从Blazor基类中的应用程序设置中获取值

// 在Program.cs中的CreateHostBuilder方法中配置应用程序设置
public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureAppConfiguration((hostingContext, config) =>
        {
            config.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
            config.AddEnvironmentVariables();
        })
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });

// 在Blazor基类中注入IConfiguration接口
public class MyBaseComponent : ComponentBase
{
    [Inject]
    protected IConfiguration Configuration { get; set; }

    protected override void OnInitialized()
    {
        base.OnInitialized();

        // 通过IConfiguration接口获取应用程序设置中的值
        var someValue = Configuration.GetValue<string>("SomeSetting");
        Console.WriteLine(someValue);
    }
}
