OracleDataReader.GetBytes Method

public override long GetBytes (
	int i,
	long fieldOffset,
	byte[] buffer2,
	int bufferoffset,
	int length
)

public long GetBytes (
	int i, 
	long fieldOffset, 
	byte[] buffer2, 
	int bufferoffset, 
	int length
)

public override function GetBytes (
	i : int, 
	fieldOffset : long, 
	buffer2 : byte[], 
	bufferoffset : int, 
	length : int
) : long

Parameters

i

The zero-based column ordinal.

fieldOffset

The index within the field where the read operation is to begin.

buffer2

The buffer into which to read the stream of bytes.

bufferoffset

The index where buffer is to begin the write operation.

length

The number of bytes to read.

Return Value

GetBytes returns the number of available bytes in the field. In most cases this is the exact length of the field. However, the number returned may be less than the true length of the field if GetBytes has already been used to obtain bytes from the field. This may be the case, for example, if the OracleDataReader is reading a large data structure into a buffer. For more information, see the SequentialAccess setting of CommandBehavior.

If you pass a buffer that is a null value, GetBytes returns the length of the field in bytes.
