如题比如 我输入 “里斯” 也能查询到“李四”？

给楼主一个方法（网上找的），用来生成拼音
- C# code
/// <summary> /// 生成拼音简码 /// </summary> /// <param name="unicodeString">Unicode编码字符串</param> /// <returns>拼音简码:string</returns> public static string GetPinyinCode( string unicodeString) { int i = 0; ushort key = 0; string strResult = string .Empty; //创建两个不同的encoding对象 Encoding unicode = Encoding.Unicode; //创建GBK码对象 Encoding gbk = Encoding.GetEncoding(936); //将unicode字符串转换为字节 byte [] unicodeBytes = unicode.GetBytes(unicodeString); //再转化为GBK码 byte [] gbkBytes = Encoding.Convert(unicode, gbk, unicodeBytes); while (i < gbkBytes.Length) { //如果为数字/字母/其他ASCII符号 if (gbkBytes <= 127) { strResult = strResult + (char )gbkBytes; i++; } #region 否则生成汉字拼音简码,取拼音首字母 else { key = (ushort )(gbkBytes * 256 + gbkBytes[i + 1]); if (key >= '/uB0A1' && key <= '/uB0C4' ) { strResult = strResult + "A" ; } else if (key >= '/uB0C5' && key <= '/uB2C0' ) { strResult = strResult + "B" ; } else if (key >= '/uB2C1' && key <= '/uB4ED' ) { strResult = strResult + "C" ; } else if (key >= '/uB4EE' && key <= '/uB6E9' ) { strResult = strResult + "D" ; } else if (key >= '/uB6EA' && key <= '/uB7A1' ) { strResult = strResult + "E" ; } else if (key >= '/uB7A2' && key <= '/uB8C0' ) { strResult = strResult + "F" ; } else if (key >= '/uB8C1' && key <= '/uB9FD' ) { strResult = strResult + "G" ; } else if (key >= '/uB9FE' && key <= '/uBBF6' ) { strResult = strResult + "H" ; } else if (key >= '/uBBF7' && key <= '/uBFA5' ) { strResult = strResult + "J" ; } else if (key >= '/uBFA6' && key <= '/uC0AB' ) { strResult = strResult + "K" ; } else if (key >= '/uC0AC' && key <= '/uC2E7' ) { strResult = strResult + "L" ; } else if (key >= '/uC2E8' && key <= '/uC4C2' ) { strResult = strResult + "M" ; } else if (key >= '/uC4C3' && key <= '/uC5B5' ) { strResult = strResult + "N" ; } else if (key >= '/uC5B6' && key <= '/uC5BD' ) { strResult = strResult + "O" ; } else if (key >= '/uC5BE' && key <= '/uC6D9' ) { strResult = strResult + "P" ; } else if (key >= '/uC6DA' && key <= '/uC8BA' ) { strResult = strResult + "Q" ; } else if (key >= '/uC8BB' && key <= '/uC8F5' ) { strResult = strResult + "R" ; } else if (key >= '/uC8F6' && key <= '/uCBF9' ) { strResult = strResult + "S" ; } else if (key >= '/uCBFA' && key <= '/uCDD9' ) { strResult = strResult + "T" ; } else if (key >= '/uCDDA' && key <= '/uCEF3' ) { strResult = strResult + "W" ; } else if (key >= '/uCEF4' && key <= '/uD188' ) { strResult = strResult + "X" ; } else if (key >= '/uD1B9' && key <= '/uD4D0' ) { strResult = strResult + "Y" ; } else if (key >= '/uD4D1' && key <= '/uD7F9' ) { strResult = strResult + "Z" ; } else { strResult = strResult + "?" ; } i = i + 2; } #endregion }//end while return strResult; }
