C# 汉字转拼音

一、简述

微软官方提供了一个类库包vsintlpack1.zip支持：

• 简繁体中文之间的转换
• 获取简体中文字符的常用属性比如拼音，多音字，同音字，笔画数
• 将小写的数字字符串格式化成简体中文，繁体中文，日文和韩文的大写数字字符串

二、安装使用

1）打开下载地址，解压安装 CHSPinYinConv.msi

2）打开默认安装目录：C:\Program Files (x86)\Microsoft Visual Studio International Pack\Simplified Chinese Pin-Yin Conversion Library\

3）在项目中，添加引用，ChnCharInfo.dll

三、源码

        {
            string shortPinYin = "";
            foreach (char c in inputTxt.Trim())
            {
                if (ChineseChar.IsValidChar(c))
                {
                    ChineseChar chineseChar = new ChineseChar(c);
                    shortPinYin += chineseChar.Pinyins[0].Substring(0, 1).ToUpper();
                    continue;
                }
