c# - 如何将土耳其字符转换为字符串中的英文字符？

Question

字符串 strTurkish = "ÜST";

如何将 strTurkish 的价值设为“UST”？

Answer 1

您可以使用以下方法来解决您的问题。其他方法不能正确转换“土耳其语小写 I (\u0131)”。

public static string RemoveDiacritics(string text)
{
    Encoding srcEncoding = Encoding.UTF8;
    Encoding destEncoding = Encoding.GetEncoding(1252); // Latin alphabet

    text = destEncoding.GetString(Encoding.Convert(srcEncoding, destEncoding, srcEncoding.GetBytes(text)));

    string normalizedString = text.Normalize(NormalizationForm.FormD);
    StringBuilder result = new StringBuilder();

    for (int i = 0; i < normalizedString.Length; i++)
    {
        if (!CharUnicodeInfo.GetUnicodeCategory(normalizedString[i]).Equals(UnicodeCategory.NonSpacingMark))
        {
            result.Append(normalizedString[i]);
        }
    }

    return result.ToString();
}

Answer 2

var text = "ÜST";
var unaccentedText  = String.Join("", text.Normalize(NormalizationForm.FormD)
        .Where(c => char.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark));

Answer 3

我不是这类事情的专家，但我认为你可以string.Normalize通过分解值然后有效地删除非 ASCII 字符来做到这一点：

using System;
using System.Linq;
using System.Text;

class Test
{
    static void Main()
    {
        string text = "\u00DCST";
        string normalized = text.Normalize(NormalizationForm.FormD);
        string asciiOnly = new string(normalized.Where(c => c < 128).ToArray());
        Console.WriteLine(asciiOnly);
    }    
}

不过，在某些情况下，这完全有可能会造成可怕的事情。

Answer 4

public string TurkishCharacterToEnglish(string text)
{
    char[] turkishChars = {'ı', 'ğ', 'İ', 'Ğ', 'ç', 'Ç', 'ş', 'Ş', 'ö', 'Ö', 'ü', 'Ü'};
    char[] englishChars = {'i', 'g', 'I', 'G', 'c', 'C', 's', 'S', 'o', 'O', 'u', 'U'};
    
    // Match chars
    for (int i = 0; i < turkishChars.Length; i++)
        text = text.Replace(turkishChars[i], englishChars[i]);

    return text;
}

Answer 5

这不是一个需要通用解决方案的问题。众所周知，土耳其字母表中只有 12 个特殊字符需要规范化。这些是 ı,İ,ö,Ö,ç,Ç,ü,Ü,ğ,Ğ,ş,Ş。您可以编写 12 条规则来替换它们的英文对应规则：i,I,o,O,c,C,u,U,g,G,s,S。

Answer 6

Public Function Ceng(ByVal _String As String) As String
    Dim Source As String = "ığüşöçĞÜŞİÖÇ"
    Dim Destination As String = "igusocGUSIOC"
    For i As Integer = 0 To Source.Length - 1
        _String = _String.Replace(Source(i), Destination(i))
    Next
    Return _String
End Function

    public static string TurkishChrToEnglishChr(this string text)
    {
        if (string.IsNullOrEmpty(text)) return text;

        Dictionary<char, char> TurkishChToEnglishChDic = new Dictionary<char, char>()
        {
            {'ç','c'},
            {'Ç','C'},
            {'ğ','g'},
            {'Ğ','G'},
            {'ı','i'},
            {'İ','I'},
            {'ş','s'},
            {'Ş','S'},
            {'ö','o'},
            {'Ö','O'},
            {'ü','u'},
            {'Ü','U'}
        };

        return text.Aggregate(new StringBuilder(), (sb, chr) =>
        {
            if (TurkishChToEnglishChDic.ContainsKey(chr))
                sb.Append(TurkishChToEnglishChDic[chr]);
            else
                sb.Append(chr);

            return sb;
        }).ToString();
    }
