下载完毕后，进行解压，里面有7个msi文件，其中：CHSPinYinConv.msi就是汉字拼音相关的，CHTCHSConv.msi是进行 简体与繁体进行相互转换的，值安装这2个msi即可。安装完毕后，需要在VS里添加引用，分别引用：C:\Program Files\Microsoft Visual Studio International Pack\Simplified Chinese Pin-Yin Conversion Library下和C:\Program Files\Microsoft Visual Studio International Pack\Traditional Chinese to Simplified Chinese Conversion Library and Add-In Tool下的dll即可使用。

代码：

using Microsoft.International.Converters.PinYinConverter;
using Microsoft.International.Converters.TraditionalChineseToSimplifiedConverter;

        public static string GetPinyin(string str)
        {
            string r = string.Empty;
            foreach (char obj in str)
            {
                try
                {
                    ChineseChar chineseChar = new ChineseChar(obj);
                    string t = chineseChar.Pinyins[0].ToString();
                    r += t.Substring(0, t.Length - 1);
                }
                catch
                {
                    r += obj.ToString();
                }
            }
            return r;
        }

        public static string GetShortPinyin(string str)
        {
            string r = string.Empty;
            foreach (char obj in str)
            {
                try
                {
                    ChineseChar chineseChar = new ChineseChar(obj);
                    string t = chineseChar.Pinyins[0].ToString();
                    r += t.Substring(0, 1);
                }
                catch
                {
                    r += obj.ToString();
                }
            }
            return r;
        }

调用：
GetPinyin("全拼 瘦痩龙");
GetShortPinyin("首字符 瘦痩龙");
