Once I've mapped my domain in NHibernate, how can I reverse lookup those mappings somewhere else in my code?

Example:

The entity Pony is mapped to a table named "AAZF1203" for some reason. (Stupid legacy database table names!) I want to find out that table name from the NH mappings using only the typeof(Pony) because I have to write a query elsewhere.

How can I make the following test pass?

private const string LegacyPonyTableName = "AAZF1203";

[Test]
public void MakeSureThatThePonyEntityIsMappedToCorrectTable()
{
    string ponyTable = GetNHibernateTableMappingFor(typeof(Pony));
    Assert.AreEqual(LegacyPonyTableName, ponyTable);
}

In other words, what does the GetNHibernateTableMappingFor(Type t) need to look like?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
