V3022 False Positive

Question

PVS Studio throws V3022: Expression 'list.Count > 1' is always false. Program.cs 20

public class Program
{
    private static void Main()
    {
        var list = new List<string>();
        var keyvaluelist = new List<(string, string)>() { ("1", "2"), ("3", "4") };

        list.Add(DateTime.Now.ToString());

        foreach ((string Key, string Value) in keyvaluelist)
            list.Add(DateTime.Now.ToString());

        if (list.Count > 1)                    
            Console.WriteLine(list.Count);
    }
}

Is this a false positive?

Answer 1

This indeed looks like a false positive. We'll investigate it further and fix it in one of the future releases.

Also, as was mentioned in the comments before, false-positive reports are not the right format of questions for stackoverflow, so you can send them directly to PVS-Studio support at [email protected] or https://www.viva64.com/en/about-feedback/.

Thanks for your feedback!
