enums

问题 is there a proper way to count elements of an enum in VBA ? At the moment, I leave an enum value such as KeepThisOneHere in the following example Enum TestEnum ValueA ValueB ValueC KeepThisOneHere End Enum I use the last value to know the size... I don't like this solution, because I am not sure I have a guarantee the values will always be indexed the same way, and the code might be changed by a third party who might add values after this last special one, silently breaking the rest of the

问题 I am working on a basic Battleship game to help my C# skills. Right now I am having a little trouble with enum. I have: enum game : int { a=1, b=2, c=3, } I would like the player to pass the input "C" and some code return the integer 3 . How would I set it up for it to take a string var ( string pick; ) and convert it to the correct int using this enum? The book I am reading on this is bit confusing 回答1: Just parse the string and cast to int. var number = (int)((game) Enum.Parse(typeof(game),

问题 I have just started learning C++, and am still new to the concepts of header files and the structure of classes. I have been learning Java for 2 years and the C++ syntax and some operations have different behaviors. I am trying to make a deck of cards. To make the code cleaner, I would like to use enumerations for my Suits and Values of the cards. However the problem in the Deck class is that I have a method to populate the deck with cards using a vector . I have researched and I now realize

问题 What is the quickest way to determine which members of an enum are not being used? 回答1: If you're using ReSharper, click on the enum to check, hit Alt+F7 (Shift+F12 if you're using VS shortcuts), and it'll give you a list of every place it's used in your entire solution. 回答2: Comment the enum members out one by one and see if your code compiles. If compilation breaks, the member is used. Although this method only catches compile-time use of your enums. They could be used at runtime. 回答3:

问题 To allow for different formatting options on a method that displays a news story, I've created an enumeration that can be passed in to specify how it gets displayed. [Flags] private enum NewsStyle { Thumbnail = 0, Date = 1, Text = 2, Link = 4, All = 8 } string FormatNews( DataRow news, NewsStyle style ) { StringBuilder HTML = new StringBuilder(); // Should the link be shown if ( ((newsStyle & NewsStyle.All) == NewsStyle.All || (newsStyle & NewsStyle.Link) == NewsStyle.Link)) { HTML
