What Is Tuple in C#

Introduction

 

Tuples were available before C# 7.0, but they were inefficient and had no language support. Issues in tuples in previous versions were that the elements in a tuple could only be referenced as Item1, Item2 and so on. C# 7.0 introduces improved tuples feature that enables semantic names for the fields of a tuple using new, more efficient tuple types.

 

Tuple is a class in C#.

 

Let us dive into it.

class Program
    {
        static void Main(string[] args)
        {
            var Result = Calculation(9, 3);
            Console.WriteLine("Addition " + Result.Item1);
            Console.WriteLine("Multiplication " + Result.Item2);
            Console.WriteLine("Subtraction " + Result.Item3);
            Console.WriteLine("Division " + Result.Item4);
            Console.ReadLine();
        }
        public static Tuple<int,int,int,int> Calculation(int x, int y)
        {
            int Add = x + y; // Addition
            int Mul = x * y; // Multiplication
            int Sub = x - y; // Subtraction
            int Div = x / y; // Division
            Tuple<int,int,int,int> t = Tuple.Create(Add, Mul, Sub, Div);
            return t;
        }
    }
}

Slightly changed in C#

class Program
    {
        static void Main(string[] args)
        {
            var Result = SumResult(9, 3);
            Console.WriteLine("Addition " + Result.Item1);
            Console.WriteLine("Multiplication " + Result.Item2);
            Console.WriteLine("Subtraction " + Result.Item3);
            Console.WriteLine("Division " + Result.Item4);
            Console.ReadLine();
        }
        public static (int,int,int,int) SumResult(int x, int y)
        {
            int Add = x + y; // Addition
            int Mul = x * y; // Multiplication
            int Sub = x - y; // Subtraction
            int Div = x / y; // Division
            return (Add, Mul, Sub,Div);
        }
    }

Feature of Tuple

class Program
    {
        static void Main(string[] args)
        {
            var (Addition, Multiplication, Subtraction, Division) = SumResult(9, 3);
            Console.WriteLine("Addition " + Addition);
            Console.WriteLine("Multiplication " + Multiplication);
            Console.WriteLine("Subtraction " + Subtraction);
            Console.WriteLine("Division " + Division);
            Console.ReadLine();
        }
        public static (int,int,int,int) SumResult(int x, int y)
        {
            int Add = x + y; // Addition
            int Mul = x * y; // Multiplication
            int Sub = x - y; // Subtraction
            int Div = x / y; // Division
            return (Add, Mul, Sub,Div);
        }
    }

We can define in this way:

static void Main(string[] args)
{
            var result = SumResult(9, 3);
            Console.WriteLine("Addition " + result.Addition);
            Console.WriteLine("Multiplication " + result.Multiplication);
            Console.WriteLine("Subtraction " + result.Subtraction);
            Console.WriteLine("Division " + result.Division);
            Console.ReadLine();
}
public static (int Addition, int Multiplication, int Subtraction, int Division) SumResult(int x, int y)
{
            int Add = x + y; // Addition
            int Mul = x * y; // Multiplication
            int Sub = x - y; // Subtraction
            int Div = x / y; // Division
            return (Add, Mul, Sub, Div);
}
