title: Web API parameter accept any parameter after valid one
body: <p>I have API that have one parameter string UserId a but while testing it accept any parameter after the parameter i have defined like this</p>
  
  <p><a href="http://localhost:xxxx/api/get?UserId=43141688" rel="nofollow noreferrer">http://localhost:xxxx/api/get?UserId=43141688</a> its shows the result I wanted and i have one parameter that is UserId but if I do like this</p>
  
  <p>"<a href="http://localhost:xxxx/api/get?UserId=43141688&amp;xyzpqr" rel="nofollow noreferrer">http://localhost:xxxx/api/get?UserId=43141688&amp;xyzpqr</a>  and also gets the same result on the basis of UserId
  and &amp;xyzpqr is not valid </p>
  
  <p>so how to do parameter binding basis of my parameter no additional (? and &amp; )include only UserId?</p>
  
  <p>What I have tried:</p>
  
  <p>I already tried attribute based routing and action-based routing </p>
