C#实现基于链表的内存记事本实例

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);
     }
    }
   }
  }
 }
}
