The DataSupport type exposes the following members.

Constructors

	Name	Description
	DataSupport(String, Assembly)	Initializes a new instance of the DataSupport class with an XML resource stored in a managed assembly.
	DataSupport(String, String)	Initializes a new instance of the DataSupport 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 a hash function for a particular type. (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.
	OpenSupportStream(CultureInfo)	Opens a stream of bytes representing the XML content for a specified culture.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

One of the fundamental design goals of DDEX is for each major feature area of extensibility to be controlled through data support XML supplied by the DDEX provider. For each such feature area, there is a class - for example, DataViewSupport or DataObjectSupport - that provides a way to supply a stream of XML for the feature.

There are a few standard places from which this stream of XML may come. It may be read from a managed resource compiled into an assembly, or from a file on disk. This base class implements methods that will automatically locate either, depending on which constructor is called.

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.
