c#汉字转拼音首字母全拼支持多音字

1.首先在NuGet安装pingyinConverter

2.下载-安装-引用ChineseChar.dll到项目中

官网了解：http://www.microsoft.com/zh-cn/download/confirmation.aspx?id=15251

3.直接上代码了

 public class PinYinConverterHelp
     {
         public static PingYinModel GetTotalPingYin(string str)
         {
             var chs = str.ToCharArray();
             //记录每个汉字的全拼
             Dictionary<int, List<string>> totalPingYins = new Dictionary<int, List<string>>();
             for (int i = ; i < chs.Length; i++)
             {
                 var pinyins = new List<string>();
                 var ch = chs[i];
                 //是否是有效的汉字
                 if (ChineseChar.IsValidChar(ch))
                 {
                     ChineseChar cc = new ChineseChar(ch);
                     pinyins = cc.Pinyins.Where(p => !string.IsNullOrWhiteSpace(p)).ToList();
                 }
                 else
                 {
                     pinyins.Add(ch.ToString());
                 }

                 //去除声调，转小写
                 pinyins = pinyins.ConvertAll(p => Regex.Replace(p, @"\d", "").ToLower());
