OracleDataReader.GetBytes Method

Reads a stream of bytes from the specified column offset into the buffer as an array, starting at the given buffer offset.

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

Public Overrides Function GetBytes ( _
	i As Integer, _
	fieldOffset As Long, _
	buffer2 As Byte(), _
	bufferoffset As Integer, _
	length As Integer _
) As Long
Dim instance As OracleDataReader 
Dim i As Integer 
Dim fieldOffset As Long 
Dim buffer2 As Byte()
Dim bufferoffset As Integer 
Dim length As Integer 
Dim returnValue As Long 

returnValue = instance.GetBytes(i, fieldOffset, _
	buffer2, bufferoffset, length)


Type: System.Int32

The zero-based column ordinal.

Type: System.Int64

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

Type: System.Byte()

The buffer into which to read the stream of bytes.

Type: System.Int32

The index where buffer is to begin the write operation.

Type: System.Int32

The number of bytes to read.

Return Value

Type: System.Int64
The number of bytes read.


IDataRecord.GetBytes(Int32, Int64, Byte(), Int32, Int32)

If you call GetBytes with a non-null buffer, the data is read into the buffer, and GetBytes will return the number of bytes that were read into the buffer.

If you call GetBytes with a null buffer, then no data is read, and GetBytes will return the number of bytes that are available to read. In most cases, this number is the full length of the field. However, if GetBytes has already been used to read bytes from the field, then the return value may instead be only the number of bytes remaining in the field. This may be the case, for example, if the OracleDataReader was created by using CommandBehavior.SequentialAccess.
