NHibernate QueryOver.List extension to support casting to anonymous types

gistfile1.cs

public static IList<TRes> ListAs<TRes>(this IQueryOver qry, TRes resultByExample)
{
	var ctor = typeof (TRes).GetConstructors().First();
	return qry.UnderlyingCriteria
		.SetResultTransformer(Transformers.AliasToBeanConstructor(ctor))
		.List<TRes>();
}

[Fact]
public void ListAs_Should_CastQueryOverResultToTypeSameAsSupliedExampleInstance()
{
	var t = new { id = 0L, name = string.Empty };
	var data = Session.QueryOver<X>()
		.Where(x => x.Id == 123)
		.SelectList(sl => sl
			.Select(x => x.Id).WithAlias(() => t.id)
			.Select(x => x.Name).WithAlias(() => t.name)
		)
		.ListAs(t);

	Assert.Single(data);
	Assert.Equal(123L, data[0].id);
	Assert.Equal("name", data[0].name);
}

Nice one, can I write a blog regarding this?

"t" vs "dto" in your sample is a typo or not? I use it simply just as in the test I provided without any problems so far, but there may be some issues of course :)

and you can surely use it for a blog post - just provide a link to this gist and my name + website link, please..

I developed it exactly for the same purpose - simple NHibernate to json output :)
