.NET Dictionaries have same keys and values, but aren't “equal”

Question

This test fails:

using Microsoft.VisualStudio.TestTools.UnitTesting;        

[TestMethod()]
        public void dictEqualTest() {
            IDictionary<         


        

Answer 1

You are completely not understanding how reference types work.

Dictionary does not override object.Equals(). Thus, it uses reference equality - basically, if both references are pointing to the same instance, they're equal, otherwise they aren't.
