它会引发异常.有什么办法可以解决这个问题.

推荐答案

这是我发现的解决方案，并且有效:

Here's what I found as solution and it worked:

        WebClient client = new WebClient();
        client.OpenReadCompleted += (s, e) =>
            {
                if (e.Error == null)
                {
                    MediaLibrary library = new MediaLibrary();
                    library.SavePicture(imageName, e.Result);
                }
            };
        client.OpenReadAsync(new Uri(imageAbsoluteUrl, UriKind.Absolute));
