DataObjectSupport Class

Enables you to retrieve an XML stream that describes a set of data object types on a data source, which you can then interpret and manipulate programmatically.

The DataObjectSupport type exposes the following members.

Constructors

	Name	Description
	DataObjectSupport(String, Assembly)	Instantiates a new instance of the DataObjectSupport class with an XML resource stored in a managed assembly.
	DataObjectSupport(String, String)	Instantiates a new instance of the DataObjectSupport class with an XML resource that is stored as a file at a specific file path on disk.

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.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OpenSupportStream()	Opens a stream of bytes representing the XML content. (Inherited from DataSupport.)
	OpenSupportStream(CultureInfo)	Opens a stream of bytes representing the XML content for a specified culture. (Inherited from DataSupport.)
	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 DataObjectSupport.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 the use of custom data view implementations that depend on programmatic access to data objects.

Inherits from the DataSupport class.

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.
