NHibernate ClassMap获取属性的列名

Question

我有ClassMap和实体。 在代码中，我想获取实体属性的列名。 任何想法？

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; }
}

我想问一下属性DepotId ，结果将是WPA_DEPOT_ID 。

Answer 1

有一个深入的概述：

探索Nhibernate映射

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

如何获得持久性：

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

以后可以迭代

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

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

Answer 2

使用上面的代码

这在我的情况下有效

List<string> columns = new List<string>();
        for (int i = 0; i < persister.PropertyNames.Count(); i++)
        {
            if (persister.GetPropertyColumnNames(i).Count() > 0)
            {
                columns.Add(persister.GetPropertyColumnNames(i).ToList().First());
            }
        }
