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

Question

In my Razor view I let user click the few buttons with the letters on it.

<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">

Effect is neat:

but the problem is that in Poland we also have letters like: Ś(after S), Ć(after C), Ą(after A), Ę(after E), Ó(after O).

I don't want to insert them into the website implicitly by typing them.

Is there a method providing alphabet as collection for certain localization?

ps. It's worth noting that an alphabet doesn't contain all of a language's characters. For example:

• uppercase and lowercase characters are different; yet the alphabet only uses one or the other.
• some accented characters may be used despite not being in the official alphabet; eg Café.
• numbers
• punctuation
