问题 I'm new to using Dynamic Objects in C#. I am reading a CSV file very similarly to the code found here: http://my.safaribooksonline.com/book/programming/csharp/9780321637208/csharp-4dot0-features/ch08lev1sec3 I can reference the data I need with a static name, however I can not find the correct syntax to reference using a dynamic name at run time. For example I have: var records = from r in myDynamicClass.Records select r; foreach(dynamic rec in records) { Console.WriteLine(rec.SomeColumn); }

问题 I have class for iterating images. public class PictureManager { private int _current; public List<BitmapImage> _images = new List<BitmapImage>(5); public static string ImagePath = "dataImages"; public async void LoadImages() { _images = await GetImagesAsync(); } public async Task<List<BitmapImage>> GetImagesAsync() { var files = new List<BitmapImage>(); StorageFolder picturesFolder = await KnownFolders.PicturesLibrary.GetFolderAsync("dataImages"); IReadOnlyList<IStorageItem> itemsList =

问题 I'm trying to search for specific file name on all volumes on the system, except System Volume Information or Windows Directories and print out every full path for each file. I've tried to use Directory.GetFiles , but it only searche inside Drive C:\ or Drive D:\ (depends which drive is specified) How can I achieve my goal? For example I want to run program and search for file with name ".DS_Store" (used to use mac, and now my file system is full of these files....) I would really appreciate

My guess is that happens because client tries to find/use proxy from IE like it was with old HttpRequest/WebClient.
