How to compare two Dictionaries in C#

Question

I have two Generic Dictionaries.Both have same keys.But values can be different.I want to compare 2nd dictionary with 1st dictionary .If there are differences between values

Answer 1

You mentioned that both dictionaries have the same keys, so if this assumption is correct, you don't need anything fancy:

        foreach (var key in d1.Keys)
        {
            if (!d1[key].Equals(d2[key]))
            {
                d3.Add(key, d2[key]);
            }
        }

Or am I misunderstanding your problem?
