.NET平台程序与设计【6】 数组

数组

基本 没什么好讲的

就简单看一下这段吧，懂得都懂

            Dog[] myDogs = new Dog[3];
            myDogs[0] = new Dog("Buddy");
            myDogs[1] = new Dog("Cuddy");
            myDogs[2] = new Dog("Duddy");

            Dog temp = myDogs[0];
            myDogs[0] = myDogs[1];  
            myDogs[1] = temp;

C#特性，为数列添加新的元素

在c#中，使用Array.Resize方法来在数组中插入新元素。
具体用法：
Array.Resize(ref [数组名] , [新的数组长度])
书接上文：

            Dog[] myDogs = new Dog[3];
            myDogs[0] = new Dog("Buddy");
            myDogs[1] = new Dog("Cuddy");
            myDogs[2] = new Dog("Duddy");
            
            Array.Resize(ref myDogs, myDogs.Length + 1);//数组扩容
            myDogs[3] = new Dog("Pochi");//让第三位（新增的）命名波奇！

            for(int i = 0;  i < myDogs.Length; i++)
            {
                myDogs[i].Bark();
            }
            Console.ReadLine();
