Getting the Hash Code of the Specified Range in C# Last Updated : 12 Jul, 2025 Comments Improve Suggest changes Like Article Like Report 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: CSharp // 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: CSharp // 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] Create Quiz Comment A ankita_saini Follow 0 Improve A ankita_saini Follow 0 Improve Article Tags : C# CSharp-8.0 Explore IntroductionC# Tutorial 2 min read Introduction to .NET Framework 6 min read C# .NET Framework (Basic Architecture and Component Stack) 6 min read C# Hello World 2 min read Common Language Runtime (CLR) in C# 4 min read FundamentalsC# Identifiers 2 min read Data Types in C# 6 min read C# Variables 4 min read C# Literals 5 min read Operators in C# 7 min read C# Keywords 5 min read Control StatementsC# Decision Making (if, if-else, if-else-if ladder, nested if, switch, nested switch) 5 min read C# Switch Statement 4 min read Loops in C# 4 min read C# Jump Statements (Break, Continue, Goto, Return and Throw) 4 min read OOP ConceptsClass and Objects in C# 4 min read Constructors in C# 5 min read C# Inheritance 3 min read Encapsulation in C# 2 min read C# Abstraction 4 min read MethodsMethods in C# 4 min read Method Overloading in C# 4 min read Method Parameters in C# 4 min read Method Overriding in C# 7 min read Anonymous Method in C# 2 min read ArraysArrays in C# 6 min read Jagged Arrays in C# 4 min read Array Class in C# 5 min read How to Sort an Array in C# | Array.Sort() Method Set - 1 8 min read How to find the rank of an array in C# 2 min read ArrayListArrayList in C# 6 min read ArrayList Class in C# 4 min read C# | Array vs ArrayList 2 min read StringStrings in C# 6 min read C# Verbatim String Literal - @ 5 min read C# String Class 9 min read C# StringBuilder 2 min read C# String vs StringBuilder 3 min read TupleC# Tuple 7 min read C# Tuple Class 3 min read C# ValueTuple 7 min read C# ValueTuple Struct 4 min read IndexersC# Indexers 5 min read C# Multidimensional Indexers 5 min read C# - Overloading of Indexers 3 min read Like
