What does the [] represent in C#

Question

i've been developing in c# for 4 month and I still dont know what does the [] means in entity framework.

Here an example

[Column("mycolumn")]
public int Column {get;set;}

What is it functionality?

Its there another situation that i have to use it or just with entity framework?

it varies, depending on context. In your context you are adorning a property with an attribute. In other contexts you could be accessing an indexer or dimensioning an array. — Jodrell, May 21 '13 at 15:34
Technically its a question about square brackets, which just happen to be generally (solely?) used for attributes. — Meirion Hughes, May 21 '13 at 15:39
You just cannot asked a question that you dont know. Really cool — Ligth, May 21 '13 at 16:07

Square brackets [ & ] mean a few different things in C#, but in this case they are saying that "Column" is an Attribute. An attribute is basically design time information that you add to classes or properties for various reasons. You can also make your own ;)

`design time information` ??? – I4V May 21 '13 at 15:36
yeah - as in information you add to classes when you are designing them - not loaded in at runtime from some external source. Sorry I don't know the proper word lol – jcharlesworthuk May 22 '13 at 09:43
