Windows 環境中支援了多種 Cultures/Regions 設定，在 .NET Framework 中要如何取出或辨識呢？基本上，只需要使用 CultureInfo 類別就可以了。

不過若要條列這些 Cultures，你必須先指定使用何種 CultureType (括號中的數字是在我的電腦上找到的數目)：

• AllCultures (226)
• FrameworkCultures (203)
• InstalledWin32Cultures (123)
• NeutralCultures (69)
• ReplacementCultures (0)
• SpecificCultures (157 - 這個數字和 NeutralCultures 的數字加起來等於 AllCultures 的數字)
• UserCustomCulture (0)
• WindowsOnlyCultures (23) - 在這個類別中的 Cultures 中，所有的 DisplayName 都已翻譯成中文

要把指定的 Cultures 條列出來，請使用以下的程式：

.aspx

    <form id="form1" runat="server">
    <div>
        <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" Font-Names="Arial"
            Font-Size="10px">
            <asp:ListItem Value="-1">Choose one ...</asp:ListItem>
            <asp:ListItem Value="0">All Cultures</asp:ListItem>
            <asp:ListItem Value="1">Framework Cultures</asp:ListItem>
            <asp:ListItem Value="2">Installed Win32 Cultures</asp:ListItem>
            <asp:ListItem Value="3">Neutral Cultures</asp:ListItem>
            <asp:ListItem Value="4">Replacement Cultures</asp:ListItem>
            <asp:ListItem Value="5">Specific Cultures</asp:ListItem>
            <asp:ListItem Value="6">User Custom Cultures</asp:ListItem>
            <asp:ListItem Value="7">Windows Only Cultures</asp:ListItem>
        </asp:DropDownList><br />
        <asp:Label ID="Label1" runat="server" Font-Names="Arial" Font-Size="10px"></asp:Label><br />
        <asp:GridView ID="GridView1" runat="server" AllowSorting="True" BackColor="White"
            BorderColor="#E7E7FF" BorderStyle='None' BorderWidth='1px' CellPadding='3' Font-Names='Verdana'
            Font-Size="10px" GridLines="Horizontal" PageSize="15">
            <FooterStyle BackColor="#B5C7DE" ForeColor="#4A3C8C" />
            <RowStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" />
            <SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="#F7F7F7" />
            <PagerStyle BackColor="#E7E7FF" ForeColor="#4A3C8C" HorizontalAlign="Right" />
            <HeaderStyle BackColor="#4A3C8C" Font-Bold="True" ForeColor="#F7F7F7" />
            <AlternatingRowStyle BackColor="#F7F7F7" />
        </asp:GridView>
        &nbsp;</div>
    </form>

使用這個程式，可以把 Windows 中可使用的各個 Culture/Region 的詳細資料列出來，包括 LCID、Name、DisplayName、NativeNmae... 等等，當你要做 Globalization 時可以做為參考。我已經順便將排序做好了，看的時候比較方便。
