c# – 添加法语字符时抛出异常的SortedList

我在排序列表中添加了一些独特的法语单词,但它似乎没有区分某些单词,如“bœuf”&伯夫”.

private static void TestSortedList()
{

    Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("fr-fr");
    SortedList sortedList = new SortedList(new Comparer(CultureInfo.CurrentCulture));

    try
    {
        sortedList.Add("bœuf", "Value1");
        sortedList.Add("boeuf", "Value1");
    }
    catch(Exception ex)
    {
        Console.WriteLine(ex.ToString());
    }
}

因此,上面的代码抛出异常“System.ArgumentException：Item已被添加.”
请帮忙！

解决方法:

    SortedList sortedList = new SortedList(StringComparer.Ordinal);

    try
    {
        sortedList.Add("bœuf", "Value1");
        sortedList.Add("boeuf", "Value1");
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());
    }

作品.为了解释,Ordinal和OrdinalIgnoreCase比较器比较字符字节,它们对于不同的字符是不同的.
也见Difference between InvariantCulture and Ordinal string comparison.
