流转成image   
        while (reader.Read())
            {
                MemoryStream ms = new MemoryStream((byte[])reader["img"]);
                Image img = Image.FromStream(ms,true);
                this.BackgroundImage = img;                this.Text = Convert.ToString(i++);
                
            }

Answer 3

MemoryStream ms = new MemoryStream(data); 唉还有一句没打上呢这网速 没治了

Answer 4

System.Drawing.Bitmap objPic = new System.Drawing.Bitmap(“图片路径”);
MemoryStream ms = new MemoryStream();
objPic.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
ms里面就有图片了
