c# 数组定义

网上数组定义很多讲解，感觉很零散，这里总结一下，备忘

class Program
    {
        static void Main(string[] args)
        {
            //1.声明并初始化数组大小
            //string[] array = new string[3];
            //for (int i = 0; i < 3; i++)
            //{
            //    array[i] = "a"+i.ToString();
            //}

            //2.声明并初始化数组的值
            //string[] array = { "a1", "a2", "a3" };

            //3.声明一个string数组
            //string[] array;//声明数组
            //array=new string[] {"a1","a2","a3"};//给数组初始化值

            //4.声明一个string数组
            string[] array;//声明数组
            array = new string[3];//初始化数组大小
            for (int i = 0; i < 3; i++)//给数组逐个赋值
            {
                array[i] = "a" + i.ToString();
            }

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

    }
