what are ["foo bar"] lines in c#?

So I'm coming over from Java, and I've been seeing (and using), a ton of these:

["foo bar"]
void method(param params)
{
     ..code things
}

Can someone explain to me what they are? I don't even know what they're called, so I can't manage to figure it out from documentation.

They are attributes. You can use them to decorate your code. The libraries providing the attributes usually use reflection to get this decorated (meta) information from your code at runtime.

For example, the XmlSerializer uses them a lot.

They are called Attributes.

There are many uses, such as:

  • Declare tests methods
  • Add description on enum values
  • Dependency Injection with MEF
  • You can do things with reflection

and so on.

They are called .NET Attributes. You can read about it for example here: What are attributes in .NET?
