Properties

Descriptor	When implemented by a class, gets information that describes the data from a data source.
IsClosed	When implemented by a class, gets a Boolean value that indicates whether the specified reader is closed.
Status	When implemented by a class, gets a numerical status code returned by the method currently providing data to the data reader.

Methods

Close()	When implemented by a class, closes the IVsDataReader instance.
GetBytes(Int32, Byte[], Int32, Int32)	When implemented by a class, retrieves a specified number of bytes of raw binary data.
GetBytes(String, Byte[], Int32, Int32)	When implemented by a class, retrieves a specified number of bytes of raw binary data.
GetItem(Int32)	When implemented by a class, retrieves the value of the item at the specified index in the current block of data.
GetItem(String)	When implemented by a class, retrieves the value of a data item with the specified name in the current block of data.
IsNullItem(Int32)	When implemented by a class, indicates whether the data item at the specified index is unspecified, that is, null.
IsNullItem(String)	When implemented by a class, indicates whether the value of the given data item is unspecified, that is, null.
NextResult()	When implemented by a class, advances the data reader to the next result set, in cases where the reader contains multiple result sets.
Read()	When implemented by a class, advances the reader to the next block of data, in cases where the reader contains more than one block of data.
Terminate()	When implemented by a class, terminates the data reader immediately, without necessarily returning all of the data or setting output parameters.
