NopCommerce 数据库初始化

NopCommerce数据库初始化比较复杂，我简化了，只初始化创建一张表，不多说，直接上代码：

//数据实体

/// <summary>
    /// Represents an affiliate
    /// </summary>
    public partial class Affiliate
    {
        /// <summary>
        /// Gets or sets the address identifier
        /// </summary>
        public int AddressId { get; set; }

        /// <summary>
        /// Gets or sets the admin comment
        /// </summary>
        public string AdminComment { get; set; }

        /// <summary>
        /// Gets or sets the friendly name for generated affiliate URL (by default affiliate ID is used)
        /// </summary>
        public string FriendlyUrlName { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether the entity has been deleted
        /// </summary>
        public bool Deleted { get; set; }

        /// <summary>
        /// Gets or sets a value indicating whether the entity is active
        /// </summary>
        public bool Active { get; set; }

    }

    public partial class AffiliateMap : NopEntityTypeConfiguration<Affiliate>
    {
        public AffiliateMap()
        {
            this.ToTable("Affiliate");//表名
            this.HasKey(a => a.AddressId);//设置主键
        }
    }

 public abstract class NopEntityTypeConfiguration<T> : EntityTypeConfiguration<T> where T : class
    {
        protected NopEntityTypeConfiguration()
        {
            PostInitialize();
        }

        /// <summary>
        /// Developers can override this method in custom partial classes
        /// in order to add some custom initialization code to constructors
        /// </summary>
        protected virtual void PostInitialize()
        {

        }
    }

//创建上下文 通过反射获取要加载的类

/// <summary>
    /// Object context
    /// </summary>
    public class NopObjectContext : DbContext
    {

        public DbSet<Affiliate> Affiliates { get; set; }

        /// <summary>
        ///
        /// </summary>
        /// <param name="modelBuilder"></param>
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            //dynamically load all configuration
            //System.Type configType = typeof(LanguageMap);   //any of your configuration classes here
            //var typesToRegister = Assembly.GetAssembly(configType).GetTypes()

            var typesToRegister = Assembly.GetExecutingAssembly().GetTypes()
            .Where(type => !String.IsNullOrEmpty(type.Namespace))
             .Where(type => type.BaseType != null && type.BaseType.IsGenericType &&
                 type.BaseType.GetGenericTypeDefinition() == typeof(NopEntityTypeConfiguration<>));
            foreach (var type in typesToRegister)
            {
                dynamic configurationInstance = Activator.CreateInstance(type);
                modelBuilder.Configurations.Add(configurationInstance);//获取此 DbModelBuilder 的 ConfigurationRegistrar。 注册器允许使用此生成器来注册派生的实体和复杂类型配置。
            }
            //...or do it manually below. For example,
            //modelBuilder.Configurations.Add(new LanguageMap());

            base.OnModelCreating(modelBuilder);
        }
    }

//测试

  Database.SetInitializer(new DropCreateDatabaseAlways<NopObjectContext>());//创建新的数据库
            using (NopObjectContext ctx = new NopObjectContext())
            {
                ctx.Database.Initialize(force: true);
            }

这里都结束了，当然Nop用的要复杂的多，这里都简单介绍哈
