不是单行的，但您可以自己滚动几行.例如

Not a one-liner, but with very few lines you can roll your own. E.g.

static UIImage FromUrl (string uri)
{
    using (var url = new NSUrl (uri))
    using (var data = NSData.FromUrl (url))
        return UIImage.LoadFromData (data);
}

调用，包括来自 UIImage 的调用，都是线程安全的.

The calls, including the one from UIImage, are thread-safe.
