NHibernate ClassMap获取属性的列名 [英] NHibernate ClassMap get column name for property

问题描述

我有ClassMap和实体.在代码中，我想获取实体中属性的列名.有想法吗?

I have ClassMap and entity. In code I would like to get column names for properties in entity. Any Idea?

public class AccountToDepotMap : ClassMap<AccountToDepot>
{
    public AccountToDepotMap()
    {
        Table("COPS_WPA_ACCOUNT_DEPOT");
        Id(t => t.RecId, "REC_ID");
        Map(t => t.RecordDate, "REC_DATE");
        Map(t => t.DepotId, "WPA_DEPOT_ID");
        Map(t => t.AccountId, "WPA_ACCOUNT_ID");
        Map(t => t.IsActive, "ISACTIVE").CustomType<YesNoType>();
    }
}

public class AccountToDepot
{
    public virtual long RecId { get; set; }
    public virtual DateTime RecordDate { get; set; }
    public virtual string DepotId { get; set; }
    public virtual string AccountId { get; set; }
    public virtual bool IsActive { get; set; }
}

我想问属性DepotId，结果将是WPA_DEPOT_ID.

I would like to ask on property DepotId and result will be WPA_DEPOT_ID.

还有这里的简单代码段

如何从NHibernate中的审核事件侦听器中获取数据库列名

如何获取持久性:

var entityType = typeof(TEntity);
var factory = ... // Get your ISessionFactory
var persister = factory.GetClassMetadata(entityType) as AbstractEntityPersister;

稍后可以迭代

// the set of Properties
var propertyNameList = persister.PropertyNames;

// here we get all the settings for remaining mapped properties
foreach (var propertyName in propertyNameList)
{
    ...
