// get the first letter of a single character public String GetOneIndex (String OneIndexTxt) {if (Convert.ToChar (OneIndexTxt)> = 0 && Convert.ToChar (OneIndexTxt) <256) return OneIndexTxt; else {Encoding gb2312 = Encoding.GetEncoding ( " gb2312 "); byte [] unicodeBytes = Encoding.Unicode.GetBytes (OneIndexTxt); byte [] gb2312Bytes = Encoding.Convert (Encoding.Unicode, gb2312, unicodeBytes); return GetX (Convert.ToInt32 (String.Format (" {0 : D2} ", Convert.Toint16 (GB2312BYTES [0]) - 160) String.Format (" {0: D2} ", convert.TOINT16 (GB2312BYTES [1]) - 160)))));}}
