title: C# How to add string elements in array to string
body: <p>Need assistance to do this. Or advice about how to add string to string elements in array?</p>
  
  <ol>
  <li><p>We have 2 txt files with 100 or more strings in each:  </p>
  
  <p>domain.txt<br>
  domain1<br>
  domain2<br>
  ..<br>
  title.txt<br>
  title1<br>
  tilte2<br>
  .. </p></li>
  <li><p>and we have:</p>
  
  <p>string link = &lt; a h ref="http://www.domain.com" target="_blank">title&lt; /a></p></li>
  <li><p>After reading files we would have 2 string arrays - we need to replace domain.com with each string from domain.txt and title with each string from title.txt like this:  </p>
  
  <p>&lt; a h ref="http://www.domain1.com" target="_blank">title1&lt; /a><br>
  &lt; a h ref="http://www.domain2.com" target="_blank">title2&lt; /a><br>
  ..  </p></li>
  <li><p>Save the result string array into 2 txt files in that way: from 1-50 strings to<br>
  1.txt and from 50-100 to 2.txt file</p></li>
  </ol>
  
  <p>What is the best way to do this by manipulating strings with strings array elements?</p>
