title: In WPF XAML how can I concatenate 2 constants so I can use pre-define paths?
body: <p>I want to replace the path part of the source path with a c# constant for easier path management, for example I have:</p>
  
  <pre><code>&lt;Image Source="/Images/Themes/Buttons/MyPicture.png" /&gt;
  </code></pre>
  
  <p>and in another class I have my constant defined:</p>
  
  <pre><code>public static readonly string UriImagesButtons = "/Images/Big/PNG/";
  </code></pre>
  
  <p>I want to have something along the lines of:</p>
  
  <pre><code>&lt;Image Source="{static:UriImagesButtons + MyPicture.png}" /&gt;
  </code></pre>
  
  <p>This means that I can change the path globally at a stroke if the need arises. What's the syntax to do this?</p>
