我如何在 .NET 中替换口音(德语)

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.

如果您有任何建议，请告诉我.我正在用 C# 编码

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();
