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 start and end indexes. You are allowed to find the start index of the given range with the help of the 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:

CSharp

// 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("Starting index of r1 range: " + res1);

        var res2 = r2.Start;
        Console.WriteLine("Starting index of r2 range: " + res2);
    }
}
}

Output:

Starting index of r1 range: 0
Starting index of r2 range: 3

Example 2:

CSharp

// 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 initializing 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
