silverlight-4.0 – Silverlight 4.0：如何将byte []转换为image？

public Image Base64ToImage(string base64String)
    {
        // Convert Base64 String to byte[]
        byte[] imageBytes = Convert.FromBase64String(base64String);
        MemoryStream ms = new MemoryStream(imageBytes,imageBytes.Length);

        // Convert byte[] to Image
        ms.Write(imageBytes,imageBytes.Length);
        System.Drawing.Image image = System.Drawing.Image.FromStream(ms,true);
        return image;
    }

我想把byte []转换成image，但是在Silverlight中不支持System.Drawing.Image。任何选择？

解决方法

您需要创建一个ImageSource并将其分配给Image控件或使用ImageBrush在背景上设置。 BitmapImage位于System.Windows.Media.Imaging命名空间中。

byte[] imageBytes = Convert.FromBase64String(base64String);
        using (MemoryStream ms = new MemoryStream(imageBytes,imageBytes.Length))
        {
            BitmapImage im = new BitmapImage();
            im.SetSource(ms);
            this.imageControl.source = im;
        }

或ImageBrush

byte[] imageBytes = Convert.FromBase64String(base64String);
        using (MemoryStream ms = new MemoryStream(imageBytes,imageBytes.Length))
        {
            BitmapImage im = new BitmapImage();
            im.SetSource(ms);
            imageBrush.ImageSource = im;
            this.BoxBorder.Background = imageBrush;
        }
