如何在水晶报表中显示图片?数据存储在sql sqerver2000的image字段中,代码:
 SaveImg(picelimg.Image, "insert into zmlquote01d1(barcode,elimg) values('" + NeonBaseFun.AddComma(txtbarcode.Text) + "',@elimg)", "@elimg", trans);        private void SaveImg(System.Drawing.Image img, string insert, string field, SqlTransaction trans)
        {
            byte[] imgdata;
            using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
            {
                Bitmap bmp = new Bitmap(img);
                bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Gif);
                imgdata = new byte[stream.Length];
                stream.Position = 0;
                stream.Read(imgdata, 0, (int)stream.Length);
                SqlCommand cmd = NeonConn.CreateCommand(insert);
                cmd.Transaction = trans;
                cmd.Parameters.Add(field, SqlDbType.Image);
                cmd.Parameters[field].Value = imgdata;
                cmd.ExecuteNonQuery();
                cmd.Dispose();
                bmp.Dispose();
            }
        }
有时图片会显示不出来,请问是什么原因?
