基于SAP.NET Core Web APP （MVC）的医疗记录管理系统完整开发指南

摘要：Web programming ASP .NET Core课程设计要求如下，请给出详细的新建项目步骤，生成完整的项目代码，给出代码设计思路，数据库EF关系图，以及每个数据表的意义，详细的代码注释。开发平台是VS2022，数据存取要用数据库，数据库要有初始化的一些数据。支持医生登录，管理员登录。欢迎页面点击login进行登录，登录后实现下面的任务。最好是该系统支持国际语言切换，网页显示要美观，形成蓝色主题医院。代码注释用英语，最终网页显示的默认语言是英语。项目描述如下：

概述
一家医院希望使用一个网站，以便医生能够更轻松地访问患者的医疗记录。医疗记录包含患者的所有信息：姓氏、名字、地址、社会安全号码、任何过敏情况，以及初级保健医生的详细信息（姓名、名字、地址、专业注册号）。
过敏情况有编码，并且危险等级从 1 到 10 不等。系统必须记录患者从何时开始过敏以及何时结束。一旦过敏治愈，就不会再次出现。
如果患者姓名发生变化（例如结婚），必须保留出生姓名（婚前姓氏）和当前姓名（现用名）。
医疗记录包含对患者进行的所有医疗操作，包括操作名称、摘要、日期和时间，以及任何相关的数字文件。例如，对于 X 光检查，图像文件必须在记录中可用。
任何治疗患者的医生都必须能够访问该患者的所有信息。每位医生都有：

医院特有的唯一标识符
姓名、名字、地址- 就业信息：具有唯一标识符、名称和职能（角色）的服务（部门）内的一份工作。医生可能会变更服务部门和/或职能。有些医生可能拥有多个角色，并在多个服务部门工作。对于每个职位，系统必须存储医生的资历（以工作月数计算）。
医院由多个服务部门组成，每个服务部门都有唯一的标识符和位置。并非所有医生都能访问所有病人的医疗记录——他们只能访问其当前服务部门内病人的记录。
病人可能会经过多个服务部门，也可能在不同日期多次经过同一个服务部门。既是医生又是病人的人员将被视为普通病人。鉴于此类情况的数量与总病人数量相比非常少，一定程度的数据冗余是可以接受的。
2 网站
网站界面将允许医生使用用户名和密码登录，并访问其有权查看的病人的医疗记录。
1 医生能够为病人添加新的干预措施，但不能修改或删除之前的干预措施。将能够更新有关患者身份的信息。
由于文件（例如 X 光片）可能很大，系统必须允许不在页面上直接显示文件，而是显示从文件中提取的关键元数据作为占位符。

一、项目创建步骤

1. 创建新项目

1. 打开 Visual Studio 2022
2. 点击 "Create a new project"
3. 选择 "ASP.NET Core Web App (Model-View-Controller)"
4. 项目名称: MedicalRecordSystem
5. Framework: .NET 8.0 (或 .NET 7.0)
6. Authentication type: None (我们将自定义实现)
7. 勾选 "Configure for HTTPS"
8. 点击 "Create"

2. 安装 NuGet 包

# 在 Package Manager Console 中执行
Install-Package Microsoft.EntityFrameworkCore.SqlServer
Install-Package Microsoft.EntityFrameworkCore.Tools
Install-Package Microsoft.AspNetCore.Session
Install-Package Microsoft.Extensions.Localization
Install-Package BCrypt.Net-Next
