Question

I’m programming a software using .NET FRAMEWORK 4.5 in METRO APPLICATIONS. I’m using the classes HttpClient and HttpResponseMessage to get the feeds from a RSS.

    private async Task<IList<FeedDataItem>> CreateRecipesAndRecipeGroups(string url)
    {
        HttpClient client = new HttpClient();
        HttpResponseMessage response = null;

        try
        {
            response = await client.GetAsync(url);
        }
        catch (Exception ex)
        {
            // here I need to load the last feeds loaded
        }
    }

As you can see in my code, for example if I don’t have internet, the program should load the previous or latest feeds.

Does you have idea about how can I fix this scenario?

Answer 1

serialize the last downloaded feed to disk, when no internet available load from disk Quickstart: Reading and writing a file (Metro style apps using C#/VB/C++ and XAML)
