title: Accessing Excel cells by name instead of "coordinates" like A1
body: <p>I have an Excel Sheet where I've named the cells I have to fill from my code.
  The reason for the named fields is that the customer has the possibility to re-arrange the cells.</p>
  
  <p>To make it a little clearer: I used the field shown below to name the cells.</p>
  
  <p><img src="https://i.stack.imgur.com/gjJyh.png" alt="Excel Field Name"></p>
  
  <p>My problem is now that I have no idea how to address these fields from C# using office interop.</p>
  
  <pre><code>Range r = Sheet.get_Range("M_Leitung", Type.Missing);
  </code></pre>
  
  <p>doesn't work. Since I don't have any ranges defined, just single cells where I have to insert the values, I'd need a function that returns the named cell.</p>
