C#實現漢字轉換為拼音縮寫的代碼

本文提供的代碼是C#將漢字轉換為拼音縮寫的代碼，也是web頁面開發，具體實現如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace getPageValue
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write(GetPYString("中華人民共和國"));
        }
        public string GetPYString(string str)
        {
            string tempStr = "";
            foreach (char c in str)
            {
                if ((int)c >= 33 && (int)c <= 126)
                {//字母和符號原樣保留
                    tempStr += c.ToString();
                }
                else
                {//累加拼音聲母
                    tempStr += GetPYChar(c.ToString());
                }
            }
            return tempStr;
        }

        /// <summary>
        /// 取單個字符的拼音聲母
        /// </summary>
        /// <param name="c">要轉換的單個漢字</param>
        /// <returns>拼音聲母</returns>
        public string GetPYChar(string c)
        {
            byte[] array = new byte[2];
            array = System.Text.Encoding.Default.GetBytes(c);
            int i = (short)(array[0] - ) * 256 + ((short)(array[1] - ));

            if (i < 0xB0A1) return "*";
            if (i < 0xB0C5) return "a";
            if (i < 0xB2C1) return "b";
            if (i < 0xB4EE) return "c";
            if (i < 0xB6EA) return "d";
            if (i < 0xB7A2) return "e";
            if (i < 0xB8C1) return "f";
            if (i < 0xB9FE) return "g";
            if (i < 0xBBF7) return "h";
            if (i < 0xBFA6) return "g";
            if (i < 0xC0AC) return "k";
            if (i < 0xC2E8) return "l";
            if (i < 0xC4C3) return "m";
            if (i < 0xC5B6) return "n";
            if (i < 0xC5BE) return "o";
            if (i < 0xC6DA) return "p";
            if (i < 0xC8BB) return "q";
            if (i < 0xC8F6) return "r";
            if (i < 0xCBFA) return "s";
            if (i < 0xCDDA) return "t";
            if (i < 0xCEF4) return "w";
            if (i < 0xD1B9) return "x";
            if (i < 0xD4D1) return "y";
            if (i < 0xD7FA) return "z";
            return "*";
        }
    }
}
