推荐答案

最好是在该列表中创建所需对象的类. 然后将您的列表定义为:

Best would be to create a class of the objects you want in that list
and then define your List as:

List<yourclass>  Listname  = new List<yourclass>();

using System;
using System.Collections.Generic;
using System.Linq;

namespace PrintPrice
{
    class Price
    {
        static void Main()
        {
            List<int> list = new List<int>();
            list.Add(1);
            list.Add(2);

            // Count with the Count property.
            int c = list.Count;
            Console.WriteLine(c);

            // Count with the extension method. This is different!
            c = list.Count(); // BE CAREFUL!
            Console.WriteLine(c);

            Console.ReadKey();
        }
    }
}

public class MyObject
{
    public string Name { get; set; }
    public string Description { get; set; }
    public MyObject():this("", "")
    {
    }
    public MyObject(string name, string desc)
    {
        this.Name = name;
        this.Description = desc;
    }
}

public class MyObjectCollection() : List<MyObject>
{
}

用法:

Usage:

MyObjectCollection objects = new MyO bjectCollection();
objects.Add(new MyObject("John", "Outlaw Programmer"));
// or
objects.Add(new MyObject() { Name="John", Description="Outlawprogrammer" } );
// or
MyObject obj = new MyObject("John", "Outlaw Programmer");
objects.Add(obj);
// or
MyObject obj = new MyObject(){Name="John", Description="Outlaw Programmer"};
objects.Add(obj);
