怎样在vb.net中将图片存入SQL Server 2000并能读出来使用?

　　在数据库中建一个Img表,其中包含一个Img字段,类型为Image或Binary
　　'将Bytes存入数据库
　　Dim Stream As New IO.MemoryStream
　　PictureBox1.Image.Save(Stream, System.Drawing.Imaging.ImageFormat.Bmp)
　　Stream.Flush()
　　Dim Bytes As Byte() = Stream.ToArray
　　Dim SQL As String = "insert into Img values (@bytes) "
　　Dim command As New SqlClient.SqlCommand(SQL, Connection)
　　command.Parameters.Add("@bytes", SqlDbType.Binary).Value = Bytes
　　command.ExecuteNonQuery

　　'读取
　　Dim Command As New SqlClient.SqlCommand(SQL, Connection)
　　Dim Reader As SqlClient.SqlDataReader = Command.ExecuteReader()
　　Dim Bytes as Byte()=Reader.Item("Img")
　　Dim mStream As New IO.MemoryStream
　　mStream.Write(Bytes, 0, Bytes.Length)
　　mStream.Flush()
　　Dim Img As New Bitmap(mStream)
　　PictureBox1.Image = Img
