title: Default value c# function but not the last
body: <p>Say I have a function</p>
  
  <pre><code>void func (int a = 0, int b = 1)
  {
       //do something
  }
  </code></pre>
  
  <p>and I want to give b a value, but not a</p>
  
  <pre><code>func( , 10);
  </code></pre>
  
  <p>I cannot change the func function, because I have not created it, is there a keyword to say: use default value for this parameter?     </p>
