Asp.Net Core 2.0 生成操作数据库文件需要的文件

开发环境

VS2017 + Win7 x64

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

4、model 类
public class User
{
    [Key]
    public int Id { get; set; }
    public string UserName{get;set;}
}
5、DbContext 类
public class WebDemoDbContext: DbContext
{
    // 用户信息
    public virtual DbSet<User> User{ get; set; }

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

    }
}
