Access to attribute values from class of attribute
How do I retrieve the values of the attributes set on e.g. a class?

I have implemented a custom attribute, which is used for classes. Through the attribute it is possible to set different values. I want to get access to these values from within the class itself.

Is there a smart way of doing this, like accessing the values of an ordinary object?

Thanks, Jacob.

I found a way but I am not sure it is the easiest way or the most cost-effective way. Here is the solution I found...

using System;
using System.Reflection;

namespace Test
    public class MyCustomAttribute : Attribute
        public string item;

        public MyCustomAttribute()
            this.item = item;

    class MyClassWithTheAttributeApplied
        public static void SomeMethod()
            MemberInfo info = typeof(MyClassWithTheAttributeApplied);
            object[] o = info.GetCustomAttributes(true);
            foreach(object t in o)

    class MainClass
        static void Main(string[] args)

The above code will output myitemvalue. Please comment on the post if you know a better way to do this. Thanks.
