) As Long

public long GetBytes( 
   long dataIndex,
   byte[] buffer,
   int bufferIndex,
   int length
)

Parameters

dataIndex

The specified column offset.

buffer

The specified buffer to read data to.

bufferIndex

The specified buffer offset.

length

The number of bytes to read.

Return Value

If the buffer parameter is null, GetBytes returns the length of the field in bytes.

If the CacheData property is false, applications can only retrieve the complete set of data from a DB2Blob instance once (by any of the ways): via the GetBytes method, Value property, or the ToString method. Tying to retrieve the current instance data again by any of the means results in System.InvalidOperationException.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
