Getting the hash code of the ValueTuple in C#
ValueTuple.GetHashCode Method is used to get the HashCode of the current ValueTuple instance. It is provided by the ValueTuple struct.
Syntax:
public override int GetHashCode ();
Returns: The return type of this method is System.Int32 and it always returns zero.
Example:
// C# program to illustrate how to // find the hash code of the given // value tuples. using System; class GFG { // Main method static public void Main() { // Creating a value tuple with zero element var MyTple1 = ValueTuple.Create(); Console.WriteLine( "HashCode of a value tuple with" + " zero elements: " + MyTple1.GetHashCode()); // Creating a value tuple with one element var MyTple2 = (23); Console.WriteLine( "HashCode of a value tuple " + "with one element: " + MyTple2.GetHashCode()); // Creating a value tuple with two elements var MyTple3 = (56, 45); Console.WriteLine( "HashCode of a value tuple " + "with two elements: " + MyTple3.GetHashCode()); // Creating a value tuple with three elements var MyTple4 = (67, 78, 89); Console.WriteLine( "HashCode of a value tuple with " + "three elements: " + MyTple4.GetHashCode()); // Creating a value tuple with four elements var MyTple5 = (09, 23, 12, 1); Console.WriteLine( "HashCode of a value tuple with " + "four elements: " + MyTple5.GetHashCode()); // Creating a value tuple with five elements var MyTple6 = (65, 87, 98, 23, 45); Console.WriteLine( "HashCode of a value tuple with" + " five elements: " + MyTple6.GetHashCode()); // Creating a value tuple with six elements var MyTple7 = (13, 56, 78, 12, 65, 98); Console.WriteLine( "HashCode of a value tuple with" + " six elements: " + MyTple7.GetHashCode()); // Creating a value tuple with seven elements var MyTple8 = (32, 45, 96, 78, 35, 33, 44); Console.WriteLine( "HashCode of a value tuple with" + " seven elements: " + MyTple8.GetHashCode()); } } |
Output:
HashCode of a value tuple with zero elements: 0 HashCode of a value tuple with one element: 23 HashCode of a value tuple with two elements: -818407567 HashCode of a value tuple with three elements: -1237760639 HashCode of a value tuple with four elements: 2105592814 HashCode of a value tuple with five elements: 695326364 HashCode of a value tuple with six elements: -335480823 HashCode of a value tuple with seven elements: -2111090807
