问题描述
我需要将字符串中的重音符号替换为其对应的英文
I need to replace accents in the string to their english equivalents
例如
? = ae
? = oe
? = Oe
ü = ue
我知道从字符串中去除它们,但我不知道替换.
I know to strip of them from string but i was unaware about replacement.

推荐答案
如果您需要在较大的字符串上使用它,多次调用 Replace() 会很快变得效率低下.您最好逐个字符地重建字符串:
If you need to use this on larger strings, multiple calls to Replace() can get inefficient pretty quickly. You may be better off rebuilding your string character-by-character:
var map = new Dictionary<char, string>() { { '?', "ae" }, { '?', "oe" }, { 'ü', "ue" }, { '?', "Ae" }, { '?', "Oe" }, { 'ü', "Ue" }, { '?', "ss" } }; var res = germanText.Aggregate( new StringBuilder(), (sb, c) => map.TryGetValue(c, out var r) ? sb.Append(r) : sb.Append(c) ).ToString();
