C# | How to get First Element of the Tuple?

  • Last Updated : 30 Apr, 2019

Tuple is a data structure which gives you the easiest way to represent a data set which has multiple values that may/may not be related to each other. Item1 Property is used to get the first element of the given tuple. It is applicable on every tuple like 1-Tuple, 2-Tuple, and so on.

Syntax:

public T1 Item1 { get; }

Here, T1 is the value of the current Tuple<> object’s first component. This Tuple<> can be 1-tuple, or 2-tuple, or 3-tuple, or 4-tuple, or 5-tuple, or 6-tuple, or 7-tuple, or 8-tuple.

Example: In the below code, you can see that we are accessing the first element of each tuple.




// C# program to illustrate how to get 
// the first element of the tuple
using System;
  
class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Taking 1-tuple
        var st1 = Tuple.Create("Mohan");
        Console.WriteLine("Student-1 Name: " + st1.Item1);
  
        // Taking 2-tuple
        var st2 = Tuple.Create("Sohan", 20);
        Console.WriteLine("Student-2 Name: " + st2.Item1);
  
        // Taking 3-tuple
        var st3 = Tuple.Create("Soniya", 30, "CSE");
        Console.WriteLine("Student-3 Name: " + st3.Item1);
  
        // Taking 4-tuple
        var st4 = Tuple.Create("Rohan", 29, "CSE", 2015);
        Console.WriteLine("Student-4 Name: " + st4.Item1);
  
        // Taking 5-tuple
        var st5 = Tuple.Create("Siya", 22, "CSE", 2017,
                                           "20-Mar-1993");
  
        Console.WriteLine("Student-5 Name: " + st5.Item1);
  
        // Taking 6-tuple
        var st6 = Tuple.Create("Riya", 24, "CSE", 2015,
                               "30-May-2015", 230134832);
  
        Console.WriteLine("Student-6 Name: " + st6.Item1);
  
        // Taking 7-tuple
        var st7 = Tuple.Create("Rohit", 21, "CSE", 2017, 
                        "21-Apr-1998", 384749829, 20000);
  
        Console.WriteLine("Student-7 Name: " + st7.Item1);
  
        // Taking 8-tuple
        var st8 = Tuple.Create("Manita", 24, "CSE", 2016, 
                   "03-Aug-1991", 235678909, 34000, "C#");
  
        Console.WriteLine("Student-8 Name: " + st8.Item1);
    }
}
Output:
Student-1 Name: Mohan
Student-2 Name: Sohan
Student-3 Name: Soniya
Student-4 Name: Rohan
Student-5 Name: Siya
Student-6 Name: Riya
Student-7 Name: Rohit
