文章标签 .net仓库管理系统源代码佳 c# sql 数据库 visual studio 文章分类 .Net 后端开发

设计思路及框架设计：

项目结构：

.net仓库管理系统源代码佳 c#仓库管理系统设计_visual studio

1.默认登录界面、注册功能设计

.net仓库管理系统源代码佳 c#仓库管理系统设计_c#_02

通过SqlConnection连接数据库，SqlCommand执行查询语句，ExecuteScalar()方法返回的结果判断是否查询到数据，决定是否登录！

.net仓库管理系统源代码佳 c#仓库管理系统设计_sql_03

判断是否查询到用户，决定是否注册成功！

2.主界面设计

.net仓库管理系统源代码佳 c#仓库管理系统设计_sql_04

主界面提供各管理页面的入口链接以及仓库环境监测功能！

.net仓库管理系统源代码佳 c#仓库管理系统设计_c#_05

环境监测采用用户控件的方式，通过SerialPort获取外设串口，再监测BytesToRead获取串口数据，最后传入的数据进行字符串解析，把相应值传入DrawLine，实现动态折线图页面！

3.商品管理页面设计

.net仓库管理系统源代码佳 c#仓库管理系统设计_sql_06

商品管理主页面，由SqlDataAdapter获取数据，通过DataTable展示页面，Fill填充数据到页面，ItemsSource设置页面的资源列表！
商品添加页面：

.net仓库管理系统源代码佳 c#仓库管理系统设计_sql_07

添加数据不能为空，获取填充数据进行insert SQL语句插入。
商品删除、修改操作：

.net仓库管理系统源代码佳 c#仓库管理系统设计_sql_08

通过cs验证库存，库存不为0的不可进行删改操作！

4．入库管理界面设计

.net仓库管理系统源代码佳 c#仓库管理系统设计_数据库_09

入库功能界面采用DataTable显示入库表，采用comboBox控件显示仓库中的商品，入库时插入入库记录并刷新仓库中的库存，达到入库功能！
删除入库记录功能：

.net仓库管理系统源代码佳 c#仓库管理系统设计_.net仓库管理系统源代码佳_10

删除不必要的入库记录！并刷新页面数据！

5．出库管理界面设计

.net仓库管理系统源代码佳 c#仓库管理系统设计_数据库_11

出库功能与入库功能相似，主要是修改库存之中的数据！

.net仓库管理系统源代码佳 c#仓库管理系统设计_visual studio_12

但当库存不足时，通过先行查找库存之中的数据进行校验，不足时提示出库失败！

6.用户管理界面

.net仓库管理系统源代码佳 c#仓库管理系统设计_visual studio_13

通过用户管理界面方便进行管理登录仓库账号！

因云盘易失效，故附项目源码如下：
