A、数据库表引用先前建立的company 公司信息表。
B、建立文件：
views 》 Home 》 Company.cshtml****（新建文件） ，代码如下（直接复制即可）
@{
Layout = Layout = "~/Views/Shared/_Layout.cshtml"; ;
}
views 》 Home 》CompanyEdit.cshtml****（新建文件） ，代码如下（直接复制即可）
@model MiniUi_Dapper.Controllers.Company
@{
ViewBag.Title = "CompanyEdit";
Layout = "~/Views/Shared/_Layout.cshtml";
}
Controllers》HomeController.cs（控制器新建方法） ，代码如下（直接复制即可）
