+### 笔记
+```
+1 .一个类，在models中创建 
+2. 一个静态列表类，static，构造方法必须与方法类名相同，不需要返回值 
+3. 在views中创建列表页index，编辑页edit，新增页create，删除页delete 都要加上@model.mvc名.Models.studentinfo; 
+4. 在controllers创建控制器 
+5. 在控制器里声明index方法（主要是查找），传入参数string，这里的string参数名要调回到<input type="text" name="">name内 
+6. 声明create方法 
+7. 在index里面写查询： <form asp-action="index" method="get"> <input type="text" name=""> <button type="submit">查询</button> </form> 
+8. 在index.cshtml里面写编辑和删除：在tbody里写
+
+@foreach (var item in @Model)
+{
+    <tr>
+        <td>@item.Id</td>
+        <td>@item.Name</td>
+        <td>@item.Age</td>
+        <td>@item.Sex</td>
+        <td>@item.Hobby</td>

+### 安装Entity Feamework Core
+```
+1.命令：dotnet add package Microsoft.EntityFeameworkCore.SqlServer
+2.创建实体类型(数据模型)
+3.创建数据库上下文，配置好
+4.进行数据迁移(成功有两个前提：①程序不能编译错误；②程序必须停止运行)
+  命令：需要dotnet - ef工具 ，还需要一个依赖包，叫Microsoft.EntityFrameworkCore.Design
+  dotnet tool install --global dotnet -ef
+  dotnet add package Microsolf.EntityFrameworkCore.Design
+  dotnet ef migrations add Init
+5.将生成的数据迁移文件，同步更新到数据库，命令：dotnet ef database updata
