ASP.Net MVC: Calling a method from a view

Question

In my MVC app the controller gets the data (model) from an external API (so there is no model class being used) and passes that to the view. The data (model) has a container

Answer 1

Building on Amine's answer, create a helper like:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString CurrencyFormat(this HtmlHelper helper, string value)
    {
        var result = string.Format("{0:C2}", value);
        return new MvcHtmlString(result);
    }
}

in your view: use @Html.CurrencyFormat(model.value)

If you are doing simple formating like Standard Numeric Formats, then simple use string.Format() in your view like in the helper example above:

@string.Format("{0:C2}", model.value)
