字符串替换c[重复]中的音调符号

似乎你想去掉音调符号,留下基本字符。我建议 Ben Lings's solution 在这里:

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

编辑:小问题!它不适用于_。结果是:

SĐCZ sđccz

斯基特 mentioned the following code on a newsgroup …

static string RemoveAccents (string input)
{
    string normalized = input.Normalize(NormalizationForm.FormKD);
    Encoding removal = Encoding.GetEncoding(Encoding.ASCII.CodePage,
                                            new EncoderReplacementFallback(""),
                                            new DecoderReplacementFallback(""));
    byte[] bytes = removal.GetBytes(normalized);
    return Encoding.ASCII.GetString(bytes);
}

也许我疯了,但我只是跑了以下几步…

Dim Input As String = "ŠĐĆŽ-šđčćž"
Dim Builder As New StringBuilder()

For Each Chr As Char In Input
    Builder.Append(Chr)
Next

Console.Write(Builder.ToString())

结果是 SDCZ-sdccz

字典是解决这一问题的合理方法…

Dictionary<char, char> AccentEquivelants = new Dictionary<char, char>();
AccentEquivelants.Add('Å ', 's');
//...add other equivelents

string inputstring = "";
StringBuilder FixedString = new StringBuilder(inputstring);
for (int i = 0; i < FixedString.Length; i++)
    if (AccentEquivelants.ContainsKey(FixedString[i]))
        FixedString[i] = AccentEquivelants[FixedString[i]];
return FixedString.ToString();

在执行这样的字符串操作时,需要使用StringBuilder,因为C中的字符串是不可变的,因此一次更改一个字符将在内存中创建多个字符串对象,而StringBuilder是可变的,没有这个缺点。
