Diff between Assert.AreEqual and Assert.AreSame?

问题

What is the difference between Assert.AreEqual and Assert.AreSame?

回答1:

It means that AreSame() checks that they are the exact same object - if reference indicate the same object in memory.

AreEqual() checks that objects has equal type and value. Equal objects can exist in two different places in memory.

回答2:

Assert.AreEqual(a, b) is the same as Assert.IsTrue(Object.Equals(a, b))

Assert.AreSame(a, b) is the same as Assert.IsTrue(Object.ReferenceEquals(a, b))

(the only reason I knew is I just figured it out myself a few hours ago today because I needed to do a Assert.IsTrue(Object.ReferenceEquals(a,b)) and thought "I wonder if there is a better way to do this")
