C# Compare two dictionaries for equality

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

I like this approach because it gives more details when the test fails

    public void AssertSameDictionary(Dictionary expected,Dictionary actual)
    {
        string d1 = "expected";
        string d2 = "actual";
        Dictionary.KeyCollection keys1= expected.Keys;
        Dictionary.KeyCollection keys2= actual.Keys;
        if (actual.Keys.Count > expected.Keys.Count)
        {
            string tmp = d1;
            d1 = d2;
            d2 = tmp;
            Dictionary.KeyCollection tmpkeys = keys1;
            keys1 = keys2;
            keys2 = tmpkeys;
        }

        foreach(TKey key in keys1)
        {
            Assert.IsTrue(keys2.Contains(key), $"key '{key}' of {d1} dict was not found in {d2}");
        }
        foreach (TKey key in expected.Keys)
        {
            //already ensured they both have the same keys
            Assert.AreEqual(expected[key], actual[key], $"for key '{key}'");
        }
    }
