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;
}
