1 创建实体类:
public partial class NewsCategory : IAggregationRoot
{
public NewsCategory() { }
public Guid Id { get; set; }
public string CategoryName { get; set; }
public bool IsDel { get; set; }
public string Code { get; set; }
}
2.创建实体类的映射伙伴类
public class NewsCategoryMap : IEntityTypeConfiguration<NewsCategory>
{
public void Configure(EntityTypeBuilder<NewsCategory> builder)
{
builder.ToTable("NewsCategory");
}
}
3.在上下文中 重写 OnModelCreating方法 将伙伴类的应用上
public class NewsEFCoreContext:DbContext,INewsContext
{ public DbSet<NewsCategory> Categories { get; set; } protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
//先直接写连接字符串，生成数据库。后续再在配置文件中配置，并使用到此处
optionsBuilder.UseSqlServer("Server=localhost;Database=wehope;User ID=sa;Password=0");
//optionsBuilder.UseSqlServer(AppSetting.GetAppSetting("DealerContext"));
} protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.ApplyConfiguration<NewsCategory>(new NewsCategoryMap());
base.OnModelCreating(modelBuilder);
}
}
完成。
