I just declared a variable like this: bool b = (x is Foo) ?

  • 0

I just declared a variable like this:

bool b = (x is Foo) ? (x as Foo).Bar == 1 ? false;

But resharper told me that I could simplify the expression, so I rewrote it like this:

bool b = (x as Foo).Bar == 1;

Amd now resharper is satisfied, but is “exception safe”? For example, will it return false if x isnt of the type Foo?

    The second will throw a NullReferenceException if x isn’t of the type Foo
