title: Increment "PropertyInfo SetValue"
body: <p>This is my code: </p>
  
  <pre><code>        Enemy ble = new Enemy();
          PropertyInfo prop = ble.GetType().GetProperty("x");
          prop.SetValue(ble,20, null);
          Console.WriteLine(prop.GetValue(ble));
  
  class Enemy
  {
      public int x { get; set; } = 20;
  }
  </code></pre>
  
  <p>As you can see I have an Enemy class and I've already found out how to find that property "x" and change it's value to set value, in my example 20, but my question is, how can I increment or decrement its value by 2 for example?</p>
