Finding the Start Index 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 find the start index of the given range with the help of Start Property provided by the Range struct.
Syntax:
public property Index Start { Index get(); };
Here, Index represents the inclusive start index of the range.
Example 1:
// C# program to illustrate the use // of Start property 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(0, 5); // Creating range // using range operator Range r2 = 3..7; // Finding the Starting // index of r1 and r2 ranges // Using Start property var res1 = r1.Start; Console.WriteLine( "Staring index of r1 range: " + res1); var res2 = r2.Start; Console.WriteLine( "Starting index of r2 range: " + res2); } } } |

Output:
Staring index of r1 range: 0 Starting index of r2 range: 3
Example 2:
// C# program to illustrate how to use // Start property of Range structure using System; namespace range_example { class GFG { // Main Method static void Main( string [] args) { // Creating and initailizing an array string [] arr = new string [8] { "Archery" , "Badminton" , "Cricket" , "Bowling" , "Boxing" , "Curling" , "Tennis" , "Skateboarding" }; // Creating ranges // Using Range(Index, Index) // Constructor var r1 = new Range(0, 3); var r2 = new Range(4, 7); // Finding the start index // of the specified range // Using Start property var res1 = r1.Start; var res2 = r2.Start; Console.WriteLine( "Start Index of Range {0} is {1}" + " and the item is {2}" , r1, res1, arr[res1]); Console.WriteLine( "Start Index of Range {0} is {1}" + " and the item is {2}" , r2, res2, arr[res2]); } } } |

Output:
Start Index of Range 0..3 is 0 and the item is Archery Start Index of Range 4..7 is 4 and the item is Boxing
