I have a quick question about Attributes

When we use the Description attribute we normaly do it like this

[Description("Class that contains information about an user")]
public class user

But how come we can construct the type like Description("") and DescriptionAttribute("") ???
i mean, i can't seem to find the class called Description, when i look with the object browser, but the DescriptionAttribute is there.[confused][confused]

I have been looking on MSDN, but nothing seems to popup about this.

Anyone have a answer [D'Oh] [D'Oh]

From MSDN (http://msdn.microsoft.com/en-us/library/bfz783fz.aspx):

"By convention, all attribute names end with Attribute. However, several languages that target the runtime, such as Visual Basic and C#, do not require you to specify the full name of an attribute. For example, if you want to initialize System..::.ObsoleteAttribute, you only need to reference it as Obsolete."

Solution 1

stuff surrounded by "[" and "]" are not normal classes. They are class attributes and can be used hundreds of different ways...

Look here for more info: http://www.codeproject.com/KB/cs/attributes.aspx[^]

Hello Paw,

* I can see that the question is 5 years old ;) , but I've just happened to read it now...

See DescriptionAttribute Class
on MSDN[^]

You can see this CP article on Attributes in C# in general (it's a little old but it's ok):
Attributes in C#[^]

Cheers,
Edo
