C# Correctly distinguish between bool? and bool [duplicate]

This question already has an answer here:

• Detect nullable type 6 answers

Probably a newb question but I am trying to find out if a variable is either a simple bool or a Nullable<bool>.

It seems that

if(val is Nullable<bool>)

returns true for both bool and Nullable<bool> variables and

if(val is bool)

also returns true for both bool and Nullable<bool>

Basically, I am interesting in finding out if a simple bool variable is true OR if a Nullable<bool> variable is not null.

What's the way to do this?
