Reads a stream of bytes from the specified column offset into the buffer an array starting at the given buffer offset.
public long GetBytes
(
int iCol, // (I) 0-based column index
long lFieldOffset, // (I) offset to start reading from
byte[] buffer, // (O) output buffer
int iBufferOffset,// (I) starting offset in output buffer
int iLength // (I) number of bytes to read
);
Return Value
The actual number of bytes read.
Remarks
If you pass a buffer that is a null reference (Nothing in Visual Basic), GetBytes returns the length of the field in bytes.
No conversions are performed; therefore the data retrieved must already be a byte array. This method cannot be used to retrieve null values. Call AdsDataReader.IsDBNull to check for null values before calling this method.
