Getting the Hash Code of the Specified Range in C#
The Range Structure is introduced in C# 8.0. It represents a range that has a start and end indexes. You are allowed to get the hash code of the specified range with the help of the GetHashCode() Method provided by the Range struct. This method returns the hash code of the specified instance.
Syntax:
public override int GetHashCode();
Example 1:
// C# program to illustrate how to find // the hash code of the given ranges // Using GetHashCode() method of Range // struct using System; namespace range_example { class GFG { // Main Method static void Main( string [] args) { // Creating range // using Range constructor var r1 = new Range(2, 4); // Creating range // using Range operator Range r2 = 1..10; // Creating a range // using StartAt() method var r3 = Range.StartAt(4); // Get the hash code of the given ranges Console.WriteLine( "Hash Code of Range_1: " +r1.GetHashCode()); Console.WriteLine( "Hash Code of Range_2: " + r2.GetHashCode()); Console.WriteLine( "Hash Code of Range_3: " + r3.GetHashCode()); } } } |
Output:
Hash Code of Range_1: -1254614029 Hash Code of Range_2: 853498667 Hash Code of Range_3: -1528050329
Example 2:
// C# program to illustrate how to find // the hash code of the given ranges // Using GetHashCode() method of Range struct using System; namespace range_example { class GFG { // Main Method static void Main( string [] args) { // Creating and initializing an array int [] arr = new int [8] {100, 200, 300, 400, 500, 600, 700, 800}; // Creating a range // using StartAt() method var r = Range.StartAt(3); var new_arr = arr[r]; // Displaying the range // and the elements Console.WriteLine( "Range: " + r); Console.Write( "HashCodes: " ); foreach ( var i in new_arr) Console.Write($ " [{i.GetHashCode()}]" ); } } } |
Output:
Range: 3..^0 HashCodes: [400] [500] [600] [700] [800]
