42 private static string getPinYin(string text)
43    ...{
44        char pinyin;
45        byte[] array;
46        System.Text.StringBuilder sb = new System.Text.StringBuilder(text.Length);

78                                                            if (i < 0xC2E8) pinyin = 'l';
79                                                            else
80                                                                if (i < 0xC4C3) pinyin = 'm';
81                                                                else

87                                                                            else
88                                                                                if (i < 0xC8BB) pinyin = 'q';
89                                                                                else
90                                                                                    if (i < 0xC8F6) pinyin = 'r';
91                                                                                    else
92                                                                                        if (i < 0xCBFA) pinyin = 's';
93                                                                                        else
94                                                                                            if (i < 0xCDDA) pinyin = 't';
95                                                                                            else
96                                                                                                if (i < 0xCEF4) pinyin = 'w';
97                                                                                                else
98                                                                                                    if (i < 0xD1B9) pinyin = 'x';
99                                                                                                    else
100                                                                                                        if (i < 0xD4D1) pinyin = 'y';
101                                                                                                        else
102                                                                                                            if (i < 0xD7FA) pinyin = 'z';
103            }
104
105            sb.Append(pinyin);
106        }
107
108        return sb.ToString();
109    }上面的代码兼容了数字和字母，我想不兼容数字和字母，比如“好不啊aa哈”只能通过“hbah”查询即可

Answer 2

这也太强了把...这么多if else  在sb.Append(pinyin);前家 
                                                                                                
                else
                {
                    continue;
                }
                sb.Append(pinyin);
