在C#中生成变量

问题描述

大家好
我想使用for循环或其他技术来生成数字变量.例如
我想生成5个变量以保存int值而不使用数组或列表或任何存储位置
我猜这个解决方案，我知道它不起作用:

Hello everyone
i want to Generate number Variable with for loop or another technique. for example
i want to Generate 5 variable to Save int Values without to use Array or list or any Storage locations
and i guess this solution and i know it''s not working :

for(int i = 0; i < 5; i++)
{
    Console.Write(" ID {0} : ",i+1);
    int ID = Convert.ToInt32(Console.ReadLine()); // ???? i don't want to override ID and i want to generate different ID to save different Values 
}

推荐答案

int[] ids = new int[5];

for(int i = 0; i < 5; i++)
{
    Console.Write(" ID {0} : ",i+1);
    ids[i] = Convert.ToInt32(Console.ReadLine());
}

int[] IDs = new int[5];
for (int i = 0; i < IDs.Length; i++)
   {
   Console.Write("ID {0} : ", i + 1);
   IDs[i] = Convert.ToInt32(Console.ReadLine());
   } 

int length = //...
int[] ids = new int[length];

for (int index = 0; index < length; ++index) {
    Console.Write(" ID {0}: ", index + 1);
    ids[index] = int.Parse(Console.ReadLine());
}

数组只是使对象(在这种情况下为整数类型)创建，可以访问，操作但没有单独名称(如变量)的一种方式.对象不必具有单独的名称，并且在许多情况下不能具有它们.其他情况包括集合，通过托管指针(引用)链接的任意对象图，其中链接表或树是此类图的简单示例.

Array is just one way of having the objects (of the integer type, in this case) which are created, can be accessed, manipulated, but have no individual names, such as variables. Objects do not have to have individual names, and, in many cases, cannot have them. Other cases include collections, arbitrary object graphs linked by managed pointers (references), with linked lists or trees being simple example of such graphs.
