调用ServiceCollection的BuildServiceProvider()创建的ServiceProvider，可以用来获取BuildServiceProvider()之前ServiceCollection...ServiceCollection(); services.AddTransient(); using (ServiceProvider sp = services.BuildServiceProvider...ServiceCollection(); services.AddTransient(); using (ServiceProvider sp = services.BuildServiceProvider...ServiceCollection(); services.AddSingleton(); using (ServiceProvider sp = services.BuildServiceProvider...ServiceCollection(); services.AddScoped(); using (ServiceProvider sp = services.BuildServiceProvider

内部真正使用的是一个实现了IServiceProvider接口的内部类型（该类型的名称为“ServiceProvider”），我们不能直接创建该对象，只能间接地通过调用IServiceCollection接口的扩展方法BuildServiceProvider...1: public static class ServiceCollectionExtensions 2: { 3: public static IServiceProvider BuildServiceProvider...IGux>(): {0}", serviceProvider.GetService()); 16: } 17: } 接下来我们调用ServiceCollection对象的扩展方法BuildServiceProvider...23: public class Foo : IFoobar {} 24: public class Bar : IFoobar {} 在调用ServiceCollection对象的扩展方法BuildServiceProvider...string[] args) 4: { 5: IServiceProvider serviceProvider = new ServiceCollection().BuildServiceProvider
