按文化排序未按预期工作

Question

为什么“Ū”排在第一位而不是 "U"？

    CultureInfo ci = CultureInfo.GetCultureInfo("lt-LT");
    bool ignoreCase = true; //whether comparison should be case-sensitive
    StringComparer comp = StringComparer.Create(ci, ignoreCase);
    string[] unordered = { "Za", "Žb", "Ūa", "Ub" };
    var ordered = unordered.OrderBy(s => s, comp);

订购结果： Ūa Ub 杂兹布

应该是：Ub Ūa Za Žb

这是立陶宛字母的顺序。 https://www.assorti.lt/userfiles/uploader/no/norvegiska-lietuviska-delione-abecele-maxi-3-7-m-vaikams-larsen.jpg

我刚刚为您的问题做了一个（有限的）解决方案。这不是优化的，但它可以给出如何解决它的想法。我创建了一个 LithuanianString class 仅用于封装您的字符串。 class 实现 IComparable 以便能够对 LithuanianString 的列表进行排序。

这可能是 class:

public class LithuanianString : IComparable<LithuanianString>
{

    const string UpperAlphabet = "AĄBCČDEĘĖFGHIĮYJKLMNOPRSŠTUŲŪVZŽ";
    const string LowerAlphabet = "aąbcčdeęėfghiįyjklmnoprsštuųūvzž";
    public string String;

    public LithuanianString(string inputString)
    {
        this.String = inputString;
    }

    public int CompareTo(LithuanianString other)
    {
        var maxIndex = this.String.Length <= other.String.Length ? this.String.Length : other.String.Length;
        for (var i = 0; i < maxIndex; i++)
        {
            //We make the method non case sensitive
            var indexOfThis = LowerAlphabet.Contains(this.String[i])
                ? LowerAlphabet.IndexOf(this.String[i])
                : UpperAlphabet.IndexOf(this.String[i]);

            var indexOfOther = LowerAlphabet.Contains(other.String[i])
                ? LowerAlphabet.IndexOf(other.String[i])
                : UpperAlphabet.IndexOf(other.String[i]);

            if (indexOfOther != indexOfThis)
                return indexOfThis - indexOfOther;
        }
        return this.String.Length - other.String.Length;
    }
}

这是我制作的示例：

static void Main(string[] args)
    {
        string[] unordered = { "Za", "Žb", "Ūa", "Ub" };

        //Create a list of lithuanian string from your array
        var lithuanianStringList = (from unorderedString in unordered
            select new LithuanianString(unorderedString)).ToList();
        //Sort it 
        lithuanianStringList.Sort();

        //Display it
        Console.WriteLine(Environment.NewLine + "My Comparison");
        lithuanianStringList.ForEach(c => Console.WriteLine(c.String));
    }

输出是预期的：

Ub Ūa Za Žb

此 class 允许仅通过替换开头定义的两个常量中的字符来创建自定义字母表。
