In Index view I want to check if an object's parameter is null. I have done it as following code.

<td>            
    @if (String.IsNullOrEmpty(item.Account.Name) == false)
    {
        @Html.ActionLink(item.Account.Name, "../Accounts/Details", new { id = item.Account.AccountID })                
    }
    else
    {
        @Html.DisplayFor(modelItem => item.Account.Name)
    }
</td>

And I get this error:

{"Object reference not set to an instance of an object."}

So how should I check if the parameter in null?

1-ActionLink generates error if the object is null but DisplayFor does not.

2-This is in foreach loop in Index view.
