title: Get selected value from combo box in C# WPF
body: <p>I have just started using WPF forms instead of Windows Forms forms. In a Windows Forms form I could just do:</p>
  
  <pre><code>ComboBox.SelectedValue.toString();
  </code></pre>
  
  <p>And this would work fine.</p>
  
  <p>How do I do this in WPF? It doesn't seem to have the option.</p>
