C#实现将汉字转换为拼音

这篇文章仅微微涉及将汉字转换为拼音的实现方法，当然，能力有限，不能实现对声调的识别及显示！

页面设计

页面设计很简洁，一个输入框用来输入需要转换的文本，一个显示框用来展示转换后的文本。

代码实现部分

窗体代码

        private void txt_Chinese_TextChanged(object sender, EventArgs e){txt_PinYIn.Text = new PinYin().GetABC(txt_Chinese.Text);//调用拼音类的GetABC方法得到拼音字符串}

窗体内仅有一个当输入文本的字符发生改变时触发的事件，通过调用定义的方法来对输入文本进行解析。

PinYin类代码

首先定义好拼音区的编码数组：

    private static int[] getValue = new int[]{-20319,-20317,-20304,-20295,-20292,-20283,-20265,-20257,-20242,-20230,-20051,-20036,-20032,-20026,-20002,-19990,-19986,-19982,-19976,-19805,-19784,-19775,-19774,-19763,-19756,-19751,-19746,-19741,-19739,-19728,-19725,-19715,-19540,-19531,-19525,-19515,-19500,-19484,-19479,-19467,-19289,-19288,-19281,-19275,-19270,-19263,-19261,-19249,-19243,-19242,-19238,-19235,-19227,-19224,-19218,-19212,-19038,-19023,-19018,-19006,-19003,-18996,-18977,-18961,-18952,-18783,-18774,-18773,-18763,-18756,-18741,-18735,-18731,-18722,-18710,-18697,-18696,-18526,-18518,-18501,-18490,-18478,-18463,-18448,-18447,-18446,-18239,-18237,-18231,-18220,-18211,-18201,-18184,-18183, -18181,-18012,-17997,-17988,-17970,-17964,-17961,-17950,-17947,-17931,-17928,-17922,-17759,-17752,-17733,-17730,-17721,-17703,-17701,-17697,-17692,-17683,-17676,-17496,-17487,-17482,-17468,-17454,-17433,-17427,-17417,-17202,-17185,-16983,-16970,-16942,-16915,-16733,-16708,-16706,-16689,-16664,-16657,-16647,-16474,-16470,-16465,-16459,-16452,-16448,-16433,-16429,-16427,-16423,-16419,-16412,-16407,-16403,-16401,-16393,-16220,-16216,-16212,-16205,-16202,-16187,-16180,-16171,-16169,-16158,-16155,-15959,-15958,-15944,-15933,-15920,-15915,-15903,-15889,-15878,-15707,-15701,-15681,-15667,-15661,-15659,-15652,-15640,-15631,-15625,-15454,-15448,-15436,-15435,-15419,-15416,-15408,-15394,-15385,-15377,-15375,-15369,-15363,-15362,-15183,-15180,-15165,-15158,-15153,-15150,-15149,-15144,-15143,-15141,-15140,-15139,-15128,-15121,-15119,-15117,-15110,-15109,-14941,-14937,-14933,-14930,-14929,-14928,-14926,-14922,-14921,-14914,-14908,-14902,-14894,-14889,-14882,-14873,-14871,-14857,-14678,-14674,-14670,-14668,-14663,-14654,-14645,-14630,-14594,-14429,-14407,-14399,-14384,-14379,-14368,-14355,-14353,-14345,-14170,-14159,-14151,-14149,-14145,-14140,-14137,-14135,-14125,-14123,-14122,-14112,-14109,-14099,-14097,-14094,-14092,-14090,-14087,-14083,-13917,-13914,-13910,-13907,-13906,-13905,-13896,-13894,-13878,-13870,-13859,-13847,-13831,-13658,-13611,-13601,-13406,-13404,-13400,-13398,-13395,-13391,-13387,-13383,-13367,-13359,-13356,-13343,-13340,-13329,-13326,-13318,-13147,-13138,-13120,-13107,-13096,-13095,-13091,-13076,-13068,-13063,-13060,-12888,-12875,-12871,-12860,-12858,-12852,-12849,-12838,-12831,-12829,-12812,-12802,-12607,-12597,-12594,-12585,-12556,-12359,-12346,-12320,-12300,-12120,-12099,-12089,-12074,-12067,-12058,-12039,-11867,-11861,-11847,-11831,-11798,-11781,-11604,-11589,-11536,-11358,-11340,-11339,-11324,-11303,-11097,-11077,-11067,-11055,-11052,-11045,-11041,-11038,-11024,-11020,-11019,-11018,-11014,-10838,-10832,-10815,-10800,-10790,-10780,-10764,-10587,-10544,-10533,-10519,-10331,-10329,-10328,-10322,-10315,-10309,-10307,-10296,-10281,-10274,-10270,-10262,-10260,-10256,-10254};

