参数
- ordinal
类型：System.Int32
An Int32 value that specifies the column position from which to retrieve the byte array value.
- fieldOffset
类型：System.Int64
An Int32 value that specifies the index within the field from which to begin the read operation.
- buffer
类型：array<System.Byte[]
A Uint8 array into which to read the stream of bytes.
- bufferoffset
类型：System.Int32
An Int32 value that specifies the index at which to begin the read operation.
- length
类型：System.Int32
An Int32 value that specifies the number of bytes to read.
返回值
类型：System.Int64
An Int64 value that specifies the number of bytes returned in the array.
实现
IDataRecord.GetBytes(Int32, Int64, array<Byte[], Int32, Int32)
