Global Dispatcher in WinRT?

问题

I have some WP7 code that looks like this:

using System.Windows;
using System.Windows.Threading;

public static class GlobalDispatcher
{
    public static Dispatcher Current { get { return Deployment.Current.Dispatcher; } }
}

What is the equivalent in WinRT? Is there no globally accessible Dispatcher (or CoreDispatcher) object?

回答1:

You will want to use Window.Current.Dispatcher.

Just adding this as answer, as it better solves the problem in my opinion:

Window.Current is null if the application is not focused and thus will bring you in trouble when there is a user involved ;)

CoreApplication.MainView.CoreWindow.Dispatcher isn't null...

try this:

        var dispatcher = CoreApplication.MainView.CoreWindow.Dispatcher;
        await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        {
            try
            {
               //Your code here
            }
            catch (Exception ex)
            {
                HandleException(ex);
            }
        });
