Answer 1

If you need to convert a List of objects (without Enums) to IEnumerable, you can use a declarative style of LINQ:

var items = from TipoDoc t in tipoDocs
                select new SelectListItem {Value = t.Id, Text = t.Description};

Here, tipoDocs is a List of objects of type TipoDoc

public class TipoDoc
{
    public string Id { get; set; }
    public string Description { get; set; }
}

Answer 2

have you tried

IEnumerable<SelectListItem> myCollection = dynamicTextEnumsAvaiable.AsEnumerable()

Answer 3

Maybe try this? (untested)

ViewBag.AvaiableEnums = dynamicTextEnumsAvaiable.Select(x => 
                                  new SelectListItem() 
                                  {
                                      Text = x.ToString()
                                  });

Answer 4

You could do the following

ViewBag.AvaiableEnums = new SelectList(dynamicTextEnumsAvaiable)

Answer 5

Just use .AsEnumerable() method.

Example:

IEnumerable<SelectListItem> myCollection = dynamicTextEnumsAvaiable.AsEnumerable()

Answer 6

You can maybe use a Linq statement to convert it

IEnumerable<SelectListItem> myCollection = dynamicTextEnumsAvaiable
                                           .Select(i => new SelectListItem()
                                                        {
                                                            Text = i.ToString(), 
                                                            Value = i
                                                        });
