Question

Which way is better practice: return a value from a method inside an using statement or declare a variable before, set it inside and return it after?

public int Foo()
{
  using(..)
  {
     return bar;
  }
}

or

public int Foo()
{
  var b = null;
  using(..)
  {
    b = bar;
  }
  return b;
}

Answer 1

I prefer the first example. Fewer variables, fewer lines of code, easier to follow, easier to maintain…

public int Foo()
{
  using(..)
  {
     return bar;
  }
}
