Code First Fluent API - 重命名不在模型中的AutoGenerated ForeignKeyID Db列-Java 学习之路

我遵循了Code First TPT继承的教程：http://weblogs.asp.net/manavi/archive/2010/12/28/inheritance-mapping-strategies-with-entity-framework-code-first-ctp5-part-2-table-per-type-tpt.aspx

用户模型包含对BillingDetail的单向导航 . CodeFirst命名列“BillingDetail_BillingDetailId”我想使用Fluent API重命名列“BillingDetailId” . 这是怎么做到的？这是用户模型 .

public class User
{
    public int UserId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public virtual BillingDetail BillingDetail { get; set; }
}

谢谢

你需要在User对象上使用BillingDetailId属性，然后通过流畅的API来实现

protected override void OnModelCreating(DbModelBuilder builder)
{
    builder.Entity<User>()
         .Property(u => u.BillingDetailId)
         .HasColumnName("BillingDetailId ");
}

因为您将“BillingDetail”作为属性...从此属性中提取的内容将具有ColumnName为“BillingDetailId”

protected override void OnModelCreating(DbModelBuilder builder)
{
     builder.Entity<User>().Property(u => u.BillingDetail).HasColumnName("BillingDetailId");
}
