Error message

找不到拼音

What it means

ZhuyinHelper.GetZhuyin(string) converts a pinyin syllable into Bopomofo (注音). Identical guard pattern to Chaoyin (error [0]): it throws this bare Exception ONLY for null/empty pinyin input; it returns null (not throws) for a valid-but-unmapped pinyin. So this throw means the caller passed no pinyin, not an unknown one.

Solutions

1. Filter empty/whitespace strings out of the pinyin list before calling zhuyin generation.
2. Guard each pinyin with string.IsNullOrEmpty(p) and skip when blank.
3. Fix upstream pinyin resolution so empty pinyins never reach the generator.

Example fix

// before
var zy = ZhuyinHelper.GetZhuyin(p);
// after
if (string.IsNullOrEmpty(p)) continue;
var zy = ZhuyinHelper.GetZhuyin(p);

if (string.IsNullOrEmpty(pinyin)) continue;
var zy = ZhuyinHelper.GetZhuyin(pinyin);

try { var zy = ZhuyinHelper.GetZhuyin(p); }
catch (Exception ex) when (ex.Message == "找不到拼音") { /* skip empty pinyin */ }

When it happens

Trigger: Calling ZhuyinHelper.GetZhuyin(null) or GetZhuyin(""); or indirectly via GetZhuyin(IList<string>) (line 92) when the list contains an empty pinyin string.

Common situations: Zhuyin code generation on a word whose pinyin could not be resolved upstream, so an empty pinyin was passed in; an importer emitted blank pinyin codes that reach the zhuyin generator.
