Question

Is it possible in C# in an attribute constructor to get the class that has the attribute assigned to it without having to pass that class name in.

    [MyAttr]
    public class A{}

    [AttributeUsage(AttributeTargets.Class, AllowMultiple = false)]
    [Serializable]
    public class MyAttrAttribute: Attribute
    {
        public MyAttrAttribute()
        {
           //get info here about the class A etc
        }    
    }

Answer 1

No. But why would you want to do this? What are you trying to achieve?

When you retrieve an attribute at run time, you do so from the type object representing the class. So even though the information is not stored in the attribute object, it is readily available.
