Question

Code Snippet

                    byte[] b = result.Un_photo.ToArray();

                    if (b.Length > 0)
                        {
                       
                        MemoryStream stream = new MemoryStream();
                        int offset = 0;
                        stream.Write(b, offset, b.Length-offset);
                        System.Windows.Media.Imaging.BitmapImage img = new System.Windows.Media.Imaging.BitmapImage();
                        img.BeginInit();
                        img.StreamSource = stream;
                        img.EndInit();
                        Image_16.Source = img;
                        stream.Close();
                        }

 

 

Image_16是个image控件，用winform的gridview读数据库可成功读出图片，而用此方法当进行到img.EndInit();
时提示“无法对此图像进行解码。该图像头可能已损坏。”请问哪里的问题，该如何解决，谢谢，数据库中该图片的数据类型定义为image

Answer 1

不知道楼主的图片的格式是jpg还是什么？是否有可能是BitmapImage不支持你的图片格式啊？

  img.BeginInit();  这句前面加上stream.Seek(0, SeekOrigin.Begin);
