title: how to check if List<string> exists all values in other List<string>
body: <p>I'm trying to figure out how to check if all values match other List values.</p>
  <p>Example:</p>
  <pre><code>List&lt;string&gt; foo = new List&lt;string&gt;() {&quot;banana&quot;,&quot;apple&quot;,&quot;coconut&quot;}
  List&lt;string&gt; bar = new List&lt;string&gt;() {&quot;banana&quot;,&quot;apple&quot;,&quot;coconut&quot;,&quot;mango&quot;, &quot;lemon&quot;}
  </code></pre>
  <p>if every foo list item exists in bar then return true and if at least one is not in foo list then return false.
  AND if
  Example:</p>
  <pre><code>List&lt;string&gt; foo = new List&lt;string&gt;() {&quot;banana&quot;,}
  List&lt;string&gt; bar = new List&lt;string&gt;() {&quot;banana&quot;,&quot;apple&quot;,&quot;coconut&quot;,&quot;mango&quot;, &quot;lemon&quot;}
  </code></pre>
  <p>should return true</p>
  <p>AND if
  Example:</p>
  <pre><code>List&lt;string&gt; foo = new List&lt;string&gt;() {&quot;banana&quot;,&quot;melon&quot;}
  List&lt;string&gt; bar = new List&lt;string&gt;() {&quot;banana&quot;,&quot;apple&quot;,&quot;coconut&quot;,&quot;mango&quot;, &quot;lemon&quot;}
  </code></pre>
  <p>should return false</p>
  <p>AND if
  Example:</p>
  <pre><code>List&lt;string&gt; foo = new List&lt;string&gt;() {&quot;banana&quot;,&quot;apple&quot;,&quot;coconut&quot;,&quot;mango&quot;, &quot;lemon&quot;}
  List&lt;string&gt; bar = new List&lt;string&gt;() {&quot;banana&quot;}
  </code></pre>
  <p>should return false</p>
  <p>sory for all the changes. got to do this fast :D</p>
