看到书上的一个练习题,找出这段程序的问题,如果有问题就修改,没问题就写出结果
using System;
using System.Collections.Generic;
using System.Text;
enum Color
{
red, yellow, blue, green, purple, black, white
};namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Color[] color_arr = new Color[3];
int[] int_arr = new int[] { 0, 1, 2 };
color_arr = (Color[])int_arr; //运行的时候这里报错
Console.WriteLine("The value of color[0] is:{0}",color_arr[0]);
Console.WriteLine("The value of color[1] is:{0}", color_arr[1]);
Console.WriteLine("The value of color[2] is:{0}", color_arr[2]);
}
}
}虽然已经找到了错误,但是这么解决呢?不懂!
只好请教各位了!谢谢
顺便问一个非常简单的问题,如何能让命令行不会一运行完就自动关闭啊?

{
color_arr[0] = (Color)int_arr[i];
}
for (int i = 0; i < int_arr.Length; i++)
{
color_arr[i] = (Color)int_arr[i];
}
但是再问一个问题,为什么我用上面这位哥们儿给的代码,运行结果会是
The value of color[0] is:blue
The value of color[1] is:red
The value of color[2] is:red
高手请解释一下!谢谢
