title: How to detect when arrow key down is pressed / C# WPF
body: <p>I'm working with WPF C# app, and I need to implement some action when arrow key down on keyboard is pressed, for example:</p>
  
  <pre><code>private void Window_KeyDown(object sender, KeyEventArgs e)
  {
      // Here I gotta check is that arrow key down which invoked this event.. then call a method
      DoSomething();
  }
  </code></pre>
