你的比较器看起来不对。你仍然只是在默认的文本顺序中排序。当然你想解析这两个数字并基于此排序：

public int Compare(Object stringA, Object stringB)
{
    string[] valueA = stringA.ToString().Split('/');
    string[] valueB = stringB.ToString().Split('/');

    if (valueA.Length != 2 || valueB.Length != 2)
    {
        stringA.ToString().CompareTo(stringB.ToString());
    }

    // Note: do error checking and consider i18n issues too :)
    if (valueA[0] == valueB[0]) 
    {
        return int.Parse(valueA[1]).CompareTo(int.Parse(valueB[1]));
    }
    else
    {
        return int.Parse(valueA[0]).CompareTo(int.Parse(valueB[0]));
    }
}

字符串
(Note这与您的问题不符，您的问题说明您已经调试并验证了Compare返回的值是正确的-但我担心我怀疑在这方面存在人为错误。）
此外，Sven是对的--改变items的值根本不会改变绑定列表。你应该添加：

this.Items = items;

我遇到了一般自然排序的问题，并在这里发表了解决方案：
Natural Sort Compare with Linq OrderBy()

public class NaturalSortComparer<T> : IComparer<string>, IDisposable
{
    private bool isAscending;

    public NaturalSortComparer(bool inAscendingOrder = true)
    {
        this.isAscending = inAscendingOrder;
    }

    #region IComparer<string> Members

    public int Compare(string x, string y)
    {
        throw new NotImplementedException();
    }

    #endregion

    #region IComparer<string> Members

    int IComparer<string>.Compare(string x, string y)
    {
        if (x == y)
            return 0;

        string[] x1, y1;

        if (!table.TryGetValue(x, out x1))
        {
            x1 = Regex.Split(x.Replace(" ", ""), "([0-9]+)");
            table.Add(x, x1);
        }

        if (!table.TryGetValue(y, out y1))
        {
            y1 = Regex.Split(y.Replace(" ", ""), "([0-9]+)");
            table.Add(y, y1);
        }

        int returnVal;

        for (int i = 0; i < x1.Length && i < y1.Length; i++)
        {
            if (x1[i] != y1[i])
            {
                returnVal = PartCompare(x1[i], y1[i]);
                return isAscending ? returnVal : -returnVal;
            }
        }

        if (y1.Length > x1.Length)
        {
            returnVal = 1;
        }
        else if (x1.Length > y1.Length)
        { 
            returnVal = -1; 
        }
        else
        {
            returnVal = 0;
        }

        return isAscending ? returnVal : -returnVal;
    }

    private static int PartCompare(string left, string right)
    {
        int x, y;
        if (!int.TryParse(left, out x))
            return left.CompareTo(right);

        if (!int.TryParse(right, out y))
            return left.CompareTo(right);

        return x.CompareTo(y);
    }

    #endregion

    private Dictionary<string, string[]> table = new Dictionary<string, string[]>();

    public void Dispose()
    {
        table.Clear();
        table = null;
    }
}

我们能不能这样做：

public class MyComparer : IComparer<string>
{

    public int Compare(string stringA, string stringB)
    {
        string small = stringA;
        string big = stringB;
        if (stringA.Length > stringB.Length)
        {
            small = stringB;
            big = stringA;
        }
        else if (stringA.Length < stringB.Length)
        {
            small = stringA;
            big = stringB;
        }
        for (int j = 0; j < small.Length; j++)
        {
            if (Convert.ToInt32(small[j]) > Convert.ToInt32(big[j])) return -1;
            if (Convert.ToInt32(small[j]) < Convert.ToInt32(big[j])) return 1;
        }

        //big is indeed bigger
        if (big.Length > small.Length) return 1;

        //finally they are smae
        return 0;
    }
}

字符串
使用方法：

string[] inputStrings = {"_abc*&","#almnp","abc" };
//string[] inputStrings = { "#", "_", "_a", "@", "_" };
MyComparer computer = new MyComparer();
var kola = inputStrings.OrderBy(x => x, new MyComparer()).ToArray();

型
这是相同的：

Array.Sort(inputStrings, StringComparer.Ordinal);

型

你可以使用Alphanum算法：

(...)
    items.OrderBy(x => property.GetValue(x), new AlphanumComparator())
  (...)

排序列表只绑定到局部变量items，而不是绑定列表的Items属性，因此它保持未排序。
[编辑]基本上，你只是简单地扔掉你的排序努力的结果;-）

有一个Windows API：

public sealed class NaturalStringComparer : IComparer<string>
{
  readonly ListSortDirection _direction;

  public NaturalStringComparer(
    ListSortDirection direction = ListSortDirection.Ascending)
  {
    _direction = direction;
  }

  public int Compare(string x, string y)
  {
    return _direction == ListSortDirection.Ascending 
      ? NaturalStringComparer.SafeNativeMethods.StrCmpLogicalW(x, y) 
      : NaturalStringComparer.SafeNativeMethods.StrCmpLogicalW(y, x);
  }

  [SuppressUnmanagedCodeSecurity]
  static class SafeNativeMethods
  {
    [DllImport("shlwapi.dll", CharSet = CharSet.Unicode)]
    public static extern int StrCmpLogicalW(string psz1, string psz2);
  }
}
