参数
- ordinal
类型：System.Int32
The zero-based ordinal position of the column to be retrieved.
- dataIndex
类型：System.Int64
The zero-based index within the column from which to begin reading data.
- buffer
类型：array<System.Byte[]
The buffer into which to read the stream of bytes.
- bufferIndex
类型：System.Int32
The zero-based index within the buffer from which to begin writing data.
- length
类型：System.Int32
The number of bytes to read from the column.
返回值
类型：System.Int64
A Long that contains the number of bytes actually read from the column.
实现
IDataRecord.GetBytes(Int32, Int64, array<Byte[], Int32, Int32)
