title: Getting configuration values rom XML file located in the same project
body: <p>I am making a little program to copy pictures form one location to another. The information for the pictures are stored in a database so I need connections string and also I create a txt file with the final output from the operation and I want to store these two values in a <code>App.Config.xml</code> file.</p>
  
  <p>The structure of my project is very simple :</p>
  
  <p><img src="https://i.stack.imgur.com/QZhoE.png" alt="Project Tree"> </p>
  
  <p>And the XML files itself is :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt;
  &lt;configuration&gt;
    &lt;connectionStrings&gt;
      &lt;add name="MyDB" connectionString="Data Source=.\\DVSQLEXPRESS08;Initial Catalog=**;Persist Security Info=True;User ID=**;Password=**;MultipleActiveResultSets=True" /&gt;
    &lt;/connectionStrings&gt;
    &lt;createResultFile&gt;
      &lt;add key="ResultFile" value="C:\Users\dv\Desktop\Leron\PictureStatus.txt"/&gt;
    &lt;/createResultFile&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>I want to use the <code>connectionString</code> and <code>&lt;createResultFile&gt;</code> value in my <code>PictureTransferTool.cs</code>. This is my first time working with XML file and C# (.NET in general) so I want what is the way to retrieve those config values?</p>
