.NET i18n 多语言支持与国际化

环境 WIN10 VS2022 .NET8  

1.👋创建项目

2.👀创建Resources Controllers

HomeController.en.resx

HomeController.fr.resx

HomeController.zh.resx

3.🌱Program.cs添加国际化支持

// 添加国际化支持
builder.Services.AddLocalization(options =>
{
    options.ResourcesPath = "Resources";
});

var app = builder.Build();

// 多语言
var supportedCultures = new List<CultureInfo>
            {
                new CultureInfo("en"),
                new CultureInfo("zh"),
                 new CultureInfo("fr"),
            };

app.UseRequestLocalization(new RequestLocalizationOptions
{
    DefaultRequestCulture = new RequestCulture("zh"),
    SupportedCultures = supportedCultures,
    SupportedUICultures = supportedCultures
});

4.⚡注入localizer

        private readonly IStringLocalizer<HomeController> localizer;

      public HomeController(ILogger<HomeController> logger,     
      IStringLocalizer<HomeController> localizer)
      {
          _logger = logger;
          this.localizer = localizer;
      }

5.📫编写调用方法

        [HttpGet]
        public ActionResult<string> Get()
        {
            string rsstr= localizer.GetString("String1").Value;//?ui-culture=zh
            return rsstr;
        }

默认是中文

?ui-culture=en 则取对应HomeController.en.resx 里面的String1
