helper method not printing anything

Question

I have created a helper method in view like this:

@helper DisputeOpenedDays(DateTime createdDate)
    {

        TimeSpan difference = DateTime.Now.Subtract(createdDate);
        string.Format("0", difference.Days);
}

and when I use it in view like this

@DisputeOpenedDays(myobj.CreatedAt)

It doesnt print any thing

Answer 1

@helper DisputeOpenedDays(DateTime createdDate)
{
 TimeSpan difference = DateTime.Now.Subtract(createdDate);
 @string.Format("{0}", difference.Days);
}

Answer 2

Try:

string.Format("{0}", difference.Days);

The curly braces are missing.
