Question

I have a class with a definition of a private member like this:

[MyCustomAttribute]
private Func<String, String> MyFuncMember = (val) => val + " World! ";

and I’m trying to get the attribute that I put over it. Now, I have tried with Type.GetMembers(), Type.GetFields() and Type.GetMethods with the appropriate BindingFlags (BindingFlags.NonPublic) and I just cannot get that member. How can I retrieve it? Could it be a problem if the class where is defined is a sealed class?

Thanks in advance for you answers.

Answer 1

Try using this as your binding flags:

BindingFlags.NonPublic | BindingFlags.Instance

Without the BindingFlags.Instance flag it won’t be able to find your instance field.

In general when you use Type.GetField you need to set:

• one (or both) of BindingFlags.Instance and BindingFlags.Static

  and

• one (or both) of BindingFlags.Public and BindingFlags.NonPublic.

The | operator combines the flags using a binary or operation, meaning that both flags are set.
