C#中获得汉字的首拼音(简化版)

利用汉字在计算机里面的编码来得到汉字的首拼音：

static public string GetChineseSpell(string strText)
{
    int len = strText.Length;
    string myStr = "";
    for(int i=0;i<len;i++)
        myStr += getSpell(strText.Substring(i,1));
    return myStr;
}

static public string getSpell(string cnChar)
{
    byte[] arrCN = Encoding.Default.GetBytes(cnChar);
    if(arrCN.Length > 1)
    {
        int area = (short)arrCN[0];
        int pos = (short)arrCN[1];
        int code = (area<<8) + pos;
        int[] areacode = {45217,45253,45761,46318,46826,47010,47297,47614,48119,48119,49062,49324,49896,50371,50614,50622,50906,51387,51446,52218,52698,52698,52698,52980,53689,54481};
        for(int i=0;i<26;i++)
        {
            int max = 55290;
            if(i != 25) 
                max = areacode[i+1];
            if(areacode[i]<=code && code<max)
                return Encoding.Default.GetString(new byte[]{(byte)(65+i)});
        }
        return "*";
    }
    else 
        return cnChar;
}

这个方法目前对一些生僻字无法解码,有待修改...
