Initializing the argument in NUnit 'TestCase' attribute

I haven't seen this on their Documentations, but I am looking to do a test like this:

[TestFixture]
public class SampleModel
{
    // stuff

    [TestCase(new DBContext(), 502)]
    public IQueryable<SomeModel> GetPrograms(DBContext dbContext, int? programId)
    {
        // Assert stuff
    }
}

Is it possible to initialize an argument in TestCase attribute?
