title: Multiplying all values in IEnumerable<int>
body: <p>I have the following code and I am trying to work out how to multiply all values in my <code>IEnumerable&lt;int&gt;</code>. </p>
  
  <p>I thought there might by a Multiply method like there is with Sum. I guess I could do a foreach over each item but these days this seems tedious.</p>
  
  <p>Any suggestions?</p>
  
  <pre><code>//1:2:6
  string[] pkgratio = comboBox1.SelectedRow.Cells["PkgRatio"].Value.ToString().Split(':');
  var ints = pkgratio.Select(x =&gt; int.Parse(x));         
  
  int modvalue = ints....
  </code></pre>
