IComparer 不对简单的 a b c 进行排序？

Question

我有我的字符串 class 设置并制作了一个 StringComparer class 它实现了 IComparer 并且想在 Rank 上对我的字符串数组进行排序并显示它。目前它显示：

a,x,c

当我按 Rank 排序时。为什么会这样？它应该显示：

a,c,x

还是字母表一夜之间变了？

class Program
{
    static void Main(string[] args)
    {
        String[] strings = { new String() { Name = "1123", Rank = "a" }, new String() { Name = "3123", Rank = "x" }, new String() { Name = "3134311", Rank = "c" } };
        StringComparer comparer = new StringComparer();

        comparer.SortBy = StringComparer.CompareField.Name;
        Array.Sort(strings, comparer);

        foreach (String s in strings)
        {
            Console.WriteLine(s.Name);
        }
        comparer.SortBy = StringComparer.CompareField.Rank;
        Array.Sort(strings, comparer);

        foreach (String s in strings)
        {
            Console.WriteLine(s.Rank);
        }
    }
}

class String
{
    public string Name { get; set; }
    public string Rank { get; set; }
}

class StringComparer : IComparer<String>
{
    public enum CompareField
    {
        Name,
        Rank
    }

    public CompareField SortBy = CompareField.Name;

    public int Compare(String x, String y)
    {
        switch (SortBy)
        {
            case CompareField.Name:
                return x.Name.CompareTo(y.Name);
            case CompareField.Rank:
                return x.Name.CompareTo(y.Rank);
        }
        return x.Name.CompareTo(y.Name);
    }
}

Answer 1

你在做

x.Name.CompareTo(y.Rank)

（名次比较）

而不是

x.Rank.CompareTo(y.Rank)

（比较排名）
