title: Define Powershell variable to have a value of a list
body: <p>I have some variables as below:</p>
  
  <pre><code>$a = "string1"
  $b = "string2"
  $c = "string3"
  </code></pre>
  
  <p>Now i want to define a variable $list to with all of the content from $a,$b,$c to look like this:</p>
  
  <pre><code>$list = "
  a: string1
  b: string2
  c: string3
  "
  </code></pre>
  
  <p>how can i do that?</p>
  
  <p>*** Edit: the content of the list must be EXACT like i wrote, that means, the part like "a: " b: ", ... must be the same too</p>
