title: Func<void> as input parameter
body: <p>I have method in c# with some parameters:</p>
  
  <pre><code>public static void DeleteSingleItemInDataGrid
      (DataGrid dataGrid, String IDcolumnName, Func&lt;int&gt; afterCompletionMethod_ToRun)
  </code></pre>
  
  <p>I want to change third parameter type to <code>Func&lt; void &gt;</code> but I can't. how can I do it?</p>
  
  <p>In other words <em>my question is how can pass a method(or function <strong>with void result</strong>) as a method parameter?</em> </p>
