Retrieves a binary or raw field as an array of bytes.
public byte[] GetBytes( int columnNumber );
This method retrieves the specified zero-based column value as an array of bytes. No conversions are performed; therefore the data retrieved must already be a byte array (raw field or BLOB field). This method cannot be used to retrieve null values. Call AdsDataReader.IsDBNull to check for null values before calling this method.
