What is the best way to iterate over a dictionary?

Question

I\'ve seen a few different ways to iterate over a dictionary in C#. Is there a standard way?

Answer 1

With .NET Framework 4.7 one can use decomposition

var fruits = new Dictionary();
...
foreach (var (fruit, number) in fruits)
{
    Console.WriteLine(fruit + ": " + number);
}

To make this code work on lower C# versions, add System.ValueTuple NuGet package and write somewhere

public static class MyExtensions
{
    public static void Deconstruct(this KeyValuePair tuple,
        out T1 key, out T2 value)
    {
        key = tuple.Key;
        value = tuple.Value;
    }
}
