c# - Array.Contains 忽略非间距组合字符，例如变音符号

Question

string[] myArray= { "replay", "answer" };
if (myArray.Contains("rểplay")) {
//...
}

此函数将返回 false，因为它尝试检查变音符号“rểplay”而不是“replay”。如何忽略非间距组合字符，例如变音符号并返回 true？

反之亦然，如下所示？

string[] myArray= { "rểplay", "answer" };
if (myArray.Contains("replay")) {
//...
}

以及如何在此功能中应用？

var ix = Array.FindIndex(myKeys, p => p.Equals(wordIn, StringComparison.CurrentCultureIgnoreCase));
wordOut = myKeys[ix];
return true;

Answer 1

我宁愿规范化搜索字符串并在数组中搜索。

using System.Globalization;

string input = "rểplay";
string decomposed = input.Normalize(NormalizationForm.FormD);
char[] filtered = decomposed
    .Where(c => char.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark)
    .ToArray();
string newString = new String(filtered);

string[] myArray= { "replay", "answer" };
if (myArray.Contains(newString)) {
//...
}
