Sorry for the silly question, but I came across the following C# code and I'm wondering what the [Flags] portion is and what it does.
[Flags]
public enum UserFlags
{
//...
}
Thank you in advance.

Invalid syntax is what I'd call it. – Andy Turner Feb 08 '17 at 09:48

2Looks like C#, not Java, in which case this is a called an `Attribute`. See https://msdn.microsoft.com/en-us/library/aa288454(v=vs.71).aspx – nbokmans Feb 08 '17 at 09:48

Are you certain it isn't C# code you came across? – Henrik Aasted Sørensen Feb 08 '17 at 09:48

3That is not Java; it looks like C#, where `[...]` is used for [annotations](https://docs.oracle.com/javase/tutorial/java/annotations/). In Java it would be `@Flags` instead of `[Flags]`. – Jesper Feb 08 '17 at 09:49

Thank you for the quick answers. Yes, it's C# indeed, my bad. I got this while searching for Java solutions so I didn't notice that it was C#. – Shadox Feb 08 '17 at 09:53

1@Jesper They're called attributes in C#. – shmosel Feb 08 '17 at 09:54

And just as an extra bit of information, the actual class name for that attribute is `FlagsAttribute`. The _Attribute_ portion of the class name can be omitted in code. – Chris Dunaway Feb 08 '17 at 17:21
