How to convert an input string to uppercase in c#
<pre><code>string choice = String.ToUpper(Console.ReadLine());
</code></pre>

<p>I want to input a string and convert it to upper case. However, there's an error that states : </p>

<blockquote>
  <p>cannot convert from 'string' to System.Globalization.CultureInfo'</p>
</blockquote>

<p>that appears when I hover over the <code>Console.ReadLine()</code>. Why doesn't this work , and what fixes are there? And is there another way to do this ?</p>
