C# | How to get First Element of the Tuple?
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 Student-8 Name: Manita
