程序集： Microsoft.SqlServer.Replication.BusinessLogicSupport（在 Microsoft.SqlServer.Replication.BusinessLogicSupport.dll 中）
语法
声明
Public Function GetBytes ( _
i As Integer, _
fieldOffset As Long, _
buffer As Byte(), _
bufferoffset As Integer, _

) As Long
用法
Dim instance As BusinessLogicDataReader
Dim i As Integer
Dim fieldOffset As Long
Dim buffer As Byte()
Dim bufferoffset As Integer
Dim length As Integer
Dim returnValue As Long
returnValue = instance.GetBytes(i, fieldOffset, _
buffer, bufferoffset, length)
public long GetBytes(
int i,
long fieldOffset,
byte[] buffer,
int bufferoffset,
int length
)
public:

参数
- i
类型：System.Int32
The zero-based column ordinal.
- fieldOffset
类型：System.Int64
The index within the row from which to begin the read operation.
- buffer
类型：array<System.Byte[]
The buffer into which to copy the data.
- bufferoffset
类型：System.Int32
The index with the buffer to which the data will be copied.
- length
类型：System.Int32
The maximum number of characters to read.
返回值
类型：System.Int64
The actual number of bytes read.
实现
IDataRecord.GetBytes(Int32, Int64, array<Byte[], Int32, Int32)
