程序集：  Microsoft.SqlServer.ConnectionInfoExtended（在 Microsoft.SqlServer.ConnectionInfoExtended.dll 中）

语法

声明
Public Function GetBytes ( _
    ordinal As Integer, _
    fieldOffset As Long, _
    buffer As Byte(), _
    bufferoffset As Integer, _
    length As Integer _
) As Long
用法
Dim instance As TraceReader
Dim ordinal 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(ordinal, _
    fieldOffset, buffer, bufferoffset, _
    length)

public long GetBytes(
    int ordinal,
    long fieldOffset,
    byte[] buffer,
    int bufferoffset,
    int length
)

public:
virtual long long GetBytes(
    int ordinal, 
    long long fieldOffset, 
    array<unsigned char>^ buffer, 
    int bufferoffset, 
    int length
) sealed

abstract GetBytes : 
        ordinal:int * 
        fieldOffset:int64 *

override GetBytes :

public final function GetBytes(
    ordinal : int, 
    fieldOffset : long, 
    buffer : byte[], 
    bufferoffset : int, 
    length : int
) : long

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.

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)
