Getting the String that Represent the Value of the Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> Instance in C#

A tuple is a data structure that gives you the easiest way to represent a data set. You can also get a string that represents a tuple object by using the ToString Method. This method returns a string that will represent the Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object. The string represented by this method is in the form of (Item1, Item2, Item3, Item4, Item5, Item6, Item7, Item8..) here Item1, Item2, Item3, Item4, Item5, Item6, Item7 represent the values of Item1, Item2, Item3, Item4, Item5, Item6, Item7 properties, and Item8 represents the value of the Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object’s Next.Item1 property and the value of any additional nested components are followed by Item8. It will represent a String.Empty if any property contains a null value.

Syntax:

public override string ToString ();

Return Type: The return type of this method is System.String. So, it will return a string that represents Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object.

Example 1:

// C# program to illustrate
// the use of ToString method
using System;

namespace exampleoftuple {

class GFG {

    // Main Method
    static void Main(string[] args)
    {

        // 1-Tuple
        var v1 = Tuple.Create("Rohit");

        // Get the value of Tuple<T1>
        // With the help of ToString method
        Console.WriteLine("Tuple 1: " + v1.ToString());

        // 2-Tuple
        var v2 = Tuple.Create("Sheema", "Riya");

        // Get the value of Tuple<T1, T2>
        // With the help of ToString method
        Console.WriteLine("Tuple 2: " + v2.ToString());

        // 3-Tuple
        var v3 = Tuple.Create("Rima", "Suman", "Sohan");

        // Get the value of Tuple<T1, T2, T3>
        // With the help of ToString method
        Console.WriteLine("Tuple 3: " + v3.ToString());

        // 4-Tuple
        var v4 = Tuple.Create("Shilpa", "Susma",
                              "Sumit", "Rohan");

        // Get the value of Tuple<T1, T2, T3, T4>
        // With the help of ToString method
        Console.WriteLine("Tuple 4: " + v4.ToString());
    }
}
}

Output:

Tuple 1: (Rohit)
Tuple 2: (Sheema, Riya)
Tuple 3: (Rima, Suman, Sohan)
Tuple 4: (Shilpa, Susma, Sumit, Rohan)

Example 2:

// C# program to illustrate the
// use of ToString method
using System;

namespace exampleoftuple {

class GFG {

    // Main Method
    static void Main(string[] args)
    {
        // 5-Tuple
        var v5 = Tuple.Create("G", "E", "E", "K", "S");

        // Get the value of Tuple<T1, T2, T3, T4, T5>
        // With the help of ToString method
        Console.WriteLine("Tuple 5: " + v5.ToString());

        // 6-Tuple
        var v6 = Tuple.Create("C", "C#", "C++",
                     "Python", "Java", "Perl");

        // Get the value of Tuple<T1, T2, T3, T4, T5, T6>
        // With the help of ToString method
        Console.WriteLine("Tuple 6: " + v6.ToString());

        // 7-Tuple
        var v7 = Tuple.Create(12, 45, 67, 78, 87, 97, 87);

        // Get the value of Tuple<T1, T2,
        // T3, T4, T5, T6, T7>
        // With the help of ToString method
        Console.WriteLine("Tuple 7: " + v7.ToString());

        // 8-Tuple
        var v8 = Tuple.Create("G", "E", "E", "K", "S",
                 "F", "O", Tuple.Create("R", "G", "E",
                                      "E", "K", "S"));

        // Get the value of Tuple<<T1, T2, T3,
        // T4, T5, T6, T7, TRest>
        // With the help of ToString method
        Console.WriteLine("Tuple 8: " + v8.ToString());
    }
}
}

Output:

Tuple 5: (G, E, E, K, S)
Tuple 6: (C, C#, C++, Python, Java, Perl)
Tuple 7: (12, 45, 67, 78, 87, 97, 87)
Tuple 8: (G, E, E, K, S, F, O, (R, G, E, E, K, S))
