i tried this code: Dictionary dict = new Dictionary(); dict.Add("3", "three"); dict.Add("1", "one"); dict.Add("2", "two"); var sortedDict = (from entry in dict orderby entry.Key ascending select entry); This works, but sortedDict is not a dictionary. how can I make it a dictionary? also, i tried dict.OrderBy(x => x.Key); this does not work. why? – Cyan Jan 30 '11 at 02:02
solved it: dict = (from entry in dict orderby entry.Key ascending select entry).ToDictionary(x=>x.Key, x=>x.Value); – Cyan Jan 30 '11 at 02:10

i tried this code:

Dictionary<string, string> dict = new Dictionary<string,string>();
dict.Add("3", "three");
dict.Add("1", "one");
dict.Add("2", "two");

var sortedDict = (from entry in dict orderby entry.Key ascending select entry); 

foreach (var k in sortedDict)
{
    Console.WriteLine("key:{0}, val={1} ", k.Key, k.Value);
}

This works, but sortedDict is not a dictionary. I solved it:

sortedDict = (from entry in dict orderby entry.Key ascending select entry)
            .ToDictionary(x => x.Key, x => x.Value);
