Answer 1

//create image source
                //System.Windows.Media.Imaging.
                bool noLoadImageErr = true;
                BitmapImage myBitmapImage = new BitmapImage();
                try
                {
                    // BitmapImage.UriSource must be in a BeginInit/EndInit block
                    myBitmapImage.BeginInit();
                    myBitmapImage.StreamSource = new System.IO.MemoryStream((byte[])drP["image1"]);
                    //myBitmapImage.DecodePixelWidth = 60;
                    myBitmapImage.EndInit();
                }
                catch
                {
                    noLoadImageErr = false;
                    try
                    {
                        myBitmapImage = ImageFromGDIplus((byte[])drP["image1"]);
                    }
                    catch                    
                    {
                        noLoadImageErr = false;
                    }
                }
                if (noLoadImageErr)
                {
                    img1.Source = myBitmapImage;
                    myBitmapImage = null;
                    this.DragProductList1.Items.Add(img1);
                }

Answer 2

byte[] byteArrayIn
MemoryStream ms = new MemoryStream(byteArrayIn);
Image  returnImage = Image.FromStream(ms);

Answer 3

   public Image byteArrayToImage(byte[] byteArrayIn)
        {
            MemoryStream ms = new MemoryStream(byteArrayIn);
            Image returnImage = Image.FromStream(ms);
            return returnImage;
        }

Answer 4

if (!dr.IsNull("图片"))
                {
                    byte[] data = new byte[0];
                    data = (byte[])dr["图片"];
                    int bmpSize = new int();
                    bmpSize = data.Length;
                    MemoryStream ms = new MemoryStream();
                    ms.Write(data,0, bmpSize);
                    Bitmap bmp;
                    bmp = new Bitmap(ms);
                    picbox.Image = bmp;
                }
