What is the best way to iterate over a dictionary in C#?

In the Dictionary collection, store any data type. A dictionary is a collection of keys and values ​​in C#. Dictionary is contained in the System.Collection.Generics namespace.

Now let us see the best way to iterate over a dictionary in C# -

First, let us create the dictionary -

var d = new Dictionary<string, int>(5);

Now add the keys and values ​​-

// add key and value
d.Add("car", 25);
d.Add("bus", 28);
d.Add("motorbike", 17);

Use orderby to sort by value−

var val = from ele in d
orderby ele.Value ascending
select ele;

We set the ascending order above to sort the dictionary in ascending order. You can also use descending order.

Display values ​​in ascending order -

foreach (KeyValuePair<string, int> ele in val) {
   Console.WriteLine("{0} = {1}", ele.Key, ele.Value);
}
