控制台程序下的泛型数组使用

Question

using System;
using System.Collections.Generic;
using System.Collections ;
using System.Text;这是头
问题：新建了一个LIST<>
                        struct N
                           {
                                int index;
                                int value;
                                int weight;
                           }
                        List < N > goods = new List<N>(); 
然后输入goods.   
1  输入goods时，提示框中没有出现goods
2  goods.后边的提示没有出现该问题多次出现，麻烦高手另外指点，这类问题在其它窗口程序中怎么处理？
接着，向goods中输入数据
                        for (int i = 0; i < count; i++)
                        {
                                goods.add();
                                Console.WriteLine ( "输入元素" );
                                goods[i] = Console.ReadLine ();
                                goods[i].index = i;
                        }
出现多出红色提示，不知道为什么，请大家帮帮忙，谢谢了！

Answer 1

上边的程序贴错了，应该为：
for (int i = 0; i <count ; i++)
   {
      goods.add();
      Console.WriteLine ("输入元素");
      goods[i].value;
      goods[i].weight;
      goods[i].index = i;
   }

Answer 2

请帖出完整代码，单看这段程序，有以下错误:for (int i = 0; i < count; i++)
                        {
                                goods.add();//方法Add的A应该大写，且必须接收一个N类型的参数
                                Console.WriteLine ( "输入元素" );
                                goods[i] = Console.ReadLine ();//Console.ReadLine()返回string类型，它怎么可能给goods[i]赋值？goods[i]是一个N类型的对象
                                goods[i].index = i;
                        } 

Answer 3

感谢您这么快的回复！代码如下：
using System;
using System.Collections.Generic;
using System.Collections ;
using System.Text;
namespace QiongJu
{
        class Program
        {
                static void Main(string[] args)
                {
                        struct N
                        {
                                int index;
                                int value;
                                int weight;
                        }
                        List < N > goods = new List<N>();      //所有的物品
                        List < N > T = new List<N>();     //存放所有可能的组合
                        static int m = 0;    //静态操作数组  便于操作
                        static int n = 0;
                        int bag = 20;   //袋子的承重量
                        static int count ;   //物品总数
                        Console .readline(count);
                        for (int i = 0; i < count; i++)
                        {
                                goods.add();
                                Console.WriteLine ( "输入元素" );
                                goods[i] = Console.ReadLine ();
                                goods[i].index = i;
                        }
                       
                        for ( int i = 0; i < count ;i++)
                        {
                                s = goods[i].weight ;
                                if ( bag >= s )
                                        T[m][n] = goods[i].weight ;  // 将第i件物品装入
                                                                                n++;
                                for (int k = i++; k < count ; k++)
                                {
                                        for ( int j = k; j < count ; j++)
                                        {
                                                s = s + goods[j].weight ;
                                                if (bag > s)
                                                {
                                                        T[m][n] = goods [j].weight ;
                                                        n++;
                                                }
                                                else
                                                {
                                                        m++;
                                                        n = 0;
                                                        s = goods [i].weight ;
                                                        break ;
                                                }
                                        }
                                }
                        }
                }
        }
}

Answer 4

汗……看来你连最基本的C#语法及逻辑都还没熟悉……
参考以下写法:        struct N
        {
            public int index;
            public int value;
            public int weight;
        } 
        static void Main(string[] args)
        {
            List<N> goods = new List<N>();
            int count = 3;
            for (int i = 0; i < count; i++)
            {
                N n = new N();
                Console.Write("请输入value:");
                n.index = i;
                n.value = int.Parse(Console.ReadLine());
                Console.Write("请输入weight:");
                n.weight = int.Parse(Console.ReadLine());
                goods.Add(n);
            }            foreach (N n in goods)
            {
                Console.WriteLine("index:{0},value:{1},weight:{2}", n.index, n.value, n.weight);
            }
        }

刚才修改如下：

Answer 6

谢谢上边的回答，但是不能提示的问题还是没有解决    
输入Console.也不能提示后边的，比如writeline   readline  等

Answer 7

goods[i].value = Console.ReadLine (); 
goods[i].weight = Console .ReadLine (); ReadLine读入的是一个String，需要Parse成int
如下：
string s = Console.ReadLine();
goods[i].value = int.Parse(s);

Answer 8

你说的不能提示后面的，应该是Intellisense出问题了，试试Ctrl+J，如果还不能出来，需要删除程序中那个.ncb文件，然后保证程序能编译通过，编译后它会自动update intellisense的。

Answer 9

先做好一個結構,再加到list當中去.你現在是先加,再創建好像有問題吧
  Goods.Add(goods)  //goods為創建好的結構
