Yes. A "using" statement ends up being compiled as (essentially, not exactly):

try
{
   stream = File.Open(deleteListPath, FileMode.Open)
}
finally
{
   stream.Dispose();
}

I also just took a look at the Stream base class inside of Reflector and Close() basically does this:

this.Dispose(true);
GC.SuppressFinalize(this);

So a call to both Close and Dispose turns out to not be necessary. One or the other is fine.
