Question

I want to compare in C# two dictionaries with as keys a string and as value a list of ints. I assume two dictionaries to be equal when they both ha

Answer 1

Most of the answers are iterating the dictionaries multiple times while it should be simple:

    static bool AreEqual(IDictionary thisItems, IDictionary otherItems)
    {
        if (thisItems.Count != otherItems.Count)
        {
            return false;
        }
        var thisKeys = thisItems.Keys;
        foreach (var key in thisKeys)
        {
            if (!(otherItems.TryGetValue(key, out var value) &&
                  string.Equals(thisItems[key], value, StringComparison.OrdinalIgnoreCase)))
            {
                return false;
            }
        }
        return true;
    }
