            accented += t + " ";
        }
        accented = accented.TrimEnd();
        return accented;
    }

我使用过Microsoft Visual Studio International Pack。

这是1.0版本。以及功能包2.0。

希望能帮助你！

我认为这条线是

t = t.Substring(0, t.Length - 2) + "'u00fc";

应该是这个

t = t.Substring(0, t.Length - 1) + "'u00fc";
