【C#】医学检验系统（LIS）源码

**医学检验系统 (LIS) 源码**

**概述**

本项目是一个简单的医学检验系统 (LIS)，旨在模拟一个实际的医疗机构的检验流程。该系统包括用户管理、检验样本管理、检验结果管理等功能。

* .NET Framework4.8* C#7.3* Entity Framework Core3.1* ASP.NET Web API2.2**数据库设计**

我们使用 Entity Framework Core 来与数据库进行交互。下面是我们的数据库设计：

sqlCREATE TABLE Users (
 Id INT PRIMARY KEY,
 Name NVARCHAR(50),
 Email NVARCHAR(100)
);

CREATE TABLE Samples (
 Id INT PRIMARY KEY,
 PatientName NVARCHAR(50),
 SampleType NVARCHAR(20),
 Result DECIMAL(10,2)
);

CREATE TABLE Results (
 Id INT PRIMARY KEY,
 SampleId INT,
 ResultDate DATE,
 ResultValue DECIMAL(10,2),
 FOREIGN KEY (SampleId) REFERENCES Samples(Id)
);

csharppublic class User{
 public int Id { get; set; }

public class Result{
