Why there's no modifiers (public, private, protected) in front of methods and properties defining an interface?

<p>Hello,</p>

<p>I'm curious about interfaces. Let's say I've the following interface's definition</p>

<pre><code>public interface IPersone
{
  string FirstName { get; set; }
  string LastName { get; set; }
  int CalculateAge(int YearOfBirth);
}
</code></pre>

<p>Why there's no modifiers (public, private, protected) in front of methods and properties defining an interface? Is there any reason for that?</p>

<p>Thanks for helping  </p>
