c# - BindingFlags for abstract class? -

i'm trying find right bindingflags use when using getmethod abstract class.

public abstract class {     private void consoleoutput(string text)     {     } } 

i tried following, doesn't seem work:

this.gettype().getmethod("consoleoutput", bindingflags.nonpublic | bindingflags.declaredonly) 

bindingflags.nonpublic | bindingflags.instance 

even though class abstract, method still instance.
