Anonymous Class if the variable order not the same, the class types are not the same

I do some test with Anonymous Class:


var s1 = new { Name = "Tom", age = 35 };
var s2 = new { Name = "Eric", age = 35 };
var s3 = new { Name = "Eric", age = 35 };
var s4 = new { age = 35, Name = "Eric" };

Debug.Assert(s1 == s2);
//s1==s2 returns false
Debug.Assert(s1.age == s2.age);
//s1.age == s2.age retuns true
Debug.Assert(s2 == s3);
//s2==s3 returns false
Debug.Assert(s3== s4);
//There will have compile error in this case, as s3, s4 the
//anonymous class, the member orders are differenct, s3,s4 are
//considered as different types, compiling error out
Debug.Assert(s2.GetType() == s2.GetType());
//s2.GetType() == s3.GetType() retuns true
Debug.Assert(s3.GetType() == s4.GetType());
//s3.GetType() == s4.GetType() returns false
