人力资源管理 winform C#

主旨思想：数据库（增，删，改，查）

资源管理器目的：实现基本人员信息   存储，调用，查看头像，修改内容。

注意事项：   1.建立两个表格  （人员表（cold，name，bumen，phone,topphone），头像表images（头像表两列cold，picture））

                 2.单独建两个类 ，存放列名的封装，放法（增，删，改，查）

                 3.listview   呈现表结够        

//第一个表
using System;
using System.Collections.Generic;
using System.Text;

namespace 晨启电子考勤系统.Cold
{
    public class useDATA
    {
        private string Name;

        public string Name1
        {
            get { return Name; }
            set { Name = value; }
        }
        private string ID;

        public string ID1
        {
            get { return ID; }
            set { ID = value; }
        }
        private string Chejian;

        public string Chejian1
        {
            get { return Chejian; }
            set { Chejian = value; }
        }
        private string Topphone;

        public string Topphone1
        {
            get { return Topphone; }
            set { Topphone = value; }
        }
        private string Phone;

        public string Phone1
        {
            get { return Phone; }
            set { Phone = value; }
        }
        private string qq;

        public string Qq
        {
            get { return qq; }
            set { qq = value; }
        }

    }
}
