[原] XAF 如何将数据库中Byte array图片显示出来

问题比较简单，直接上代码.

private Image _Cover;        [Size(SizeAttribute.Unlimited), ValueConverter(typeof(ImageValueConverter))]
public Image Cover
        {
get
            {
if (_Cover == null && _Photo != null && _Photo.Length > 0)
                {
using (MemoryStream stream = new System.IO.MemoryStream(_Photo))
                    {
                        System.Drawing.Image image = System.Drawing.Image.FromStream(stream);
                        _Cover = image;
return _Cover;
                    }
                }
return _Cover;
            }
set
            {

                SetPropertyValue("Cover", ref _Cover, value);

            }
        }


private Byte[] _Photo;
//[Delayed]
public Byte[] Photo
        {
get
            {
return _Photo;
            }
set
            {
//byte[] imagedata = null;
//if (Cover != null)
//{ 
//    MemoryStream ms = new MemoryStream();                
//    Image im = new Bitmap(Cover);
//    im.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
//    imagedata = ms.GetBuffer();
//    _Photo = imagedata;
//}
                SetPropertyValue("Photo", ref _Photo, value);
            }
        }

 XAF自带，varbinary(Max)类型图片操作方法：

   Image fPhoto;
        [ValueConverter(typeof(ImageValueConverter)), Delayed]
public Image Photo
        {
get { return fPhoto; }
set { SetPropertyValue("Photo", ref fPhoto, value); }
        }
