C#汉字转拼音

新老客户大回馈,云服务器低至5折

  下载并引入两个dll文件 NPinyin.dll 和 ChnCharInfo.dll 

  其实这两个dll 任何一个都可以实现汉字转拼音,然而 NPinyin.dll 收录的汉字并不全,但是很人性化,能识别一些常用的汉字。ChnCharInfo.dll 是微软的很全但是不人性化。另外本套代码外有一个自己维护的个别汉字文件,例如一些多音字姓氏。

  本程序的使用场景是姓名转拼音,所以先判断第一个汉字是否在自己维护的拼音库中存在,如果存在者优先使用这个库中汉字所对应的拼音,如果不存在者优先使用NPinyin库中转化拼音的方法,转化失败再使用微软提供的ChnCharInfo中转拼音的方法。

  Main函数

 static void Main(string[] args)
        {
            string path = @"PinYinDic.txt";
            StreamReader sr = new StreamReader(path, Encoding.Default);
            Dictionary<char, string> pinyinDic = JsonConvert.DeserializeObject<Dictionary<char, string>>(sr.ReadToEnd());

            string name = "薄露露";
            Console.WriteLine(name+PinYinHelper.ConvertToAllSpell(name, pinyinDic).ToLower());
            Console.ReadKey();
        }
PinYinHelper类
public class PinYinHelper
    {
        private static Encoding gb2312 = Encoding.GetEncoding("GB2312");

接下来是本程序维护的 PinYinDic.txt,该文件放在"\bin\Debug"目录下,当然也可以不使用。
