Convert IDictionary<Guid,string> to the IEnumerable<SelectListItem>

Question

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

Answer 1

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).

Answer 2

如果要使用guid作为值，则可以使用

dictionary.Select(x => new SelectListItem  { Text = x.Value, Value = x.Key })

Answer 3

Something like this should do what you want:

var selectList = dictionary
    .OrderBy(kvp => kvp.Value) // Order the Select List by the dictionary value
    .Select(kvp => new SelectListItem
    {
        Selected = kvp.Key == model.SelectedGuid, // optional but would allow you to maintain the selection when re-displaying the view
        Text = kvp.Value,
        Value = kvp.Key
    })
    .ToList();

Answer 4

Using LINQ, you could do something like,

var theSelectList = from dictItem in dict
                    select new SelectListItem()
                    {
                        Text = dictItem.Value,
                        Value = dictItem.Key.ToString()
                    };
