Returns the value of the specified column as a byte array.

 abstract long GetBytes(int i, long dataIndex, cli::array <System::Byte> ^ buffer, int bufferIndex, int length);

public:
 virtual long GetBytes(int i, long dataIndex, cli::array <System::Byte> ^ buffer, int bufferIndex, int length);

public abstract long GetBytes(int i, long dataIndex, byte[]? buffer, int bufferIndex, int length);

public abstract long GetBytes(int i, long dataIndex, byte[] buffer, int bufferIndex, int length);

public long GetBytes(int i, long dataIndex, byte[] buffer, int bufferIndex, int length);

abstract member GetBytes : int * int64 * byte[] * int * int -> int64

Public MustOverride Function GetBytes (i As Integer, dataIndex As Long, buffer As Byte(), bufferIndex As Integer, length As Integer) As Long

Public Function GetBytes (i As Integer, dataIndex As Long, buffer As Byte(), bufferIndex As Integer, length As Integer) As Long

Parameters

i: Int32

The zero-based column ordinal.

dataIndex: Int64

The index within the field from which to start the read operation.

buffer: Byte[]

The buffer into which to read the stream of bytes.

bufferIndex: Int32

The index for buffer to start the read operation.

length: Int32

The number of bytes to read.

Returns

Int64

The value of the specified column.

Implements

GetBytes(Int32, Int64, Byte[], Int32, Int32)

Remarks

No conversions are performed; therefore the data retrieved must already be a byte array.
