Asp.Net Core 2.0 生成操作数据库文件需要的文件

开发环境

生成操作数据库文件需要配置或添加的文件

1、Startup.cs

public IConfiguration Configuration { get; }

// 为了引入配置文件。默认的配置文件为"AppSettings.json"。
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}

// This method gets called by the runtime. Use this method to add services to the container.
// For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940 public void ConfigureServices(IServiceCollection services)
{
// 添加 Entity Framework 服务，并且使用SQL Server  服务。
services.AddEntityFrameworkSqlServer().
AddDbContext<WebDemoDbContext>(option => option.UseSqlServer(Configuration["database:connection"]));

// 设置获取 appsettions.json 里的值
services.Configure<AppsettingOptions>(Configuration);
services.AddMvc();
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
// 调用wwwroot 里的文件
app.UseStaticFiles();

app.UseAuthentication();

// 默认首页
app.UseMvcWithDefaultRoute();

app.Run(async (context) =>
{
await context.Response.WriteAsync("Hello World!");
});
}

2、Program.cs

public class Program
{
public static void Main(string[] args)
{
BuildWebHost(args).Run();
}

public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.UseApplicationInsights()
.Build();
}

3、AppSettings.json

{
"database:connection": "Data Source=.;Initial Catalog=test;User ID=sa;Password=123"
}

Models 文件夹中

public class User
{
[Key]
public int Id { get; set; }
public string UserName{get;set;}
}

public class WebDemoDbContext: DbContext
{
// 用户信息
public virtual DbSet<User> User{ get; set; }

public WebDemoDbContext(DbContextOptions<WebDemoDbContext> options) : base(options)
{

}
}
