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; }
