The ServiceProvider type exposes the following members.

Constructors

	Name	Description
	ServiceProvider()	Class constructor for a managed service provider (IServiceProvider) that is accessible through the unmanaged IServiceProvider interface.
	ServiceProvider(IServiceProvider)	Class constructor for wrapping an unmanaged IServiceProvider interface that is accessible through the managed IServiceProvider interface.

Properties

	Name	Description
	ServiceTypes	Retrieves a list of service types used to convert the unmanaged QueryService method call, in which a service GUID is specified, into a managed IServiceProvider.GetService method call, in which a managed type is specified.

Methods

	Name	Description
	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 the default hash function. (Inherited from Object.)
	GetService(Guid)	Retrieves a service with a specified service GUID.
	GetService(Type)	Retrieves a service of the specified type.
	GetServiceImpl(Guid)	Provides the implementation for retrieving a service with a specific GUID.
	GetServiceImpl(Type)	Provides the implementation for retrieving a service of a specific type.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations

	Name	Description

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) is IServiceProvider interface and the second (managed) is IServiceProvider.

This class serves two purposes. First, it provides a managed wrapper around the unmanaged IServiceProvider interface. Second, it provides a managed base class for implementing the unmanaged IServiceProvider interface.

For both cases, the managed IServiceProvider interface is also implemented, so managed clients of the object can communicate with the object 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.
