一、数据库的建立

还是在fiber_yy数据库下创建images表
在这里插入图片描述
images表设计如下

二、页面完善设计

main_page页面进行功能完善
在这里插入图片描述
入库管理系统
warehousing页面

库存查询系统
query页面

登录注册页面前面几个博文已经实现过了，这里就再赘述了，仍是沿用前面的登录注册页面及数据库

三、代码实现

main_page页面

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

namespace fiber_yy
{
    
    
    public partial class main_page : Form
    {
    
    
        public main_page()
        {
    
    
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
    
    
            MessageBox.Show("退出成功");
            this.Close();
            new Form1().Show();
        }

        private void button2_Click(object sender, EventArgs e)
        {
    
    
            this.Close();
            new warehousing().Show();
        }

        private void button3_Click(object sender, EventArgs e)
        {
    
    
            this.Close();
            new shipment().Show();
        }

        private void button4_Click(object sender, EventArgs e)
        {
    
    
            this.Close();
            new query().Show();
        }
    }
}
