MVC Model DisplayFormat for Array type attribute?

Question

I was wondering if I have a model class like this:

public class Contact
{
    public string Name { get; set; }
    public string[] Emails { get; set; }
}

In my View I use DisplayFor, so it does show all emails, but just as one string.

@Html.DisplayFor(modelItem => item.Emails)

[email protected]@[email protected]

Is there some kind of DisplayFormat attribute that I can apply to Emails property, so that it would display all emails for a single contact, separated by a comma, like this:

[email protected], [email protected], [email protected]

Dont really want to use foreach(var email in Model.Email) in my view for this simple operation.

Thanks.

try adding the appropriate programming language tag. In PHP i would use something like implode(Emails, ', '), i gues this language has a similar feature — Pevara

You could create an editor template. Check this out: coding-in.net/asp-net-mvc-3-how-to-use-editortemplates — Andre Calil

How about adding another string property to the ViewModel to represent a comma seperated version of the string array and use that in the view

public class Contact
{
    public string Name { get; set; }
    public string[] Emails { get; set; }
    public string EmailsCommaSeperated 
    { 
      get
      {
        return String.Join(",",Emails);
      }
    }
}

and use it as

@Html.DisplayFor(modelItem => item.EmailsCommaSeperated)

Wouldn't @Html.DisplayFor(modelItem => String.Join(", ", item.Emails)) work as well?

@AndreCalil: It is same thing. I want to keep it to the POCO(ViewModel) so that the View looks clean and readable without so many function calls.

I see. As this class is a model, and not a simple view model, I'd prefer not to add view logic to it. However, it's a minor decision. +1 for the straightforward suggestion

@AndreCalil: I edited the answer to include the ViewModel word.

You will need to create a custom helper.
