Get the attribute of a class within this class

[Michael]

Hello all,

using System;

namespace Test
{
[AttributeUsage(AttributeTargets.Class,
AllowMultiple = false)]
public class FactoryAttribute : System.Attribute
{
public string Identifier { get { return id_; } }
private string id_;

public FactoryAttribute(string identifier)
{
id_ = identifier;
}
}

[FactoryAttribute("MaladieLundi")]
class Foo
{
}
}

Is it possible IN Foo to get the value of the identifier of
FactoryAttribute?

thanks in advance

Mike

Yes,
do this in a method:
FactoryAttribute fa =
(FactoryAttribute)this.GetType().GetCustomAttributes(typeof(FactoryAttribute), false);

be warned though that enumerating custom attributes is very processing
intensive. It is possibly the slowest reflection operation.

OK, thank you for that answer.

And what is the way to do that from a static function?

Use typeof(YourClassNameHere) instead of this.GetType().
