取汉字/中文的拼音首字母

最近在项目中遇到个问题，要将人名前加拼音首字母，方便查找。

 

我在这方法中取得了一级和二级所有字库，也对常见的多音字姓氏做了修改。

传入参数是姓名，返回拼音首字母+姓名，例如：传入"张扬"，返回"ZY张扬"

 

命名空间：

using System.Text.RegularExpressions;

 

方法如下：

        /// <summary>
        ///  获得名字首字母拼音
        /// </summary>
        /// <param name="ChineseStr"></param>
        protected string GB2Spell(string ChineseStr)
        {
            try
            {
                //获得首字母
                Regex CheckStr = new Regex("[\u4e00-\u9fa5]");
                string Capstr = "";
                byte[] ZW = new byte[2];
                string CharStr, ChinaStr = "";

                if (CheckStr.IsMatch(ChineseStr))//如果是汉字
                {
                    for (int i = 0; i <= ChineseStr.Length - 1; i++)
                    {
                        //对常见的多音字姓氏特殊处理
                        string firstName = ChineseStr.Substring(0, 1).ToString();//单姓氏
                        if (i == 0 && firstName == "仇") { Capstr = "Q"; continue; }
                        if (i == 0 && firstName == "重") { Capstr = "C"; continue; }
                        if (i == 0 && firstName == "区") { Capstr = "O"; continue; }
                        if (i == 0 && firstName == "秘") { Capstr = "B"; continue; }
                        if (i == 0 && firstName == "解") { Capstr = "X"; continue; }
                        if (i == 0 && firstName == "折") { Capstr = "S"; continue; }
                        if (i == 0 && firstName == "单") { Capstr = "S"; continue; }
                        if (i == 0 && firstName == "翟") { Capstr = "Z"; continue; }
                        if (i == 0 && firstName == "查") { Capstr = "Z"; continue; }
                        if (i == 0 && firstName == "曾") { Capstr = "Z"; continue; }

                        string firstName2 = ChineseStr.Substring(0, 2).ToString();//多姓氏
                        if (i == 0 && firstName == "万俟") { Capstr = "MQ"; i++; continue; }
                        if (i == 0 && firstName == "尉迟") { Capstr = "YC"; i++; continue; }

                        CharStr = ChineseStr.Substring(i, 1).ToString();

                        if (i == 0 && ZW.Length != 2)//如果第一个字符不是中文，则不需要加首字母拼音    
                            break;

ps:对于二级字库中的汉字，有些字符也是取得不正确，例如:茜玥芮溍珏芸褚赟瓛钰.百度了很长时间也没找到正确的二级字库.所以在程序中遇到不常用的字符也只能写死处理。
