c# - Can you omit the parenthesis from attributes with no params?

Question

I noticed when I have [Serializable] instead of [Serializable()], the code still compiles.

Is there a rule for this that you can omit the parentheses? Is it a good practice? It seems more readable to me unless I am missing something.

Answer 1

There's no particular rule regarding best practices that I've seen anywehere on the subect.

Generally, I find that people who hand-type their attributes omit the empty parens, but code generation almost always explicitly includes them.
