is there a faq about the square bracket thingies in c#

[alexl]

hi,

is there a faq that explains what the square brackets are and what are
the available keywords you can use in them?

e.g.

[System.Security.Permissions.PermissionSet
(System.Security.Permissions.SecurityAction.Demand, Name="FullTrust")]
protected override void WndProc(ref Message m)
{

They're called attributes. A full description can be found here:

What you're seeing there is known as an Attribute. Documentation here:

Forgot to add: as far a getting a list of what's available for what...good
luck. I've never seen any documentation that says something like "This
class/function/whatever can be modifed with the following attributes: ..."
Your best bet is probably to look through a namespace and find any type with
"Atribute" on the end and then read its description.

But while it's good practice to name attribute classes ending in
"Attribute", it's not required. Better to use .NET Reflector to list all
classes inheriting from Attribute.
