title: find and delete tuple from list of tuples in C# 4.0
body: <p>I have created a list of tuples:</p>
  
  <pre><code>static List&lt;Tuple&lt;string, string&gt;&gt; Alt;
  </code></pre>
  
  <p>The user adds to this list: </p>
  
  <pre><code>Alt.Add(new Tuple&lt;string, string&gt;(tbAlt.Text, ""));
  </code></pre>
  
  <p>What is the best way to find a Tuple based on the first string (i.e. the tbAlt.Text ) and either delete it or modify the second string?</p>
  
  <p>I am new to using Tuples and lists :)</p>
  
  <p>Many thanks for any help!</p>
