How do I put new List {1} in an NUNIT TestCase?

Question

I have the method:

public static int Add(List numbers)
    {
        if (numbers == null || numbers.Count == 0)
            return 0;

        if

There is one option to use TestCaseSource attribute. Here I provide a non-assert test with two cases just to see how it works:

[TestFixture]
public class TestClass
{
    private static readonly object[] _sourceLists = 
    {
        new object[] {new List {1}},   //case 1
        new object[] {new List {1, 2}} //case 2
    };

    [TestCaseSource("_sourceLists")]
    public void Test(List list)
    {
        foreach (var item in list)
            Console.WriteLine(item);
    }
}

Anyhow I have to mention it is not the most evident solution and I would prefer neatly organized fixtures ignoring the fact they are more verbose
