如何比较两个集合是否相等

 

            List<CustomerInfo> list1 = new List<CustomerInfo>()
            {
                new CustomerInfo(){ ID = 1, Name = "Tom"},
                new CustomerInfo(){ ID = 1, Name = "Tom"}
            };
            List<CustomerInfo> list2 = new List<CustomerInfo>()
            {
                new CustomerInfo(){ ID = 1, Name = "Tom"},
                new CustomerInfo(){ ID = 2, Name = "Tom"}
            };
 
            var b = list1.All(i => list2.All( j => j.ID == i.ID && j.Name == i.Name));

		//也可以尝试Any的用法

                //var b = list1.All(i => list2.All( j => j.ID == i.ID && j.Name == i.Name));

            Console.ReadKey();
