ServiceCollectionDescriptorExtensions.TryAddSingleton Metodo

Aggiunge l'oggetto service specificato come servizio Singleton a collection se il tipo di servizio non è già stato registrato.Adds the specified service as a Singleton service to the collection if the service type hasn't already been registered.

[System::Runtime::CompilerServices::Extension]
 static void TryAddSingleton(Microsoft::Extensions::DependencyInjection::IServiceCollection ^ collection, Type ^ service);

public static void TryAddSingleton (this Microsoft.Extensions.DependencyInjection.IServiceCollection collection, Type service);

<Extension()>
Public Sub TryAddSingleton (collection As IServiceCollection, service As Type)

Parametri

Aggiunge l'oggetto service specificato come servizio Singleton usando la factory specificata in implementationFactory a collection se il tipo di servizio non è già stato registrato.Adds the specified service as a Singleton service using the factory specified in implementationFactory to the collection if the service type hasn't already been registered.
