ImageError error #4001 in control 'Xaml1': AG_E_NETWORK_ERROR 异常

 

这里的绑定是没有问题的，问题在于绑定发生在你设置DataContext之前，所以Image路径还没有设置成你期望的值。

 

一种解决方法是在xaml中去掉 Source="{Binding ProductImage}"

然后再你通过WebService取到Product以后再把这个Binding 加上。

Something like this:

 

 

 

Code Snippet

private void ResponseReady(IAsyncResult asyncResult)
        {
            WebRequest request = asyncResult.AsyncState as WebRequest;
            WebResponse response = request.EndGetResponse(asyncResult);
            using (Stream responseStream = response.GetResponseStream())
            {

                DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(ProductList));
                ProductList productList = jsonSerializer.ReadObject(responseStream) as ProductList;
                new Thread(() => {
                    mygrid.Dispatcher.BeginInvoke(
                        () =>
                        {
                            mygrid.DataContext = productList.Products[0];

                         Binding binding = new Binding("ProductImage");
                         rect.SetBinding(Image.SourceProperty, binding);
                        }

                        );
                }).Start();
            }
