问题 I want to create a WinForms app that can detect location just like a web browser would using the javascript function navigator.geolocation.getCurrentPosition(showPosition); Is there some way to do this in WinForms directly? I thought that I might be able to use the WebBrowser control to do this but I don't believe this supports Geolocation (unless someone knows otherwise?)

问题 Take this: int? item1 = null; int? item2 = null; someObjectList.Where(x => x.SomeItem1 == (item1 ?? x.SomeItem1) && x.SomeItem2 == (item2 ?? x.SomeItem2) ); Where someObjectList is not empty and SomeItem1 and SomeItem2 is null in all the objects in the list. Why is it returning nothing? EDIT: My Code: public void GetPlacementsByMaterial(long clientMaterialID) { ClientMaterial clientMaterial = ((ApplicationEntityModel)NavigationItem.ObjectContext).ClientMaterial.FirstOrDefault(x => x

问题 I am just new to this world of asynchronous stuff. Please bear with my lack of knowledge. It is said when a method encounters await ... " It tells the awaitable to run the remainder of the method when it completes, and then returns from the async method. " I did not get this part.
