我想我的startup.cs有问题，因为我没有从我的<IOption> config中获得任何值
所以..我们有我们的appsettings.json

"Config": {
    "ApplicationName": "some name",
    "ConnectionString": "someconstring",
    "Version": "1.0.0"
  },

字符串
这是我们的模型

public class Config
    {   
        public string ApplicationName { get; set; }
        public string ConnectionString { get; set; }
        public string Version { get; set; }
    }

型

startup.cs

public Startup(IConfiguration configuration)

    {
        Configuration = configuration;
    }


public static IConfiguration Configuration { get; set; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
        // Add functionality to inject IOptions<T>
        services.AddOptions();

        // Add our Config object so it can be injected
        services.Configure<Config>(Configuration);
    }

然后在我们的控制器中，我尝试加载这些数据，但不幸的是，它们仍然是空的。

private IOptions<Config> config;
            public CompaniesController(IOptions<Config> config)
            {
                this.config = config;
            }

型
我试着用类似的东西更改startup.cs

services.Configure<Config>(options =>
            {
                options.ConnectionString = Configuration.GetSection("Config:ConnectionString").Value;
            });

但这似乎行不通

但显然我忽略了一个关键点

Program.cs

public class Program
    {
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .Build();
    }

整个Appsettings.json文件

{
  "Config": {
    "ApplicationName": "somename",
    "ConnectionString": "someconstring",
    "Version": "1.0.0"
  },
  "Logging": {
    "IncludeScopes": false,
    "Debug": {

        "Default": "Warning"
