If you have supplied the lines of code that are throwing, and Name is a string, then genre is null.


You make sure genre is not null. The most likely solution to you problem is to skip the link creation there are a few ways to do this, but I'm not sure which'll work in Razor. this should be safe:

@foreach (var genre in Model)
{
     if(genre != null)
     {
         @Html.ActionLink(genre.Name,"Browse",new {genre=genre.Name})
     }
}

if you want to be really belt & braces and avoid any empty links

@foreach (var genre in Model)
{
     if(genre != null && !string.IsNullOrWhiteSpace(genre.Name))
     {
         @Html.ActionLink(genre.Name,"Browse",new {genre=genre.Name})
     }
}

Of course, the last example is only good if Name is a string.

The other thing you should check is the code that fills Model, the chance are there shouldn't be any nulls in there.
