title: C# method to do URL encoding?
body: <p>what c# class method can I use to URL encode a URL string?</p>
  
  <p>In my use case I want to pass a URL string as a URL parameter itself.  So like burying a URL within a URL.  Without some encoding the "&amp;" and "?" characters in the inner URL can get picked up when the parameters for the outer Url parameters are processed</p>
  
  <p>thanks </p>
