在C#中获取服务生命周期信息

using System;
using System.Linq;
using Microsoft.Extensions.DependencyInjection;

class Program
{
    static void Main(string[] args)
    {
        var services = new ServiceCollection();
        // 注册服务...
        services.AddSingleton<ISingletonService, SingletonServiceImpl>();
        servicesScoped<IScopedService, ScopedServiceImpl>();
        services.AddTransient<ITransientService, TransientServiceImpl>();

        var serviceProvider = services.BuildServiceProvider();

        // 使用反射获取服务生命周期信息
        var descriptor = serviceProvider.GetService<ServiceDescriptor>();
        foreach (var service in descriptor)
        {
            Console.WriteLine($"Service Type: {service.ServiceType}, Lifetime: {service.Lifetime}");
        }
    }
}

interface ISingletonService : IService { }
class SingletonServiceImpl : ISingletonService { }
interface IScopedService : IService { }
class ScopedServiceImpl : IScopedService { }
interface ITransientService : IService { }
class TransientServiceImpl : ITransientService { }
