How i can convert IDictionary<Guid,string> to the IEnumerable<SelectListItem>?
I want to use string as SelectListItem.

Well you could just use
dictionary.Values().Select(x => new SelectedListItem { Text = x })
Just be aware that it may not be in a useful order: Dictionary<,> is inherently unordered (or rather, the order may change and shouldn't be relied on).
