title: How to Get WWWForm in a WEB API
body: <p>In my WebApi i have this POST-Method:</p>
  
  <pre><code>    [HttpPost]
      [EnableCors(origins: "*", headers: "*", methods: "*")]
      [Route("api/user/save")]
      public void Save([FromBody]string userinfo)
      {
          using (var context = new CarWarsEntities())
          {
              var a = "";
          }
      }
  </code></pre>
  
  <p>And i call it in my Unity Project with this code:</p>
  
  <pre><code>    var url = "http://localhost:61506/api/user/save";
      var form = new WWWForm();
      form.AddField("EXP", GameControl.control.EXP);
      form.AddField("Health", GameControl.control.Health);
      form.AddField("Silver", GameControl.control.Silver);
      form.AddField("Gold", GameControl.control.Gold);
      form.AddField("Ammo", GameControl.control.Ammo);
      form.AddField("Nitro", GameControl.control.Nitro);
      var www = new WWW(url, form);
  </code></pre>
  
  <p>The call worked, but the userInfo string is always null. How can i get the WWWForm Fields in my WebApi?</p>
