推荐答案

很先打我从谷歌是一个的在Xamarin论坛线程讨论这一问题的确切：

The very first hit I got from Google was a thread on the Xamarin forums discussing this exact issue:

private Bitmap GetImageBitmapFromUrl(string url)
{
     Bitmap imageBitmap = null;

     using (var webClient = new WebClient())
     {
          var imageBytes = webClient.DownloadData(url);
          if (imageBytes != null && imageBytes.Length > 0)
          {
               imageBitmap = BitmapFactory.DecodeByteArray(imageBytes, 0, imageBytes.Length);
          }
     }

     return imageBitmap;
}

var imageBitmap = GetImageBitmapFromUrl("http://xamarin.com/resources/design/home/devices.png");
imagen.SetImageBitmap(imageBitmap);

这篇关于加载图像从URL到ImageView的 - C＃的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
