使用大括号而不定义函数,结构等

Question

在分析Orchard.cms源代码时,我发现了有趣的代码,当C#中的括号不用于定义任何内部对象时.似乎它是为某些上下文使用而制作的.你能澄清一下使用像这样的括号的目标吗？

这是它的代码示例:

 builder.RegisterType<DefaultOrchardHost>().As<IOrchardHost>().As<IEventHandler>().SingleInstance();
 {
     builder.RegisterType<ShellSettingsManager>().As<IShellSettingsManager>().SingleInstance();

     builder.RegisterType<ShellContextFactory>().As<IShellContextFactory>().SingleInstance();
     {
         builder.RegisterType<ShellDescriptorCache>().As<IShellDescriptorCache>().SingleInstance();

         builder.RegisterType<CompositionStrategy>().As<ICompositionStrategy>().SingleInstance();
         {
             builder.RegisterType<ShellContainerRegistrations>().As<IShellContainerRegistrations>().SingleInstance();
             builder.RegisterType<ExtensionLoaderCoordinator>().As<IExtensionLoaderCoordinator>().SingleInstance();
             builder.RegisterType<ExtensionMonitoringCoordinator>().As<IExtensionMonitoringCoordinator>().SingleInstance();
             builder.RegisterType<ExtensionManager>().As<IExtensionManager>().SingleInstance();
             {
                 builder.RegisterType<ExtensionHarvester>().As<IExtensionHarvester>().SingleInstance();
                 builder.RegisterType<ModuleFolders>().As<IExtensionFolders>().SingleInstance()
                     .WithParameter(new NamedParameter("paths", new[] { "~/Modules" }));
                 builder.RegisterType<CoreModuleFolders>().As<IExtensionFolders>().SingleInstance()
                     .WithParameter(new NamedParameter("paths", new[] { "~/Core" }));
                 builder.RegisterType<ThemeFolders>().As<IExtensionFolders>().SingleInstance()
                     .WithParameter(new NamedParameter("paths", new[] { "~/Themes" }));

                 builder.RegisterType<CoreExtensionLoader>().As<IExtensionLoader>().SingleInstance();
                 builder.RegisterType<ReferencedExtensionLoader>().As<IExtensionLoader>().SingleInstance();
                 builder.RegisterType<PrecompiledExtensionLoader>().As<IExtensionLoader>().SingleInstance();
                 builder.RegisterType<DynamicExtensionLoader>().As<IExtensionLoader>().SingleInstance();
                 builder.RegisterType<RawThemeExtensionLoader>().As<IExtensionLoader>().SingleInstance();
             }
         }

         builder.RegisterType<ShellContainerFactory>().As<IShellContainerFactory>().SingleInstance();
     }

     builder.RegisterType<DefaultProcessingEngine>().As<IProcessingEngine>().SingleInstance();
 }

在这种情况下,目标只是让开发人员/人类更容易理解在阅读代码时类型如何相关联,以便更容易理解代码.

(使用这样的花括号将缩进大多数IDE中的行,例如Visual Studio)
