Flags enumeration sample
I had to wrestle a bit to get an enumeration with the FlagsAttribute working correctly today so I though I'd just share my working code as a sample for some Google juice. If you want to download the code, you can do so
here. Hope this helps.
7 [Flags]
8 public enum HtmlParserOptions
9 {
10 NotifyOpeningTags = 1,
11 NotifyClosingTags = 2,
12 NotifyText = 4,
13 NotifyEmptyText = 8,
14 NotifyComments = 16,
15 All = NotifyOpeningTags | NotifyClosingTags | NotifyText | NotifyEmptyText | NotifyComments
16 }
17
18 class Program
19 {
20 HtmlParserOptions options = HtmlParserOptions.NotifyText;
21
22 static void Main(string[] args)
23 {
24 Program p = new Program();
25 p.Run();
26
27 Console.WriteLine("Press ENTER to exit");
28 Console.ReadLine();
29 }
30
31 public void Run()
32 {
33 Console.WriteLine(IsOptionSet(HtmlParserOptions.NotifyOpeningTags));
34 Console.WriteLine(IsOptionSet(HtmlParserOptions.NotifyClosingTags));
35 Console.WriteLine(IsOptionSet(HtmlParserOptions.NotifyText));
36 Console.WriteLine(IsOptionSet(HtmlParserOptions.NotifyEmptyText));
37 Console.WriteLine(IsOptionSet(HtmlParserOptions.NotifyComments));
38 Console.WriteLine(IsOptionSet(HtmlParserOptions.All));
39 }
40
41 private bool IsOptionSet(HtmlParserOptions singleOption)
42 {
43 return (options & singleOption) == singleOption;
44 }
45 }
