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. (Inherited from ServiceProvider.)
	Site	Retrieves or sets the site object instance.

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

Explicit Interface Implementations

	Name	Description
	IObjectWithSite.GetSite	Retrieves the last site set using the IObjectWithSite.SetSite method. If there is no known site, an exception is thrown.
	IServiceProvider.QueryService	Performs as a factory for services that are exposed through an implementation of IServiceProvider. (Inherited from ServiceProvider.)
	IObjectWithSite.SetSite	Provides a site's IUnknown pointer to a given object.

Remarks

This object essentially provides multiple inheritance from both the ServiceProvider and the ObjectWithSite classes. It actually inherits from the ServiceProvider class and has an IObjectWithSite object as a member variable, to which it delegates the implementation of IObjectWithSite.

This class is useful as a base class for any class that needs to be a service provider that is also able to be sited.

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.
