Decoding a tag in ASP.NET MVC

I'd like to know if there is an alternative for this in ASP.NET MVC:

<input type="file" name="filePath" id="file" /> 

I would like to have it with some code sample:

<%= Html.TextAreaFor(m => m.FilePath,1,32,null)%>

Write your own Html helper, that will render this html code for you. You can use this tutorial or this video to get some knowledge about how to make it.
