IComparer没有排序简单的abc？

我有我的String类设置,并创建了一个StringComparer实现IComparer并希望对我的字符串数组进行排序Rank并显示它的类.目前它显示:

一个,X,C

当我有点上Rank.为什么会这样？它应该显示:

A,C,X

或者一夜之间改变了字母？

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
{
    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);
    }
}

你在做

x.Name.CompareTo(y.Rank)

(比较姓名和职级)

代替

x.Rank.CompareTo(y.Rank)

(比较排名和排名)

你在做

x.Name.CompareTo(y.Rank)

(比较姓名和职级)

代替

x.Rank.CompareTo(y.Rank)

(比较排名和排名)
