You could have a view model:

public class MyViewModel
{
    public Language SelectedLanguage { get; set; }
    public IEnumerable<SelectListItem> Languages
    {
        get 
        {
            var languages = 
                from l in Enum.GetValues(typeof(Language))
                select new { ID = (int)d, Name = d.ToString() };
            return new SelectList(languages , "ID", "Name", this.SelectedLanguage);
        }
    }
}

and then in your view:

@Html.DropDownListFor(x => x.SelectedLanguage, Model.Languages)

Another possibility is to write a custom helper that will encapsulate this logic as shown in this blog post.

This will do the job:

public enum Language
{
    English,
    French,
    Spanish
}

public static class Enum
{
    public static IEnumerable<T> GetItems<T>()
    {
        return System.Enum.GetValues(typeof(T)).Cast<T>();
    }
}

public class ViewModel
{
    public Language Language
    {
        get;
        set;
    }

    public IEnumerable<SelectListItem> Languages
    {
        get
        {
            return Enum.GetItems<Language>().Select(x => new SelectListItem() { Text = x.ToString(), Value = x.ToString() });
        }
    }
}

Html:

@model ViewModel
@Html.DropDownListFor(a => a.Language, Model.Languages)
