C# 真正完美的 汉字转拼音
网上有很多说自己整理的汉字转拼音是完美的,但使用后才发现都是半吊的瓶子,问题多多。
常见的生僻字,或多音字识别,转换后简直让人感觉可怕。
主流的转换有三种:hash匹配,Npinyin,微软PinYinConverter。
但单用这三个,都没法做到完美,为什么没人考虑融合呢?
我的方案:Npinyin+微软PinYinConverter(首选Npinyin)
微软PinYinConverter
为什么:微软PinYinConverter很强大,但在多音字面前,犯了传统的错误,按拼音字母排序。如【强】微软居然优先【jiang】而不是】【qiang】
所以不能优选 PinYinConverter。
Npinyin
很人性,很不错的第三方库,在传统多音字前优先使用率较高的,但在生僻字面前有点无法转换。(GetInitials(strChinese) 有Bug 如【洺】无法识别,但GetPinyin可以正常转换。)
总结:优先Npinyin 翻译失败的使用微软PinYinConverter。目测完美。
上代码:
public class PingYinHelper { private static Encoding gb2312 = Encoding.GetEncoding("GB2312"); /// <summary> /// 汉字转全拼 /// </summary> /// <param name="strChinese"></param> /// <returns></returns> public static string ConvertToAllSpell(string strChinese) { try { if (strChinese.Length != 0) { StringBuilder fullSpell = new StringBuilder(); for (int i = 0; i < strChinese.Length; i++) { var chr = strChinese[i]; fullSpell.Append(GetSpell(chr)); } return fullSpell.ToString().ToUpper(); } } catch (Exception e) { Console.WriteLine("全拼转化出错!" + e.Message); } return string.Empty; } /// <summary> /// 汉字转首字母 /// </summary> /// <param name="strChinese"></param> /// <returns></returns> public static string GetFirstSpell(string strChinese) { //NPinyin.Pinyin.GetInitials(strChinese) 有Bug 洺无法识别 //return NPinyin.Pinyin.GetInitials(strChinese); try { if (strChinese.Length != 0) { StringBuilder fullSpell = new StringBuilder(); for (int i = 0; i < strChinese.Length; i++) { var chr = strChinese[i]; fullSpell.Append(GetSpell(chr)[0]); } return fullSpell.ToString().ToUpper(); } } catch (Exception e) { Console.WriteLine("首字母转化出错!" + e.Message); } return string.Empty; } private static string GetSpell(char chr) { var coverchr = NPinyin.Pinyin.GetPinyin(chr); bool isChineses = ChineseChar.IsValidChar(coverchr[0]); if (isChineses) { ChineseChar chineseChar = new ChineseChar(coverchr[0]); foreach (string value in chineseChar.Pinyins) { if (!string.IsNullOrEmpty(value)) { return value.Remove(value.Length - 1, 1); } } } return coverchr; } }
抽了几个常见错字和姓名
测试如下:
[TestMethod] public void PingyinTest() { Dictionary<string, Tuple<string, string>> dict = new Dictionary<string, Tuple<string, string>>() { {"梅钰", new Tuple<string,string>( "meiyu","MY")}, {"张洺", new Tuple<string,string>( "zhangming","ZM")}, {"王玥", new Tuple<string,string>( "wangyue","WY")}, {"王思琪", new Tuple<string,string>( "wangsiqi","WSQ")}, {"董云强", new Tuple<string,string>( "dongyunqiang","DYQ")}, {"宋红培", new Tuple<string,string>( "songhongpei","SHP")}, {"石磊", new Tuple<string,string>( "shilei","SL")}, }; foreach (var keyval in dict) { var name = keyval.Key; var spell1 = keyval.Value.Item1; var spell2 = keyval.Value.Item2; var val = ChineseSpell.ConvertToAllSpell(name).TrimAll(); val = FlexLogicFramework.Library.CommonLib.PingYinHelper.ConvertToAllSpell(name) .TrimAll().ToLower(); Assert.IsTrue(val == spell1, "转换错误"); val = FlexLogicFramework.Library.CommonLib.ChineseSpell.GetFirstSpell(name).TrimAll(); val = FlexLogicFramework.Library.CommonLib.PingYinHelper.GetFirstSpell(name).TrimAll(); Assert.IsTrue(val == spell2, "转换错误"); } }
