本文实例讲述了c#实现基于链表的内存记事本。分享给大家供大家参考。具体如下:
user模型:
using system; using system.collections.generic; using system.linq; using system.text; namespace consoleapplication1 { public class user { private string username; public string username { get { return username; } set { username = value; } } private string sex; public string sex { get { return sex; } set { sex = value; } } private string age; public string age { get { return age; } set { age = value; } } private string phone; public string phone { get { return phone; } set { phone = value; } } } }
程序的灵魂controller:
using system; using system.collections.generic; using system.linq; using system.text; using system.collections; namespace consoleapplication1 { public class controller { private arraylist a = new arraylist(); public arraylist a { get { return a; } set { a = value; } } public void add(user user) { a.add(user); } public void delete(user user) { if (a.contains(user)) { a.remove(user); } else { console.writeline("用户不存在!"); } } public arraylist select(arraylist a) { return a; } public user search(string username) { foreach(user user in a) { if (user.username == username) { return user; } } return null; } } }
program.cs:
using system; using system.collections.generic; using system.linq; using system.text; using system.collections; namespace consoleapplication1 { class program { static void main(string[] args) { controller controller = new controller(); while (true) { console.writeline("请输入您的操作:"); console.writeline("1,增加用户"); console.writeline("2,删除用户"); console.writeline("3,浏览用户"); console.writeline("4,退出"); string input = console.readline(); if(input=="1") { user user = new user(); console.writeline("用户姓名:"); user.username = console.readline(); console.writeline("用户姓别:"); user.sex = console.readline(); console.writeline("用户年龄:"); user.age = console.readline(); console.writeline("电话号码:"); user.phone = console.readline(); controller.add(user); } if(input=="2") { console.writeline("请输入用户姓名"); string username = console.readline(); if (controller.search(username)!=null) { user user = controller.search(username); controller.delete(user); } else { console.writeline("该用户不存在!"); } } if(input=="3") { foreach(user user in controller.a ) { console.writeline(user.username); } } } } } }
希望本文所述对大家的c#程序设计有所帮助。
