本地化ASP.NET核心模型绑定错误消息

若要本地化ASP.NET Core模型绑定错误消息，请按照下列步骤操作：

1. 创建资源文件 - 在解决方案的Resources文件夹下创建资源文件，并将文件命名为ModelBindingMessages.resx。名称可以是其他任何名称，但我们将使用它来创建本地化程序。
   

2. 添加资源键 - 打开资源文件并添加要用于本地化错误消息的键和值。我使用了键和值

3. 配置选项 - 在ConfigureServices方法中，添加时Mvc，配置其选项以设置以下内容的消息访问者ModelBindingMessageProvider

4.  1 ???services.AddMvc(options => 2 ????????????{ 3 ????????????????IStringLocalizerFactory F = services.BuildServiceProvider(). 4 ????????????????GetService<IStringLocalizerFactory>(); 5 ????????????????IStringLocalizer L = F.Create("ModelBindingMessages", 6 ????????????????????"AspNetCoreLocalizationSample"); 7 ????????????????options.ModelBindingMessageProvider. 8 ????????????????SetValueIsInvalidAccessor((x) => L["The value ‘{0}‘ is invalid."]); 9 ????????????????options.ModelBindingMessageProvider.SetValueMustBeANumberAccessor(10 ????????????????????(x) =>L["The field {0} must be a number."]);11 ????????????????options.ModelBindingMessageProvider.SetMissingBindRequiredValueAccessor(12 ????????????????????(x) => L["A value for the ‘{0}‘ property was not provided.", x]);13 ????????????????options.ModelBindingMessageProvider.SetAttemptedValueIsInvalidAccessor(14 ????????????????????(x, y) => L["The value ‘{0}‘ is not valid for {1}.", x, y]);15 ????????????????options.ModelBindingMessageProvider.SetMissingKeyOrValueAccessor(16 ????????????????????() => L["A value is required."]);17 ????????????????options.ModelBindingMessageProvider.SetUnknownValueIsInvalidAccessor(18 ????????????????????(x) => L["The supplied value is invalid for {0}.", x]);19 ????????????????options.ModelBindingMessageProvider.SetValueMustNotBeNullAccessor(20 ????????????????????(x) => L["Null value is invalid.", x]);21 ????????????}).AddDataAnnotationsLocalization()22 ????.AddViewLocalization();23 ????services.Configure<RequestLocalizationOptions>(options =>24 ????{25 ????????var supportedCultures = new[]{new CultureInfo("en"), new CultureInfo("zh-cn")};26 ????????options.DefaultRequestCulture = new RequestCulture("en", "en");27 ????????options.SupportedCultures = supportedCultures;28 ????????options.SupportedUICultures = supportedCultures;29 ????});

5. 还要在Configure方法开头添加此代码：

   1 var supportedCultures = new[] { new CultureInfo("en"), new CultureInfo("zh-CN") };2 app.UseRequestLocalization(new RequestLocalizationOptions()3 {4 ????DefaultRequestCulture = new RequestCulture(new CultureInfo("en")),5 ????SupportedCultures = supportedCultures,6 ????SupportedUICultures = supportedCultures7 });
