Question

我开发了一个Web应用程序，它是一个动态站点。我可以为我的网站添加多语言选项吗？

如果是，是否有任何插件？如何进一步开发多语言应用程序？

Answer 1

我们有DropdownList控件。在其SelectedIndexChanged事件中，它回发，然后我们更改网站文化，然后加载相应的资源文件......

DropDownList ASP.NET代码

<asp:DropDownList ID="ddlLanguage" runat="server" CssClass="select-language" AutoPostBack="true">
    <asp:ListItem Value="en-US" Text="English" title="/images/Flag_USA.gif"></asp:ListItem>
    <asp:ListItem Value="it-IT" Text="Italiano" title="/images/Flag_Italian.gif"></asp:ListItem>
    <asp:ListItem Value="fr-FR" Text="Française" title="/images/Flag_French.gif"></asp:ListItem>
</asp:DropDownList>

所有网页继承的公共类

using System;
using System.Web;
using System.Threading;
using System.Globalization;

public class languagebase : System.Web.UI.Page
{
    protected override void InitializeCulture()
    {
        try
        {
            string LanguageCode = Request["ctl00$ucMenu$ddlLanguage"]; // Language Drop Down Control in Front End
            if (!LanguageCode.IsNullOrEmpty())
            {
                setCulture(LanguageCode);  // Set Culture language from drop down
                Request.Cookies["LanguageCode"].Value = LanguageCode; // Update REQUEST Cookie language from drop down
                SetCookies(LanguageCode); // Set Cookie language from drop down
            }
        }
        catch(Exception ex)
        {
            setCulture("en-US"); // Set default language
            Request.Cookies["LanguageCode"].Value = "en-US"; // Update REQUEST Cookie language to default
            SetCookies("en-US"); // Set default language
        }
        base.InitializeCulture();
    }

    private static void setCulture(string LanguageValue)
    {
       Thread.CurrentThread.CurrentUICulture = new CultureInfo(LanguageValue);
       Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(LanguageValue);
    }

    public void SetCookies(string strLanguage)
    {
        System.Web.HttpContext.Current.Response.Cookies["LanguageCode"].Value = strLanguage;
        System.Web.HttpContext.Current.Response.Cookies["LanguageCode"].Expires = DateTime.Now.AddDays(15);
    }
}

扩展方法（仅供参考）

public static Boolean IsNullOrEmpty(this String original)
{
    return string.IsNullOrEmpty(original);
}

请在开始实施前查看以下链接：

这些会使您使用的所有网页都继承自languagebase类，如下所示：

using System;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class Default : languagebase
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
}

多语言应用程序，Microsoft Visual Studio？
