The ServiceProvider type exposes the following members.

Constructors

	Name	Description
	ServiceProvider()	Initializes a new instance of a managed or unmanaged IServiceProvider.
	ServiceProvider(IServiceProvider)	Wraps an unmanaged IServiceProvider interface that is accessible through the managed IServiceProvider interface.
	ServiceProvider(IServiceProvider)	Initializes a new instance of an unmanaged IServiceProvider interface.

Properties

	Name	Description
	ParentProvider	Gets the current instance of the parent service provider.

Methods

	Name	Description
	AddService(Type, ServiceCreatorCallback)	Adds the specified service to the internal collection of services.
	AddService(Type, Object)	Adds the specified service to the internal collection of services.
	AddService(Type, ServiceCreatorCallback, Boolean)	Adds the specified service to the internal collection of services or to the parent service container.
	AddService(Type, Object, Boolean)	Adds the specified service to the collection of service objects or to the parent service container.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetService(Guid)	Retrieves a service with a specified service GUID.
	GetService(Type)	Retrieves a service of the specified type.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RemoveService(Type)	Removes the specified service from the internal services collection
	RemoveService(Type, Boolean)	Removes the specified service from the internal services collection or from the parent service container.

Explicit Interface Implementations

Remarks

Note

In the syntax block above, the class inheritance derives from both the managed and the unmanaged IServiceProvider interfaces. That is, the first (unmanaged) derives from the IServiceProvider interface and the second (managed) derives from IServiceProvider.

This class serves two purposes. First, it provides a managed class for creating an implementation of the unmanaged or managed IServiceProvider interfaces. Second, it provides a managed class for wrapping and extending an existing implementation of the unmanaged or managed IServiceProvider interfaces.

For both cases, the managed IServiceProvider interface is also implemented, so managed clients of the object can communicate with the object by using managed-friendly code.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
