Question

I have created a custom attribute that I am using on my class MyClass. I would like to be able to reflect on an instance of this class to see information from that attribute.

Let’s say I have this class definition:

public class MyClass
{
   [Example("MyClassID")]
   public string ID;
}

Later in my code, I am using an instance of this class:

MyClass mc = new MyClass();
mc.ID = 18;

Is there a way I can get the attribute value (“MyClassID”) from this instance, mc? Ideally, I’d like to be able to tie this to my property, in a way similar to this:

mc.ID.GetCustomAttributes(typeof(ExampleAttribute), false)

Answer 1

Yes, you can do this through reflection:

this.GetType().GetProperty("ID").GetCustomAttributes(typeof(ExampleAttribute))

If this is not a property (which it isn’t in your example, but I wasn’t sure if that was a function of the question or not), then you can use GetMember.
