What’s Wrong With This Code? (#22)
It’s a bug you’ve probably learned to avoid in .NET programming, it’s just not as obvious now.
var cities = new List<string> { "Baltimore", "Munich", "Copenhagen" }; var citiesToRemove = cities.Where(city => city.Length < 7); foreach (var s in citiesToRemove) { cities.Remove(s); }What goes wrong, and what’s an easy fix?
