如何在char数组或列表或集合或任何IEnumerable中获取本地化字母？

Question

在我的Razor视图中，我让用户点击带有字母的几个按钮。

<table class="table">
    <tr>
        @{for (int i = 0; i < 26; i++) {
            char letter = (char)('A' + i);
            @Html.ActionLink(letter + "", "Index", new { firstLetterOfLastName = letter }, new { @class = "btn btn-default" })
        }}
    </tr>
</table>
<table class="table">

效果很好：

但问题是在波兰我们也有这样的字母：Ś（在S之后），Ć（在C之后），Ą（在A之后），Ę（在E之后），Ó（在O之后）。

我不想通过输入隐式地将它们插入网站。

是否有提供字母作为特定本地化集合的方法？
