Dictionary Keys and Values to a Select List

Question

Dictionary<string,string> dict = new Dictionary<string,string>();       dict.add("a1", "Car");   dict.add("a2", "Van");   dict.add("a3", "Bus"); 

---

SelectList SelectList = new SelectList((IEnumerable)mylist, "ID", "Name", selectedValue); 

In above code I have put a list mylist to a SelectList. ID and Name are two properties of that particular object list(mylist).

Likewise I need to add the Dictionary to the SelectList.

---

Need to add the key of the dictionary to the data Value parameter -(ID position of above example) Need to add the value of the dictionary to the data text parameter -(Name position of the above example)

So please tell me a way to create a select list using this dictionary keys and values without creating a new class.

Answer 1

You could try:

SelectList SelectList = new SelectList((IEnumerable)dict, "Key", "Value", selectedValue); 

Dictionary<string, string> implements IEnumerable<KeyValuePair<string, string>>, and KeyValuePair gives you the Key and Value properties.

Be aware, however, that the order of items returned by enumerating a Dictionary<string,string> is not guaranteed. If you want a guaranteed order, you can do something like:

SelectList SelectList = new SelectList(dict.OrderBy(x => x.Value), "Key", "Value", selectedValue);
