title: Where to store and how to access a connection string
body: <p>Where to add the connection string in a <code>C#</code> project? Like this string?</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;connectionStrings&gt;
      &lt;add name="strConn" 
           connectionString="Data Source=abc;Password=pass;User ID=user" 
           providerName="Oracle.DataAccess.Client"&gt;
      &lt;/add&gt;
  &lt;/connectionStrings&gt;
  </code></pre>
  
  <p>And how can I call it from my <code>program.cs</code> file?</p>
