在ASP.NET Core中将类型的实例注册到ServiceCollection

Question

我正在使用Asp.Net Core 2.2，我想将一个类型的实例注册为基本类型。

在启动文件中，我尝试按如下所示注册类型和实例：

foreach (var type in typesFromAssemblies)
        {
            var settings = Activator.CreateInstance(type);

            foreach (var prop in type.GetProperties())
            {
                if (!prop.CanRead || !prop.CanWrite)
                {
                    continue;
                }

                var key = type.Name + "." + prop.Name;

                // load instance from database
                var setting = GetSettingByKey<string>(provider, key, loadSharedValueIfNotFound: true);

                if (setting == null)
                {
                    continue;
                }

                object value = CommonHelper.GetMovCustomTypeConverter(prop.PropertyType)
                    .ConvertFromInvariantString(setting);

                // set property
                prop.SetValue(settings, value, null);
            }

            // how I can set "settings" in services?
            // services.Add(new ServiceDescriptor(settings.GetType(), settings, lifetime));
        }

如何为服务设置“设置”实例？
