实体框架7使用代码第一种方法复数表名

Question

我是ASP/EF的新手.我在我的个人项目中使用ASP 5和Entity Framework 7.

所以我能够使用代码优先方法创建数据库和表,但是所有表名都是单数的,默认情况下不会复数.

在我的ServerMatrixDemoDB DbContext文件中,我在DBSets下面创建了:

public class ServerMatrixDemoDB : DbContext
{
    public ServerMatrixDemoDB()
    {
        Database.EnsureCreated();
    }
    public DbSet<Domain> Domains { get; set; }
    public DbSet<Environment> Environments { get; set; }
    public DbSet<Network> Networks { get; set; }
    public DbSet<OsVersion> OsVersions { get; set; }
    public DbSet<Tier> Tiers { get; set; }
    public DbSet<Service> Services { get; set; }
    public DbSet<HardwareType> HardwareTypes { get; set; }
    public DbSet<Powershell> Powershell { get; set; }
    public DbSet<DotNetVersion> DotNetVersions { get; set; }
    public DbSet<Status> Status { get; set; }
    public DbSet<Servers> Servers { get; set; }
    public DbSet<Application> Applications { get; set; }

}

在我的startup.cs文件中,我使用下面的代码:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc()              // Add MVC Dependency.
        .AddJsonOptions(
            opt =>
            {
                opt.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); // Api convert all property names to CamelCase.
            }
        );
    services.AddLogging();          // Enable Logging for database errors.
    services.AddEntityFramework()
      .AddSqlServer()
      .AddDbContext<ServerMatrixDemoDB>(options =>
      {
          options.UseSqlServer(@"Server=.\SQLEXPRESS;user id=sa;password='passwrd';Database=ServerMatrixDemoDB;integrated security=True;");
      });
    services.AddTransient<ServerMatrixDemoSeedData>();
}

一旦我构建并运行项目,就会创建一个数据库和表,但所有表名都是单数.有没有办法在代码第一种方法中复数表名？

您可以在OnModelCreating重载中执行此操作,如 -

protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
      foreach (var entity in modelBuilder.Model.GetEntityTypes())
      {
        modelBuilder.Entity(entity.Name).ToTable(entity.Name + "s");
      }
    }

你也可以使用"数据注释"来做到这一点

    [Table("blogs")]
    public class Blog
    {
        public int BlogId { get; set; }
        public string Url { get; set; }
    }

或流利的Api

class MyContext : DbContext
    {
        public DbSet<Blog> Blogs { get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Blog>()
                .ToTable("blogs");
        }
    }
