在(zai)startup里(li)，也是可以直(zhi)接使(shi)用配置文件里(li)信息(xi)的，一般可以這樣使(shi)用

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

    public IConfiguration Configuration { get; }
    public void ConfigureServices(IServiceCollection services)
    {
        var oidcOptions = new OpenIdConnectOptions();
        this.Configuration.GetSection("Oidc").Bind(oidcOptions);
        services.AddSingleton(oidcOptions);
     
 
      var ClientId = Configuration["Oidc:ClientId"];
    }
}

上面(mian)的代碼將從(cong)配置文(wen)件"Oidc"中獲取"ClientId"這個(ge)屬(shu)性的內容(rong)。
