title: Concatenate a constant string to each item in a List<string> using LINQ
body: <p>I am using C# and .Net 4.0. </p>
  
  <p>I have a <code>List&lt;string&gt;</code> with some values, say x1, x2, x3. To each of the value in the <code>List&lt;string&gt;</code>, I need to concatenate a constant value, say "y" and get back the <code>List&lt;string&gt;</code> as x1y, x2y and x3y. </p>
  
  <p>Is there a Linq way to do this?</p>