紧接着定义拼音数组：

    private static string[] getStr = new string[]{"A","Ai","An","Ang","Ao","Ba","Bai","Ban","Bang","Bao","Bei","Ben","Beng","Bi","Bian","Biao","Bie","Bin","Bing","Bo","Bu","Ba","Cai","Can","Cang","Cao","Ce","Ceng","Cha","Chai","Chan","Chang","Chao","Che","Chen","Cheng","Chi","Chong","Chou","Chu","Chuai","Chuan","Chuang","Chui","Chun","Chuo","Ci","Cong","Cou","Cu","Cuan","Cui","Cun","Cuo","Da","Dai","Dan","Dang","Dao","De","Deng","Di","Dian","Diao","Die","Ding","Diu","Dong","Dou","Du","Duan","Dui","Dun","Duo","E","En","Er","Fa","Fan","Fang","Fei","Fen","Feng","Fo","Fou","Fu","Ga","Gai","Gan","Gang","Gao","Ge","Gei","Gen","Geng","Gong","Gou","Gu","Gua","Guai","Guan","Guang","Gui","Gun","Guo","Ha","Hai","Han","Hang","Hao","He","Hei","Hen","Heng","Hong","Hou","Hu","Hua","Huai","Huan","Huang","Hui","Hun","Huo","Ji","Jia","Jian","Jiang","Jiao","Jie","Jin","Jing","Jiong","Jiu","Ju","Juan","Jue","Jun","Ka","Kai","Kan","Kang","Kao","Ke","Ken","Keng","Kong","Kou","Ku","Kua","Kuai","Kuan","Kuang","Kui","Kun","Kuo","La","Lai","Lan","Lang","Lao","Le","Lei","Leng","Li","Lia","Lian","Liang","Liao","Lie","Lin","Ling","Liu","Long","Lou","Lu","Lv","Luan","Lue","Lun","Luo","Ma","Mai","Man","Mang","Mao","Me","Mei","Men","Meng","Mi","Mian","Miao","Mie","Min","Ming","Miu","Mo","Mou","Mu","Na","Nai","Nan","Nang","Nao","Ne","Nei","Nen","Neng","Ni","Nian","Niang","Niao","Nie","Nin","Ning","Niu","Nong","Nu","Nv","Nuan","Nue","Nuo","O","Ou","Pa","Pai","Pan","Pang","Pao","Pei","Pen","Peng","Pi","Pian","Piao","Pie","Pin","Ping","Po","Pu","Qi","Qia","Qian","Qiang","Qiao","Qie","Qin","Qing","Qiong","Qiu","Qu","Quan","Que","Qun","Ran","Rang","Rao","Re","Ren","Reng","Ri","Rong","Rou","Ru","Ruan","Rui","Run","Ruo","Sa","Sai","San","Sang","Sao","Se","Sen","Seng","Sha","Shai","Shan","Shang","Shao","She","Shen","Sheng","Shi","Shou","Shu","Shua","Shuai","Shuan","Shuang","Shui","Shun","Shuo","Si","Song","Sou","Su","Suan","Sui","Sun","Suo","Ta","Tai","Tan","Tang","Tao","Te","Teng","Ti","Tian","Tiao","Tie","Ting","Tong","Tou","Tu","Tuan","Tui","Tun","Tuo","Wa","Wai","Wan","Wang","Wei","Wen","Weng","Wo","Wu","Xi","Xia","Xian","Xiang","Xiao","Xie","Xin","Xing","Xiong","Xiu","Xu","Xuan","Xue","Xun","Ya","Yan","Yang","Yao","Ye","Yi","Yin","Ying","Yo","Yong","You","Yu","Yuan","Yue","Yun","Za", "Zai","Zan","Zang","Zao","Ze","Zei","Zen","Zeng","Zha","Zhai","Zhan","Zhang","Zhao","Zhe","Zhen","Zheng","Zhi","Zhong","Zhou","Zhu","Zhua","Zhuai","Zhuan","Zhuang","Zhui","Zhun","Zhuo","Zi","Zong","Zou","Zu","Zuan","Zui","Zun","Zuo"};

然后是汉字字符串转换为拼音字符串的方法，主要通过对比来拼凑汉字对应的拼音字符串：

    private string GetStr(char[] mChar,string pystr,Regex reg,byte[] arr){int asc = 0, M1 = 0, M2 = 0;for (int j = 0; j < mChar.Length; j++){if (reg.IsMatch(mChar[j].ToString()))              //如果输入的是汉字{arr = System.Text.Encoding.Default.GetBytes(mChar[j].ToString());M1 = (short)(arr[0]);M2 = (short)(arr[1]);asc = M1 * 256 + M2 - 65536;if (asc > 0 && asc < 160){pystr += mChar[j];}else{switch (asc){case -9254:pystr += "Zhen"; break;case -8985:pystr += "Qian"; break;case -5463:pystr += "Jia"; break;case -8274:pystr += "Ge"; break;case -5448:pystr += "Ga"; break;case -5447:pystr += "La"; break;case -4649:pystr += "Chen"; break;case -5436:pystr += "Mao"; break;case -5213:pystr += "Mao"; break;case -3597:pystr += "Die"; break;case -5659:pystr += "Tian"; break;default:for (int i = (getValue.Length - 1); i >= 0; i--){if (getValue[i] <= asc)        //判断汉字的拼音区编码是否在指定范围内{pystr += getStr[i];        //如果不超出范围则获取对应的拼音break;}}break;}}}else                                                //如果不是汉字{pystr += mChar[j].ToString();                   //如果不是汉字则返回}}return pystr;}

最后是用于调用的实现方法：

    /// <summary>/// 将汉字转换拼音的方法/// </summary>/// <param name="str">汉字字符串</param>/// <returns>拼音字符串</returns>public string GetABC(string str){Regex reg = new Regex("^[\u4e00-\u9fa5]$");        //通过正则表达式验证输入字符串是否为汉字byte[] arr = new byte[2];                          //定义字节数组string pystr = "";                                 //定义空字符串变量用于返回拼音字符串char[] mChar = str.ToCharArray();                  //获取汉字对应的字符数组return GetStr(mChar,pystr,reg,arr);                //返回获取到的汉字拼音字符串}

运行效果

结语

这个小程序主要是通过正则表达式筛选汉字字符，并查找对应的拼音字符串，构成并返回所生成的拼音文本。不足之处，望见谅。
