Question

I’ve always wondered this. In C#, when do instance variables with default values get set – before or after the constructor?

For this code:

public class Foo
{
  public int bar=1;
  public Foo()
  {
    bar = 2;
  }
}
...
Console.WriteLine(new Foo().bar);

Would it output 1 or 2?

Answer 1

The instance during construction will run through all declarations first then proceed into the constructor itself.

Thus, bar = 1 will execute before bar = 2 but the end result will still be bar = 2.
