我正在尝试访问我的 Asp.net core v6 应用程序 Program.cs 文件中的 appsettings.json，但在此版本的 .Net 中，Startup 类和 Program 类合并在一起，并且 using 和 another 语句被简化并从 Program 中删除。CS。在这种情况下，如何访问 IConfiguration 或如何使用依赖注入？

代码

这是 Asp.net 6 为我创建的默认 Program.cs

var builder = WebApplication.CreateBuilder(args);
// Add services to the container.
builder.Services.AddControllers();
builder.Services.AddStackExchangeRedisCache(options =>
{
    options.Configuration = "localhost:6379";
});

builder.Services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new() { Title = "BasketAPI", Version = "v1" });
});
var app = builder.Build();
// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "BasketAPI v1"));
}
app.UseHttpsRedirection(); …

在.NET Core Console应用程序上,我正在尝试将自定义appsettings.json文件中的设置映射到自定义配置类.

我在线查看了几个资源,但无法使.Bind扩展方法有效(我认为它适用于asp.net应用程序或以前版本的.Net Core,因为大多数示例都表明了这一点).

这是代码:

 static void Main(string[] args)
    {

        var builder = new ConfigurationBuilder()
        .SetBasePath(Directory.GetCurrentDirectory())
        .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);

        IConfigurationRoot configuration = builder.Build();

        //this is a custom configuration object
        Configuration settings = new Configuration();

        //Bind the result of GetSection to the Configuration object
        //unable to use .Bind extension
        configuration.GetSection("MySection");//.Bind(settings);

        //I can map each item from MySection manually like this
        settings.APIBaseUrl = configuration.GetSection("MySection")["APIBaseUrl"];

        //what I wish to accomplish is to map the section to my Configuration object
        //But …

我正在使用 .NET Core 3.1 创建一个控制台应用程序，我想要一个 appsettings json 在执行开始时加载所有环境、路径、变量...，然后从其他库类中获取值。我已经使用 appsettings json 中包含的数据创建了一个“设置”类。这是我在教程中已经看到的，但我无法获得任何价值。

//Start.cs
public class Startup
{
        public Startup(IHostingEnvironment env)
        {
            var builder = new ConfigurationBuilder()
                .SetBasePath(env.ContentRootPath)
                .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
                .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
                .AddEnvironmentVariables();

            Configuration = builder.Build();
        }

        public IConfiguration Configuration { get; }

        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }
}

//Settings.cs
 public class Settings
    {
        public ConnectionStrings ConnectionStrings { get; set; }
        public Logging Logging { get; set; }
        public AppSettings AppSettings { get; set; } …
