The DataObjectSupport type exposes the following members.

Constructors

	Name	Description
	DataObjectSupport()	Class constructor. Instantiates a nonparameterized instance of the DataObjectSupport class.
	DataObjectSupport(String, Assembly)	Class constructor. Instantiates a parameterized instance of the DataObjectSupport class that provides means for locating a resource stream.
	DataObjectSupport(String, String)	Class constructor. Instantiates a parameterized instance of the DataObjectSupport class that provides resource directory information.

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.)
	GetDataObjectTypes	Retrieves an XML stream that contains information about a set of data object types that can be interpreted and manipulated programmatically.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetSupportStream	Obtains a Stream object instance for a specified culture. (Inherited from DataSupport.)
	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.)

Remarks

A data object type is a set of information that describes objects composing the structure of a data source—for example, a table or a data view. This information is provided in an XML stream (a Stream object) that conforms to the XML schema described in the VSDataObjectSupport.xsd file. For more information about this schema, see DDEX Data Object Support.

Implementing this object allows Visual Studio to access these objects programmatically without needing to rely on data-source-specific commands.

You must implement this class to use data tools with the data provider, including use of custom data view implementations that depend on programmatic access to data objects.

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.
