【问题描述】：

在我的项目中，我有两种支持的语言（德语 - “de”和英语 - “en”） 我有如下资源文件：Home.aspx.de.resx, Home.aspx.en.resx, Home.aspx.resx

是否可以动态读取当前 webproject 中支持的语言？ 如果它们只是“de”和“en”，我不想手动验证它，就像我在下面的代码中所做的那样：

if (langName != "en" || langName != "de")
                    
                        ci = new CultureInfo("en");

                        this.Session["Culture"] = ci;
                    

我想访问 webproject 语言，例如：CultureInfo.(Who knows)..。 如果我要添加一种新语言，f.E. “fr”我需要再次手动将其添加到我的逻辑中。

我的Application_AcquireRequestState 方法如下所示：

protected void Application_AcquireRequestState(object sender, EventArgs e)
        
            if (HttpContext.Current.Session != null)
            
                //Create culture info object 
                CultureInfo ci = (CultureInfo)this.Session["Culture"];

                //Checking first if there is no value in session 
                //and set default language 
                //this can happen for first user's request
                if (ci == null)
                
                    //Sets default culture to english invariant
                    string langName = "en";

                    //Try to get values from Accept lang HTTP header
                    if (HttpContext.Current.Request.UserLanguages != null && HttpContext.Current.Request.UserLanguages.Length != 0)
                    
                        //Gets accepted list 
                        langName = HttpContext.Current.Request.UserLanguages[0].Substring(0, 2);

                    
                    if (langName != "en" || langName != "de")
                    
                        ci = new CultureInfo("en");

                        this.Session["Culture"] = ci;
                    
                    else
                    
                        ci = new CultureInfo(langName);
                        this.Session["Culture"] = ci;
                    
                

                //Finally setting culture for each request
                Thread.CurrentThread.CurrentUICulture = ci;
                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(ci.Name);

            
        

【参考方案1】：

您能否尝试加载指定语言的文化，如果不存在则加载默认语言？我已经在我的一个网络应用程序中做到了这一点。您可以在基本页面中使用类似的内容。

        /// <summary>
    /// Initializes culture for the page
    /// </summary>
    [VersionChange( "6.1.34.89", "24/12/2009", "Custom Cultures added" )]
    protected override void InitializeCulture()
    
        try
        
            CultureInfo oCultureInfo;

            try
            
                oCultureInfo = CultureInfo.CreateSpecificCulture( this.CurrentCustomCulture );
            
            catch ( ArgumentException )
            
                //Get culture info based on Great Britain
                CultureInfo cultureInfo = new CultureInfo( "en-GB" );
                RegionInfo regionInfo = new RegionInfo( cultureInfo.Name );

                CultureAndRegionInfoBuilder cultureAndRegionInfoBuilder = new CultureAndRegionInfoBuilder( this.CurrentCustomCulture, CultureAndRegionModifiers.None );

                cultureAndRegionInfoBuilder.LoadDataFromCultureInfo( cultureInfo );
                cultureAndRegionInfoBuilder.LoadDataFromRegionInfo( regionInfo );

                // Custom Changes
                cultureAndRegionInfoBuilder.CultureEnglishName = this.CurrentCustomCulture;
                cultureAndRegionInfoBuilder.CultureNativeName = this.CurrentCustomCulture;

                cultureAndRegionInfoBuilder.Register();

                oCultureInfo = CultureInfo.GetCultureInfo( this.CurrentCustomCulture );
            
            catch ( Exception )
            
                throw;
            

            Thread.CurrentThread.CurrentCulture = oCultureInfo;
            Thread.CurrentThread.CurrentUICulture = oCultureInfo;

            Page.Culture = oCultureInfo.Name;
            Page.UICulture = oCultureInfo.Name;

            base.InitializeCulture();
        
        catch ( Exception )
        
            throw;
        
    

如果你想从服务器读取可用的文化，你可以使用

using System.Globalization;

CultureInfo.GetCultures( CultureTypes.AllCultures );

and CultureInfo.GetCultures( CultureTypes.UserCustomCulture );

【讨论】：

这正是我不想做的。如果要添加西班牙语或法语，则需要手动在代码中添加新语言。我想阅读资源文件中的语言。然后如果不存在则加载默认语言。

代码首先尝试将文化设置为此。CurrentCustomCulture 是每个用户变量，您不需要添加任何代码，只需为新语言添加新资源文件
