title: How do I concatenate strings in c#
body: <p>I have a list of strings called people. I want to combine these and separate them with commas and store them in a variable called totalPeopleNames. This is what I have but it's not working:</p>
  
  <pre><code>string totalPeopleNames = null;
  
  foreach(var person in people)
  {
      Enumerable.Concat(totalPeopleNames, ", " + person.Person.FullName);
  }
  </code></pre>
