DbDataReader.GetBytes(Int32, Int64, Byte[], Int32, Int32) DbDataReader.GetBytes(Int32, Int64, Byte[], Int32, Int32) DbDataReader.GetBytes(Int32, Int64, Byte[], Int32, Int32) DbDataReader.GetBytes(Int32, Int64, Byte[], Int32, Int32) Method

Definition

When overridden in a derived class, reads a specified number of bytes from the specified column starting at a specified index and writes them to a buffer starting at a specified position in the buffer.

public:
 abstract long GetBytes(int ordinal, long dataOffset, cli::array <System::Byte> ^ buffer, int bufferOffset, int length);
public abstract long GetBytes (int ordinal, long dataOffset, byte[] buffer, int bufferOffset, int length);
abstract member GetBytes : int * int64 * byte[] * int * int -> int64
Public MustOverride Function GetBytes (ordinal As Integer, dataOffset As Long, buffer As Byte(), bufferOffset As Integer, length As Integer) As Long

Parameters

ordinal
Int32 Int32 Int32 Int32

The zero-based column ordinal.

dataOffset
Int64 Int64 Int64 Int64

The index within the row from which to begin the read operation.

buffer
Byte[]

The buffer into which to copy the data.

bufferOffset
Int32 Int32 Int32 Int32

The index with the buffer to which the data will be copied.

length
Int32 Int32 Int32 Int32

The maximum number of characters to read.

Returns

The actual number of bytes read.
