Range Structure in C# 8.0 Last Updated : 12 Jul, 2025 Comments Improve Suggest changes 2 Likes Like Report Range struct predefined structure introduced in C# 8.0. This is used to represent a range that has start and end indexes. It provides a new style to create a range using the (..) operator. This operator is used to create a range that has a starting and ending index. It also allows the creation of a variable of the range type. It makes it easier to make slices of collections such as arrays, strings, and spans.Types of Range:Bounded Range: Specifies both start and end indices (e.g., 1..6)Unbounded Range: Specifies only start or end indices (e.g., ..4, 2.., ..)Example: C# // C# program to show how to create ranges using System; class Geeks { static void Main(string[] args) { int[] marks = new int[] {23, 45, 67, 88, 99, 56, 27, 67, 89, 90, 39}; // Creating variables of range type // And initialize the range // variables with a range // Using .. operator Range r1 = 1..5; Range r2 = 6..8; var a1 = marks[r1]; Console.Write("Marks List 1: "); foreach (var st_1 in a1) Console.Write($" {st_1} "); var a2 = marks[r2]; Console.Write("\nMarks List 2: "); foreach (var st_2 in a2) Console.Write($" {st_2} "); // Creating a range // Using .. operator var a3 = marks[2..4]; Console.Write("\nMarks List 3: "); foreach (var st_3 in a3) Console.Write($" {st_3} "); var a4 = marks[4..7]; Console.Write("\nMarks List 4: "); foreach (var st_4 in a4) Console.Write($" {st_4} "); } } Output: ConstructorRange(Index, Index): This constructor is used to create a new Range instance with the specified starting and ending indexes.Example: C# // C# Program to demonstrate Range Constructor class Geeks { public static void Main() { // Array var arr = new[] { 1, 2, 3, 4, 5, 6, 7, 8 }; // Range Created using the Range class constructor var r = new Range(2, 5); Console.WriteLine(String.Join(", ", arr[r])); } } Output: PropertiesAll: This property is used to get a Range object that starts from the first element to the end.End: This property is used to get an Index that represents the exclusive end index of the range.Start: This property is used to get the inclusive start index of the RangeExample: C# // C# Program to demonstrate Properties using System; class Geeks { public static void Main() { // Array int[] arr = { 1, 2, 3, 4, 5 }; // Create a range from the first element to the last Range range = 0..arr.Length; // Using Start and End properties Console.WriteLine("Start Index: " + range.Start.Value); Console.WriteLine("End Index: " + range.End.Value); // Display the range elements Console.WriteLine("Range Elements: " + string.Join(", ", arr[range])); } } Output: MethodsMethodDescriptionEndAt(Index)Used to create a Range object starting from the first element in the collection to a specified end index.Equals()Used to check whether the current range is equal to a specified range.GetHashCode()This method is used to find the hash code for this instance.GetOffsetAndLength(Int32)Used to calculate the start offset and length of the given range object with the help of a collection lengthStartAt(Index)Used to create a new Range instance starting from a specified start index to the end of the collection.ToString()Returns the string representation of the current Range object.Example: C# // C# Program to demonstrate Methods of Range Struct class Geeks { public static void Main() { // Array var arr = new[] { 1, 2, 3, 4, 5, 6, 7, 8 }; // Create a range from the first element to the last Range r = 0..arr.Length; // Create a range starting at index 2 Range r2 = Range.StartAt(2); // Create a range ending at index 3 Range r3 = Range.EndAt(3); // Display the Range object Console.WriteLine("Range of r: " + r.ToString()); // Display the elements of range Console.WriteLine("Elements of r: "+ String.Join(" ", arr[r])); Console.WriteLine("Elements of r2: "+ String.Join(" ", arr[r2])); Console.WriteLine("Elements of r3: "+ String.Join(" ", arr[r3])); // Checking equality of ranges Console.WriteLine("r3 is equal to r2: "+ r3.Equals(r2)); Console.WriteLine("r3 is equal to r: "+ r3.Equals(r));
