c# - Startup.cs 中的 public void 方法未在构建时运行

Question

这是我的 Startup.cs 文件中的代码，我的三个方法中的两个正在构建上运行。但是，我添加了底部方法 public void PackageRequestDataAccess ，但由于某种原因它没有运行。

namespace Company.Shipping.Service
{
    public class Startup
    {
        private IHostingEnvironment _environment;
        private IConfigurationRoot _configurationRoot;

        public Startup(IHostingEnvironment env)
        {
            _environment = env;
        }

        public void ConfigureServices(IServiceCollection services)
        {
            //Code Ran successfully here 
        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IApplicationLifetime appLifetime)
        {
           //Code running successfully here
        }

        //Method below not running 
        public void PackageRequestDataAccess(Common.ServiceHost.WebHost.ServiceConfiguration configuration, IServiceCollection services)
        {
            IMongoCollection<PackageDataEntity> _reqrespcollection;
            MongoDBRepository<PackageDataEntity> _repo = new MongoDBRepository<PackageDataEntity>(configuration.ConnectionStrings["MongoDB"]);

            _reqrespcollection = _repo.Collection;

            int _expiry = Convert.ToInt32(configuration.Settings["ShippingReqRespDataTTL"]);
            TimeSpan _ttl = new TimeSpan(0, 0, _expiry);
            CreateIndexOptions index = new CreateIndexOptions();
            index.ExpireAfter = _ttl;

            var _key = Builders<PackageDataEntity>.IndexKeys.Ascending("RequestSentOn");
            _reqrespcollection.Indexes.CreateOneAsync(_key);
        }
    }
}

每当应用程序启动时，我都需要运行所有这三个方法。

根据 MSDN 文档 available here启动期间仅调用Configure 和ConfigureServices。

The Startup class must include a Configure method and can optionally include a ConfigureServices method, both of which are called when the application starts.

在您的情况下，您可能可以将逻辑添加到此方法的任何一个中，或者仅从上述方法中调用该方法。
