Array.Contains忽略非間距組合字符，例如變音符

Question

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

此函數將返回false，因爲它嘗試檢查變音符單詞「rplay」而不是「replay」。我如何忽略非間距組合字符，如變音符號並返回true？

它如何才能反之亦然如下？

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

而且如何在這個函數中應用呢？

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

Answer 1

我寧願規範化搜索字符串，並在數組中搜索。

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)) { 
//... 
}
