What is the best way to iterate over a Dictionary in C#?
In a Dictionary collection, store any data type. Dictionary is a collection of keys and values in C#. Dictionary<TKey, TValue> is included in the System.Collection.Generics namespace.
Let us now see the best way to iterate over a Dictionary in C# −
Firstly, let us create a dictionary −
var d = new Dictionary<string, int>(5);
Now add the key and value −
// add key and value d.Add("car", 25); d.Add("bus", 28); d.Add("motorbike", 17);
Use orderby to order by values −
var val = from ele in d orderby ele.Value ascending select ele;
We have set ascending above to sort the dictionary in ascending order. You can also use descending.
Display the values in ascending order −
foreach (KeyValuePair<string, int> ele in val) { Console.WriteLine("{0} = {1}", ele.Key, ele.Value); }
