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.

The zero-based column ordinal.


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


The buffer into which to read the stream of bytes.


The index where buffer is to begin the write operation.


The number of bytes to read.

Return Value

The actual number of bytes read.

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.
