Getting a Type Assembly in Windows 8

阅读更多关于 Getting a Type Assembly in Windows 8

问题 I'm trying to use MEF in Windows 8. In order to build up my AssemblyCatalog for the container, I need a reference to the assembly. In the past, I would have just done this: var catalog = new AssemblyCatalog(typeof(App).Assembly); Mysteriously, the Assembly property no longer exists on the Type object. Anybody know of a good work around? Is there another way to get the assembly? I could load it using Assembly.Load , but I would need the name of the assembly. I can't get that from the type

问题 Is this the correct/only way of getting a Stream from a resource file? Uri uri = new Uri(fullPath); StorageFile storageFile = await Windows.Storage.StorageFile. GetFileFromApplicationUriAsync(uri); IRandomAccessStreamWithContentType randomAccessStream = await storageFile.OpenReadAsync(); IInputStream resourceStream = (IInputStream) randomAccessStream.GetInputStreamAt(0); All my other sources (http and local storage) return a Stream object, and it is painful to have to if-else code that uses

问题 My Visual Studio can't seem to build any of the Metro Sample applications. As I've never really used this IDE before, I've pretty much given up. Can anyone direct me to a sample application that is already built and preferably some source code along with it for reference? Note: I have a copy of Windows 7 AND 8. However I can't seem to build Microsoft's File Access Sample in my copy of Visual Studio 2010 Ultimate. I'm trying to test one of my Win7 applications in Metro mode of Win8 (the

In metro, get all inherited classes of an (abstract) class?

阅读更多关于 In metro, get all inherited classes of an (abstract) class?

I got stuck when trying to get all inherited classes in metro. The WinRT API is different from .net framework, so both the solutions ( solution1 and solution2 ) don't work. Any code or tool solution is appreciated. I'm still trying. I will put my solution here if success. Damir Arh This should work (based on the code from here ): public IEnumerable<T> GetEnumerableOfType<T>(params object[] constructorArgs) where T : class, IComparable<T> { List<T> objects = new List<T>(); foreach (Type type in typeof(T).GetTypeInfo().Assembly.ExportedTypes .Where(myType => myType.GetTypeInfo().IsClass &&
