C#对象比较的总结

            int m1 = 2;
            int m2 = 2;

            Console.WriteLine(m1 == m2);//值比较True
            Console.WriteLine(m1.Equals(m2));//值比较True
            Console.WriteLine(System.Object.ReferenceEquals(m1, m2));//引用False

            object m1 = 2;
            object m2 = 2;

            Console.WriteLine(m1 == m2);//引用类型引用比较False
            Console.WriteLine(m1.Equals(m2));//Object虚方法值比较True
            Console.WriteLine(System.Object.ReferenceEquals(m1, m2));//引用False
