title: Remove specific char in all strings in a list in c#
body: <p>I have some strings in a list they are</p>
  
  <pre><code>KHIJEFGACDB
  KHIJEFGBACD
  KHIJEFGBCDA
  KHIJEFGCDAB
  KHIJEFGCDBA
  KHIJGABCDEF
  KHIJGABEFCD
  KHIJGACDBEF
  KHIJGACDEFB
  KHIJGAEFBCD
  KHIJGAEFCDB
  KHIJGBACDEF
  KHIJGBAEFCD
  </code></pre>
  
  <p>I need to remove <code>HIJ</code> which is available in all strings in the list.</p>
  
  <p>I made a C# program like below</p>
  
  <pre><code>foreach (string item in items)
  {
      item.Replace("HIJ", "");
  }
  Console.WriteLine(items.FirstOrDefault().Length);
  </code></pre>
  
  <p>But its still displaying 11 that means the HIJ is not removed. How to solve this and get 8 as the answer.</p>
