What's the most simple way to convert comma separated string to int[] in C#?

The most straightforward way to convert a comma-separated string to an int[] (integer array) in C# is by using the Split method and Select method from LINQ to parse each element and convert it to an integer. Here's a simple one-liner using LINQ:

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        string input = "1,2,3,4,5";
        int[] result = input.Split(',').Select(int.Parse).ToArray();

        // Now 'result' contains the integer array {1, 2, 3, 4, 5}
        foreach (int number in result)
        {
            Console.WriteLine(number);
        }
    }
}

In this example, the input string contains comma-separated values. We use the Split method to split the string into an array of substrings using the comma as the delimiter. Then, we use the Select method to parse each substring and convert it to an integer using int.Parse. Finally, we call ToArray to convert the result to an int[].

This approach assumes that the input string is well-formatted, and all elements can be successfully converted to integers. If there is any chance of invalid input, you should consider using int.TryParse in the Select method to handle parsing errors and handle them accordingly.
