我在数据库（IBM DB2）中有一列“内容”（BLOB数据）和一个记录的数据相同，（https://drive.google.com/file/d/12d1g5jtomJS-ingCn_n0GKMsM4RkdYzB/view?usp=sharing）我已经通过编辑器打开了它，我认为它在这个（https://i.stack.imgur.com/2biLN.png，https://i.stack.imgur.com/ZwBOs.png）中有多个图像。
我可以将图像从字节数组（使用C#）导出到磁盘，但对于多个图像，我不知道如何操作。
请帮帮我！谢谢！
编辑1：我已经尝试导出它作为只有一个图像通过这个代码：

private void readBLOB(DB2Connection conn, DB2Transaction trans)
    {
        try
        {
            string SavePath = @"D:\\MyBLOB";
            long CurrentIndex = 0;
            //the number of bytes to store in the array  
            int BufferSize = 413454;

            //The Number of bytes returned from GetBytes() method  
            long BytesReturned;

            //A byte array to hold the buffer  
            byte[] Blob = new byte[BufferSize];

            DB2Command cmd = conn.CreateCommand();

            cmd.CommandText = "SELECT ATTR0102500126 " +
                              "  FROM JCR.ICMUT01278001 " +
                              "  WHERE COMPKEY = 'N21E26B04900FC6B1F00000'";
            cmd.Transaction = trans;

            DB2DataReader reader;
            reader = cmd.ExecuteReader(CommandBehavior.SequentialAccess);

            if (reader.Read())
            {
                FileStream fs = new FileStream(SavePath + "\\" + "quang canh.jpg", FileMode.OpenOrCreate, FileAccess.Write);
                BinaryWriter writer = new BinaryWriter(fs);

                //reset the index to the beginning of the file
                CurrentIndex = 0;

                BytesReturned = reader.GetBytes(
                    0, //the BlobsTable column index
                    CurrentIndex, // the current index of the field from which to begin the read operation
                    Blob, // Array name to write the buffer to
                    0, // the start index of the array
                    BufferSize // the maximum length to copy into the buffer
                    );

                while (BytesReturned == BufferSize)
                {
                    writer.Write(Blob);
                    writer.Flush();

                    CurrentIndex += BufferSize;
                    BytesReturned = reader.GetBytes(0, CurrentIndex, Blob, 0, BufferSize);
                }

                writer.Write(Blob, 0, (int)BytesReturned);
                writer.Flush(); writer.Close();

                fs.Close();
            }
            reader.Close();
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }
