Hmm. The article says that the as operator is the same as casting, which is not correct. Casting will result in an exception if coercion fails, where as 'as' will return a null reference.

Which makes the code example

   (foo as Bar).Method();

dangerous without a guard.

Edit: punctuated for clarity.

You can always use the null coalescing operator.

(foo as Bar ?? new Bar()).Method();
