System.Globalization.CultureInfo不包含名称的定义

错误489'System.Globalization.CultureInfo'不包含'EnglishName'的定义，并且找不到扩展方法'EnglishName'接受类型为'System.Globalization.CultureInfo'的第一个参数(您是否缺少使用指令还是程序集引用?)错误488在未引用的程序集中定义了类型'System.Globalization.CultureInfo'.您必须添加对程序集'System.Globalization，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'的引用.这是我尝试过的几行代码: var y = new CultureInfo("en");//作品var z = y.Name;//作品var x = model.languages.First().AssociatedCulture.EnglishName;//此行的错误. 我不了解这个幻影错误.如果有帮助，则创建Language.cs的项目将使用.NET Portable v.4.5.我尝试将其添加到web.config程序集块中，但没有骰子. <编译defaultLanguage ="c#" debug ="true" targetFramework ="4.5"><装配体>< add assembly ="System.Globalization，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a"/>< add assembly ="System.Runtime，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a"/>< add assembly ="System.Web.Abstractions，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/>< add assembly ="System.Web.Routing，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/>< add assembly ="System.Data.Linq，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = B77A5C561934E089"/>< add assembly ="System.Web.Helpers，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/>< add assembly ="System.Web.Mvc，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/>< add assembly ="System.Web.WebPages，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/>< add assembly ="System.Web.Abstractions，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35"/>< add assembly ="System.Web.Routing，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35"/>< add assembly ="System.Web.Mvc，Version = 5.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35"/></程序集>< buildProviders>< add extension =.cshtml" type ="System.Web.WebPages.Razor.RazorBuildProvider，System.Web.WebPages.Razor，Version = 3.0.0.0，Culture = neutral，PublicKeyToken = 31BF3856AD364E35"/></buildProviders></compilation> 有人曾经遇到过这个问题吗?是由.NET Portable引起的吗?解决方案您需要项目引用来 System.Globalization .在编辑 web.config 文件时，您将添加从 .aspx / .cshtml 文件，这与您的项目引用(这些引用是您的项目的输出DLL的引用)是分开的且不同的.通过解决方案资源管理器在Visual Studio中添加项目引用.I have this peculiar issue with the System.Globalization.CultureInfo class and the System.Globalization namespace. I'm returning an object (Languages) from an API call that has a CultureInfo property. I'm able to successfully pull this on the client side into an IENumerable<Language> languages {get; set;} but when I try to build with a line such as var x = model.languages.First().AssociatedCulture.Name I'm met with the following errors:Error 489 'System.Globalization.CultureInfo' does not contain a definition for 'EnglishName' and no extension method 'EnglishName' accepting a first argument of type 'System.Globalization.CultureInfo' could be found (are you missing a using directive or an assembly reference?)Error 488 The type 'System.Globalization.CultureInfo' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Globalization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.Here is the sequence of lines I have run to try this out:var y = new CultureInfo("en"); //worksvar z = y.Name; //worksvar x = model.languages.First().AssociatedCulture.EnglishName; //error at this line.I don't understand this phantom error. If it helps, the project that creates Language.cs uses the .NET portable v.4.5.I have tried adding this to the web.config assemblies block but no dice.<compilation defaultLanguage="c#" debug="true" targetFramework="4.5"> <assemblies> <add assembly="System.Globalization , Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> <add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Helpers, Version=2.0.0.0, Culture=neutral,PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Mvc, Version=4.0.0.0, Culture=neutral,PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.WebPages, Version=2.0.0.0, Culture=neutral,PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> <add assembly="System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </assemblies> <buildProviders> <add extension=".cshtml" type="System.Web.WebPages.Razor.RazorBuildProvider, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </buildProviders> </compilation>Has anyone experienced this issue before? Is it somehow caused by .NET portable? 解决方案 You need a project reference to System.Globalization.When you edit the web.config file you're adding a reference for the dynamic assembly that's generated from your .aspx/.cshtml files, this is separate and distinct from your project references (which are references for the output DLL from your project).Add a Project Reference in Visual Studio via Solution Explorer. 这篇关于System.Globalization.CultureInfo不包含名称的定义的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
