How to include multiple Css Class in ActionLink?

Problem :

Let's say I have two Css class like below:

     .btn
     {
          border:1px solid yellow;
     }

     .btn-info
     {
          background-color: blue;
     }

and an ActionLink:

     <li>@Html.ActionLink("Home", "Index", "Home", new { @class = "btn btn-info" })</li>

As you can see I included those css class in ActionLink classes but it takes only first one. How should I add second one to ActionLink Css classes.

Generated Html:

     <a class="btn btn-info" href="/"></a>

Solution :

<li>@Html.ActionLink("Home", "Index", "Home", null, new { @class = "btn btn-info" })</li>

The fourth parameter is for the routeValues and the fifth parameter is for htmlAttributes.
