What is the equivalent of 'Is Nothing' ** RESOLVED **

I want to check to see if an object exists. In VB, I would have checked to see if the object Is Nothing. What is the correct way to determine this in C#?

Edit:

I didn't have the correct search criteria. I modified my search and found an answer.

For those subsequent views:

Code:

---

if (blah == null) {
    // Not instantiated.
}

---

Thanks axion_sa for posting the solution. It completely slipped my mind when I edited the post.

Thanks again.
