Following is an example of using LINQ to sort c# Dictionary by Value:

  Dictionary<String, int> itemCount = new Dictionary<string,int>();<br /> itemCount.Add("abc", 2);<br /> itemCount.Add("edf", 3);<br /> itemCount.Add("gfh", 1);<br /> IEnumerable<KeyValuePair<String, int>> sortedDict =<br /> from entry in itemCount orderby entry.Value descending select entry;<br /> itemCount = sortedDict.ToDictionary(pair => pair.Key, pair => pair.Value);<br /> foreach (KeyValuePair<String, int> pair in itemCount)<br /> {<br /> Console.WriteLine(pair.Key + ":" + pair.Value);<br /> }
