Microsoft.VisualStudio.Data.Services Namespace

Artículo
10/07/2008

The Microsoft.VisualStudio.Data.Services namespace provides various services that allow clients to control the data connection by creating a new connection, or by providing a custom connection UI control, or by taking other actions. Furthermore, clients can have access to the data object mappings between the data source–specific metadata objects and the generic metadata. Also, this namespace contains services that define the hierarchical relationships between nodes in the data view. Note that, in addition to services, there are several interfaces that represent entities implemented internally as classes in DDEX, like for instance the IVsDataExplorerNode.

As part of the DDEX architecture, services are designed to consume support entities, which are defined in the Microsoft.VisualStudio.Data.Services.SupportEntities namespace. For instance, the IVsDataConnectionDialog service uses the IVsDataConnectionUIControl support entity, which allows the addition of a custom UI control for connection properties.

Classes

	Class	Description
	DataConnectionMessageReceivedEventArgs	Encapsulates the event data for the MessageReceived event for a data connection.
	DataConnectionOpenCanceledException	Represents the exception thrown when a data connection open call is canceled.
	DataConnectionStateChangedEventArgs	Encapsulates event data for the StateChanged event for a data connection.
	DataExplorerNodeEventArgs	Encapsulates the event data for the following events: NodeInserted, NodeChanged, NodeRemoving, and NodeExpandedOrRefreshed.
	DataMappedObjectTypeAttribute	Specifies that an interface or class represents a mapped object type. A mapped object type is an API that exposes a strongly-typed view of a particular underlying data source–specific object.
	DataObjectAddedEventArgs	Encapsulates event data for the ObjectAdded event.
	DataObjectChangedEventArgs	Encapsulates event data for the ObjectChanged event.
	DataObjectDeletedEventArgs	Encapsulates event data for the ObjectDeleted event.
	DataObjectEventArgs	Represents the base class for the following other classes that contain data object event data: DataObjectAddedEventArgs, DataObjectChangedEventArgs, and DataObjectDeletedEventArgs.
	DataProtection	Represents the ability to encrypt and decrypt strings by using the Windows Data Protection API (DPAPI).
