The DataProviderObjectFactory type exposes the following members.

Constructors

Properties

	Name	Description
	DataProvider	Retrieves the DDEX provider for which this class creates objects.
	Site	Retrieves or sets the object site. (Inherited from ObjectWithSite.)

Methods

	Name	Description
	CreateObject	Creates a data-provider-written object that implements the specified object type.
	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.)
	GetAssembly	Locates an assembly given an assembly string.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance. (Inherited from Object.)
	GetType(String)	Retrieves a type definition given a type name.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnSiteChanged	Raises the SiteChanged event. (Inherited from ObjectWithSite.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	SiteChanged	Event that is raised when the Site property is changed. (Inherited from ObjectWithSite.)

Explicit Interface Implementations

	Name	Description
	IObjectWithSite.GetSite	Retrieves the last site set using the IObjectWithSite.SetSite method. In cases where there is no known site, the object returns an exception. (Inherited from ObjectWithSite.)
	IObjectWithSite.SetSite	Provides the site's pointer to the site object. (Inherited from ObjectWithSite.)

Remarks

Classes derived from DataProviderObjectFactory should implement the M:Microsoft.VisualStudio.Data.DataProviderObjectFactory.CreateObject(System.Type) method to create provider-written objects that implement the specified object type. Such classes can use the P:Microsoft.VisualStudio.Data.DataProviderObjectFactory.DataProvider property to retrieve information about the data provider for which it is creating objects. This is most useful when a derived class is a base class for a particular technology like ADO.NET.

The DataProviderObjectFactory class servers as the root class, architecturally, for establishing a data extensibility framework.

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.
