ServiceCollectionDescriptorExtensions.TryAddEnumerable 方法

定义

命名空间:

Microsoft.Extensions.DependencyInjection.Extensions

程序集:

Microsoft.Extensions.DependencyInjection.Abstractions.dll

包:

Microsoft.Extensions.DependencyInjection.Abstractions v9.0.0-preview.7.24405.7

重载

TryAddEnumerable(IServiceCollection, ServiceDescriptor)	如果现有描述符具有相同 ServiceType 和 services 中尚不存在的实现，则添加 ServiceDescriptor。
TryAddEnumerable(IServiceCollection, IEnumerable<ServiceDescriptor>)	如果现有描述符具有相同 ServiceType 和 services 中尚不存在的实现，则添加指定的 ServiceDescriptor。

TryAddEnumerable(IServiceCollection, ServiceDescriptor)

Source:

ServiceCollectionDescriptorExtensions.cs

如果现有描述符具有相同 ServiceType 和 services 中尚不存在的实现，则添加 ServiceDescriptor。

public:
[System::Runtime::CompilerServices::Extension]
 static void TryAddEnumerable(Microsoft::Extensions::DependencyInjection::IServiceCollection ^ services, Microsoft::Extensions::DependencyInjection::ServiceDescriptor ^ descriptor);

public static void TryAddEnumerable (this Microsoft.Extensions.DependencyInjection.IServiceCollection services, Microsoft.Extensions.DependencyInjection.ServiceDescriptor descriptor);

static member TryAddEnumerable : Microsoft.Extensions.DependencyInjection.IServiceCollection * Microsoft.Extensions.DependencyInjection.ServiceDescriptor -> unit

<Extension()>
Public Sub TryAddEnumerable (services As IServiceCollection, descriptor As ServiceDescriptor)

参数

services

IServiceCollection

IServiceCollection

descriptor

ServiceDescriptor

ServiceDescriptor

注解

注册支持同一服务类型的多个注册的服务类型的服务实现时使用 TryAddEnumerable(IServiceCollection, ServiceDescriptor) 。 使用 Add(IServiceCollection, ServiceDescriptor) 不是幂等的，如果调用两次，可以添加重复 ServiceDescriptor 实例。 使用 TryAddEnumerable(IServiceCollection, ServiceDescriptor) 将阻止注册多个实现类型。

TryAddEnumerable(IServiceCollection, IEnumerable<ServiceDescriptor>)

Source:

ServiceCollectionDescriptorExtensions.cs

如果现有描述符具有相同 ServiceType 和 services 中尚不存在的实现，则添加指定的 ServiceDescriptor。

public:
[System::Runtime::CompilerServices::Extension]
 static void TryAddEnumerable(Microsoft::Extensions::DependencyInjection::IServiceCollection ^ services, System::Collections::Generic::IEnumerable<Microsoft::Extensions::DependencyInjection::ServiceDescriptor ^> ^ descriptors);

public static void TryAddEnumerable (this Microsoft.Extensions.DependencyInjection.IServiceCollection services, System.Collections.Generic.IEnumerable<Microsoft.Extensions.DependencyInjection.ServiceDescriptor> descriptors);

static member TryAddEnumerable : Microsoft.Extensions.DependencyInjection.IServiceCollection * seq<Microsoft.Extensions.DependencyInjection.ServiceDescriptor> -> unit

<Extension()>
Public Sub TryAddEnumerable (services As IServiceCollection, descriptors As IEnumerable(Of ServiceDescriptor))

参数

services

IServiceCollection

IServiceCollection

descriptors

IEnumerable<ServiceDescriptor>

ServiceDescriptor。
