Deconstruction

Records can be deconstructed into separate variables.

Deconstruction

Deconstruction.cs 
using System;

record Pair(int Left, int Right)
{
    public override string ToString()
    {
        return Left + ":" + Right;
    }
}

class Program
{
    static void Main()
    {
        int right = ;
        Pair pair = new Pair(5, right);
        var (left, rightValue) = pair;
        int total = left + rightValue;

        Console.WriteLine($"right={right}");
        Console.WriteLine($"total={total}");
    }
}

using System;

record Pair(int Left, int Right)
{
    public override string ToString()
    {
        return Left + ":" + Right;
    }
}

class Program
{
    static void Main()
    {
        int right = ;
        Pair pair = new Pair(5, right);
        var (left, rightValue) = pair;
        int total = left + rightValue;

        Console.WriteLine($"right={right}");
        Console.WriteLine($"total={total}");
    }
}

using System;

record Pair(int Left, int Right)
{
    public override string ToString()
    {
        return Left + ":" + Right;
    }
}

class Program
{
    static void Main()
    {
        int right = ;
        Pair pair = new Pair(5, right);
        var (left, rightValue) = pair;
        int total = left + rightValue;

        Console.WriteLine($"right={right}");
        Console.WriteLine($"total={total}");
    }
}
deconstruction Deconstruction splits a value into named local variables.
