下载并引入两个dll文件  和  

　　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
     
       pinyinDic = JsonConvert.DeserializeObject
      
       
        >(sr.ReadToEnd());            string name = "薄露露";            Console.WriteLine(name+PinYinHelper.ConvertToAllSpell(name, pinyinDic).ToLower());            Console.ReadKey();        }

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。
