ASP.NET Core使用微软官方类库实现汉字转拼音

一、NuGet包

拼音：Install-Package PinYinConverterCore

简体-繁体互转：Install-Package TraditionalChineseToSimplifiedConverter

二、C#代码

    class Program
    {
     
        static void Main(string[] args)
        {

            string Name= "刘大大";

            Console.WriteLine($"{Name}\n全拼：{GetPinyin(Name)}，\n首拼：{GetFirstPinyin(Name)},\n繁体字：{GetTraditional(Name)},\n简体字：{GetSimplified(GetTraditional(Name))}");


            Console.ReadKey();
        }
