Generate a sequence of numbers in C#

Generate a sequence of numbers in C#

In C#, you can generate a sequence of numbers using the Enumerable.Range method, which returns a sequence of integers within a specified range. Here's an example:

using System.Linq; public void GenerateSequenceOfNumbers() { // Generate a sequence of integers from 1 to 10 IEnumerable<int> sequence = Enumerable.Range(1, 10); // Output the sequence to the console foreach (int number in sequence) { Console.WriteLine(number); } }

In this example, the GenerateSequenceOfNumbers method generates a sequence of integers from 1 to 10 using the Enumerable.Range method. It then outputs the sequence to the console using a foreach loop.

You can also use the Enumerable.Repeat method to generate a sequence of a single value repeated a specified number of times. Here's an example:

using System.Linq; public void GenerateSequenceOfRepeatedValues() { // Generate a sequence of 5 zeros IEnumerable<int> sequence = Enumerable.Repeat(0, 5); // Output the sequence to the console foreach (int number in sequence) { Console.WriteLine(number); } }

In this example, the GenerateSequenceOfRepeatedValues method generates a sequence of 5 zeros using the Enumerable.Repeat method. It then outputs the sequence to the console using a foreach loop.

You can also use LINQ to manipulate and transform the generated sequences, such as filtering, sorting, or mapping the values to a different type.
