advanced patterns with a for loop in C# when using LINQ to modify a collection
I'm prototyping a solution and I'm testing a new approach and I'm trying to figure out I've encountered a strange issue with This might be a silly question, but I'm working with a perplexing scenario in my C# application (using .NET 6.0) where I'm trying to filter and modify a collection using LINQ inside a for loop... The goal is to remove specific elements from a list based on certain conditions, but the behavior is not as expected. Here's the relevant code snippet: ```csharp using System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { List<int> numbers = new List<int> { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; for (int i = 0; i < numbers.Count; i++) { if (numbers[i] % 2 == 0) { // Attempting to remove even numbers numbers.Remove(numbers[i]); } } Console.WriteLine(string.Join(", ", numbers)); // Expecting odd numbers only } } ``` When I run this code, I expect to see only the odd numbers left in the list, but I get the output `1, 3, 5, 7, 9, 10`. It seems the for loop is skipping elements after removal. I've tried using `numbers.RemoveAt(i);` instead, but it leads to an `ArgumentOutOfRangeException` because the collection size changes while iterating. I also considered utilizing a `foreach` loop, but I'm aware that modifying a collection during iteration is generally problematic and can lead to runtime errors. I would appreciate any insights or workarounds to achieve my goal without running into these issues. What best practices should I follow in this scenario? What am I doing wrong? I'm working on a CLI tool that needs to handle this. Am I missing something obvious? Any help would be greatly appreciated! The stack includes C# and several other technologies. What would be the recommended way to handle this? For reference, this is a production desktop app. Has anyone else encountered this? My team is using C# for this REST API. What are your experiences with this? Thanks, I really appreciate it! My development environment is Ubuntu 20.04.
