VB.net中文字符串转拼音

从NuGet上发现一个很好用的包可以实现该效果

这个包可以直接把单个汉子转换成拼音字符串,于是自己写了个函数实现对整个字符串的拼音转换

        ft.VCharType = Pinyin4net.Format.HanyuPinyinVCharType.WITH_V    '使用v来表示韵母u,女=nv
        ft.CaseType = Pinyin4net.Format.HanyuPinyinCaseType.LOWERCASE   '使用小写
        ft.ToneType = Pinyin4net.Format.HanyuPinyinToneType.WITHOUT_TONE    '不带声标,否则会带数字第几声,例如:牛=niu2
        For Each c As Char In charArray
            pinyin &= Pinyin4net.PinyinHelper.ToHanyuPinyinStringArray(c, ft)(0)
        Next
        Return pinyin
    End Function
