I'm looking to create an extension method with the following signature:
public static IObservable<DialogResult> ShowDialog(this Form form);
I don't know how to get this to work. This is what I have so far:
Task<DialogResult> task = Task.Factory.StartNew(() =>
{
return form.ShowDialog();
});
return task.ToObservable();
Edit: Cool, thanks guys. I really need to read up on this stuff some more!
I imagine this would work, though I don't understand the point.
public static class Extensions
{
public static IObservable<DialogResult> ShowDialogObservable(this Form form)
{
return Observable.Create<DialogResult>(o =>
{
o.OnNext(form.ShowDialog());
return Disposable.Empty;
});
}
}
