C# Read (not write!) string from System.Net.Http.StringContent
<p>I have what seems like it should be a simple question, but I can't find an answer to it anywhere. Given the following code:</p>

<pre><code>    using System.Net.Http;
    ...
    StringContent sc = New StringContent("Hello!");
    string myContent = ???;
</code></pre>

<p>What do I need to replace the <code>???</code> with in order to read the string value from <code>sc</code>, so that <code>myContent = "Hello!"</code>?</p>

<p><code>.ToString</code> just returns System.String, as does <code>.ReadAsStringAsync</code>. How do I read out what I've written in?</p>
