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 = supportedCultures
   7 });
