Question

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

public class AccountToDepotMap : ClassMap

        

Answer 1

There is an deep overview:

Exploring nhibernate mapping

And the simple code snippet from here

How do you get the database column name out of an auditing event listener in NHibernate

how to get the a persister:

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

which can be later iterated

// 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

using above code

This is working in my case

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());
            }
        }
