Silverlight的4.0：如何字节[]转换为图像？ [英] Silverlight 4.0: How to convert byte[] to image?

问题描述

public Image Base64ToImage(string base64String)
    {
        // Convert Base64 String to byte[]
        byte[] imageBytes = Convert.FromBase64String(base64String);
        MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length);

        // Convert byte[] to Image
        ms.Write(imageBytes, 0, imageBytes.Length);
        System.Drawing.Image image = System.Drawing.Image.FromStream(ms, true);
        return image;
    }

我想转换字节[]以影像，但System.Drawing.Image对象不支持Silverlight。任何替代方案？

I want to convert byte[] to image, however System.Drawing.Image is not supported in Silverlight. Any alternative?

推荐答案

您需要创建的ImageSource并分配到一个图像控件或使用的ImageBrush在后台设置。 BitmapImage的位于System.Windows.Media.Imaging命名空间。

You need to create an ImageSource and assign that to an Image control or use an ImageBrush to set on the background. BitmapImage is located in the System.Windows.Media.Imaging namespace.

        byte[] imageBytes = Convert.FromBase64String(base64String);
        using (MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length))
        {
            BitmapImage im = new BitmapImage();
            im.SetSource(ms);
            this.imageControl.Source = im;
        }

或用于的ImageBrush

or for the ImageBrush

        byte[] imageBytes = Convert.FromBase64String(base64String);
        using (MemoryStream ms = new MemoryStream(imageBytes, 0,
          imageBytes.Length))
        {
            BitmapImage im = new BitmapImage();
            im.SetSource(ms);
            imageBrush.ImageSource = im;
            this.BoxBorder.Background = imageBrush;
        }
