Best way to remove if statement inside view in asp.net MVC6

Consider the following code: 

@{
       if ((string) ViewContext.RouteData.DataTokens["area"] == "Guest"){                                                                              
             <text>areaNav_link--selected</text>
       }
}

How would I go about removing that if statement?

I prefer to use custom html helpers to remove logic.

As an example, you would call it as follows:

@Html.WelcomeText()

The logic could be moved into the helper as follows:

public static MvcHtmlString WelcomeText(this HtmlHelper htmlHelper)
{
    var text = string.Empty;
    var areaName = ViewContext.RouteData.Values["area"].ToString();

    if (areaName == "Guest")          
    { 
       text = "Hello Guest";
    }
    return new MvcHtmlString(text);
}

This way you could re-use it throughout the site with a single line of Razor code.

An alternative would be to create a TagHelper.

If you are thinking about inline if statement then you can do something like that:

@((string) ViewContext.RouteData.DataTokens["area"] == "Guest" ? "areaNav_link--selected" : string.Empty)
