linq 的用法小记－匿名类

这个代码里面用到了匿名类。
匿名类的用法， 感觉有点像JS里面的JSON了。但事实上，还是有区别的。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace LinqDemo
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btForeach_Click(object sender, EventArgs e)
        {
            List<Account> listAccount = CreateList();

            var accounts = from account in listAccount
                           orderby account.UserName
                           select new { account.UserName, account.Pwd };

            foreach (var account in accounts)
            {
                lvForeach.Items.Add(account.Pwd.ToString());
            }
        }
        List<Account> CreateList()
        {
            List<Account> list = new List<Account>();
            list.Add(new Account("account4", "Paccount4"));
            list.Add(new Account("account1", "Paccount1"));
            list.Add(new Account("account2", "Paccount2"));
            list.Add(new Account("account3", "Paccount3"));
            return list;
        }
    }

    public class Account
    {
        public string UserName
        {
            get;
            set;
        }
        public string Pwd
        {
            get;
            set;
        }
        public Account(string username,string pwd)
        {
            this.UserName = username;
            this.Pwd = pwd;
        }
    }
}
