  <p>Hi,</p>
  
  <p>I'm creating a json string. I have some json encoders that receive objects and return json string. I want to assemble these strings into one long string.</p>
  
  <p>What's the difference between using a string builder and declaring a string an appending strings to it.</p>
  
  <p>Thanks.</p>
