有没有人可以告诉我如何从键盘中给出值不是静态的应用程序，这是代码的一部分，这里是值静态的：

does any one can tell me how to give the value from keyboard not to be static in application, this is the part of code here is value static:

var city = new city(5);

这是一个类

and this is a class

class city { private readonly int[] _num; private readonly int _size; public city(int Size) { _size = Size; _num= new int[_size]; }

这只是为了让你适应代码....这个数字在新的城市（5） 。我想从tast进入，但我不能......

this is just to adapt you with code.... this number that is in new city(5). I want to enter from tast,,but I cant...

推荐答案

试试这个： Hi, Try this: int cityInt = -1; try { cityInt = Convert.ToInt32(Console.ReadLine()); } catch { Console.WriteLine("Input isn't an integer!"); } if (cityInt != -1) { var city = new city(cityInt); }

希望这有帮助。
