title: Remove 'US' before '$' in currency displaying
body: <p>I'm using <code>.ToString("C")</code> method to show decimal number in currency format. But result looks lke <strong><em>"US$5,365.20"</em></strong> instead of <strong><em>"$5,365.20"</em></strong>.  I've tried to use <code>.ToString("C", new CultureInfo("en-US"))</code>, results the same. But when I've tried to use another culture (en-GB, for example) then everything was ok (<strong>£1,234.56</strong>). 
  <br><br>
  So, why "US" is appeared before "$" symbol? And how can I remove it?
  <br><br>
  <strong>UPD</strong> I'm sorry. Just checked it again, and i see, that with <code>new CultureInfo("en-US"))</code> all works perfectly, i looked on another label :) But now i see(thanks to @Mike McCaughan), that current currency symbol is "US$". Current culture name is 'en-US'.   </p>
