数组

 1，string[] names = {"小阿","小比","小才" };
            for (int i = 0; i < names.Length; i++)
            { string name=names[i];
            Console.WriteLine("{0}你好！", name);
            }

              
            Console.ReadKey();

2。  string[] =names;
            names[0]="a";
            names[1]="b";//报错原因为只是声明了变量但没有赋值
 string[] names("");
            names[0]="a";//为什么这里不报错？
            names[1]="b";//报错原因是数组的长度是确定的，无法动态增加长度
;//

string[] names = new string[5];//声明长度为5的string的数组
            names[0] = "fff";
            names[1] = "ffff";

              
            Console.ReadKey();

            /*  声明一个字符串数组，讲整数数组中的每一个元素的值转换为字符串保存到字符串数组中*/
            int[] values = { 3, 5, 8, 9, 100 };
            string[] strs = new string[values.Length];
            string[] names = new string[5];//声明长度为5的string的数组
            names[0] = "fff";
            names[1] = "ffff";
